I don't know how that video does not have millions of views and why more people have not tried to build one, this is absolutely one of the coolest projects
Because not everyone has to pay for electricity at prices like in California. Places where electricity is 10c/kWh or less have no incentive to use solar right now, even if they were in the middle of a desert. It could be an environmental choice if you were getting your electricity by fossil fuel, but there are places running mostly (if not only) on hydro, wind, solar or tidal power.
@Agent Office - so you are mean and ignorant. great @NewTech - in california rates vary, off-peak for me costs 14 cents and peak 49 cents, Summer rates are higher than winter and there is also a tier system where your rates get higher after you past certain amount of energy, for me tier 2 starts past 10kWh per day
*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*
I picked up 6 of these modules, plus 4 tesla model s modules and a 6kw 24v LF inverter and a 12kw 48v LF inverter to test at my house and in my youtube studio. I also have a 20kw generac wholehouse backup geni that will kick in if needed. I have 800w of PV now and have a few shipping containers full of panels on the way. Jehu great vid as usual.
Awesome pair of Guys to be talking about this. Great to see yous working on this project together. Would love to see the pair of you in more projects and talks.
The battery pack in the event of grid power outage becomes a generator for another word for those used to using gas gennies. And really guys, it's a good video from start to end and who cares how he says roof, really?!? geeze!!!! Space saver, safer and longer lasting then deep cell batteries!!!! Great video, first time viewer, and subbing, thanks for all of the info!!!!
Very simple to get around code/ grid. Install the off grid system with dedicated duplex outlets just plug into those outlets. Also very easy to install a transfer switch for generator back up power, use the solar panels system in lieu of generator. I plan to install separate dedicated solar power outlets for main TV room, computers, stereo system that's the majority of the electrical I use. Some of the outdoor individual garden lights can be set up indoors for cheep general lighting (solar panels set outside the windows)
Super to know that there are others like me. I operate a 2.5KW system with three banks of 24VDC. It's a great feeling to operate a non grid tie system. I have been improving it every year for the last 5 years. I'm a master electrician with 35 years in the field. Thanks so much for making this video. I save about 40 percent on my utility bill per month and looking to increasing the my grid into next year.
That panel is about $7000 cost. + 2400 inverter, + 250 for the fuse panel, + 1000 for the other 2 panels. 11,650 dollars. .12 per kwh. =97000 kilowatt hour recovery cost in today's money. That's about 1142 Tesla Model S full 85 kwh charges assuming a perfect world and 100% efficiency. That's about 10 per full charge which is in line with Tesla estimate for a 300 mile charge (listed as $12). That's cool. But, the return on investment, assuming 100 miles a day (heavy estimate average) you would simply have to drive your vehicles for about 3000 days to break even in today's money, that's 9.38 years for 1 car driven 100 miles every day of the year. If you have a fleet, then say 5 cars an average of 30 miles 5 days a week, which is 150 miles per day or 750 per week. That's about the same payback (since you likely aren't drivi g all 5 more on average). So your investment, assuming labor costs and maitenance cost and replacement costs will likely reach 16000 easily over a 9 year span will only slightly offset the increase in enervy costs. Economically speaking, 11000 invested in bond at 3% would net you 3700 bucks in 9 years and could have paid for 31000 kw or 375 charges at full 85. Assuming only 1/3, that's 1000 charges. Seems like a lot of money to spend. 16000 cash invested into a 3% dividend investment blue chip could net 5500 over 10 years plus any stock increase. Snice after about 10 years, it's unlikely your system will be 100 efficient, and will still require manpower and maintenance, it's not a bargain. The intrinsic value is only environmental, but not economical. Imho
Thanks for the post. Very cool. There are so many ways to do this stuff that anything is possible. Hey, I have a half dozen "dead" UPS's here. LOL All had the inverter go dead. And, when we got there, they overcharged the batteries and destroyed them as well. I won't tell you the level of money flushed down the drain, as it would hurt. I'm still tossing around between lithium and lead acid. That's the really hard part in designing a system. Thanks again.
In my humble opinion off grid is the way to get into solar. All the stuff you have to do to grid tie is expensive and extra money spent means a longer payback period. I have an off grid system that works like a charms. I built it myself to meet all electrical codes.
Be the change "Two cool guys here. Love the attitude, Mr. Garcia and the sharing of knowledge." USELESS knowledge; this is only "DIY" if you're a professional installer. No ordinary Joe is going to be able to rig up this shit; and it doesn't even pay off if they could.
There's a trick to starting APC UPS box. Must have proper battery voltage before plugging AC power. Also, you can start without AC altogether. Again, start with proper battery voltage, push power button ( I ) one time, push power second time and hold until you hear beep, then release. I use my APC smart 2200 UPS this way with solar and lead acid. No AC power!! Powers my 8000 btu air conditioner. No problem. I'm very interested in seeing you get this working with lithium ion. Thanks for all the great videos!
I really do understand why you use these batteries they are cheap and great, but they are design for high power application and will give you around 1000 to MAX 1500 cycles before the are really bad, the cells planed for use in the new Teslawall are NMC cells they will give you a much longer life, when you say you wall will last for 25 years and we assume your batterys are brand new ( 1000 Cycles left ) it can give you around 4 kwh on average every day, a fair number when you take into account that your cells are not new would be 5 - 10 years :-) but for everyone who can get hold of these cells "go get them" :-) in DK they are not available jet, and i personally like Lifepo4 more, so my own battery is made up of 864 x 3.2v 30Ah Lifepo4 cells giving a total of around 85kwh, Lifepo4 have a lower energy density but is much safer and will give you more than 2000 cycles before the capacity goes below 80% of the original capacity, the size of my battery is based on a daily power consumption of 20kwh, at that rate the math is 85kwh / 20 = 4,25 days pr. cycle ,times 2000 = 8500 days / 360 = 23,6 years, when you take into account that much of the summer i will use power directly from the solar system the 20kwh pr. day is very high, but i will assume the lifespan to be 25 years.
Very well thought out. Thank you for showing people what is necessary to get the math right. lifespan of 25 years is great! let's hope battery tech leaps ahead over the next few years!
Given the source of those modules (Smart EV), I'd bet they're first gen LiCo batteries -- i.e. "firecrackers". It's possible they're second gen, and thus somewhat less prone to exploding (thermal runaway.) I don't know what the gigafactory will be putting in the 2170's. Third gen NMC would be my guess, but I don't know. Panasonic doesn't say. That said, temperature, rate of charge/discharge, and depth of discharge are what ages batteries. Repeated deep discharges will significantly reduce their lifespan. All of this is well documented in datasheets.
Main thing is to have an extremely large base of power storage but to thread light on its drain capabilty...that way even lead acids will last very long time...eg if you use 3kilowatt per day make sure you have 100kilowatt storage or more...idea is not to over stress the batteries.
in the netherlands we can sell the solar energy back for same prices as we bought the energy from the grid (netting). So we use the grid as virtual battery so we don't need a power wall. But how is it in USA?
They only restriction is that when you got more energy in a year than you have used. The price of the extra energy that you put in the grid will drop otherwise you become a power station. They do like this because high amount of CO2 in the netherlands...
Most people that buy solar for their house here in the USA do connect to the grid. It's the diy people that make them with batteries. You need extra stuff that the electric company approves of to connect to the grid. Some solar companies do offer the battery option. I've seen a bunch of camps in the NE that use the off the grid battery option because it's better than using a geny or running power lines.
that would be a problem mipmip but in 20 years we never had power outage more than 2 days. so is not that big of problem. And hospitals got gas generators incase of emergency
Jehu: Love this and all your videos. A note about UPS's: They are designed to provide AC power for short periods only. I would not consider using one as a full-time inverter. The circuitry isn't there for long-term AC power generation. But, after saying that, they are cheap.
Is this transferable to a mobile, off grid caravanning system? I’ve been trying to find the best solar set up for a sprinter van and lithium seems much better than the popular led acid/wet/agm/gel but there’s way less info for lithium being applied to caravanning.
Hi Jehu, love you 'tubes. I have been watching you and some others [HBPowerwall, etc.] for a while. Very interesting stuff. I am dabbling with 18650's myself at the moment [starting anyway] and find it very good to see what others are doing. Keep it going, Frank.
Man, would LOVE to be doing this with my weekends instead of fixing up my rental properties in the hood.....now if I can just make it similarly profitable. lol
Thanks for showing this. A few thoughts: BMS isn't just a luxury or something you should use when you think your batteries might need levelizing, it's a safety measure to prevent overcharging and fires. Also, you get more smiles per photon when you use tech to massage your batteries, right, so a BMS should be a priority with BEVs, not a privilege. Just ask to fools who burned down their houses overcharging LiFePO4 hobby packs to power their ebikes. If I misunderstood, and you do have a BMS inline, I apologize for the tongue lashing. Also, please don't fondle your high voltage electronics with your bare hands like he does in this video when it's hot. It's a bad habit to get into. You can point, without touching. Lastly, just because a solar installation isn't grid tied, it doesn't mean you don't need a permit and inspections. Lots of folks do stuff without a permit, but please be careful not to instruct other people that it wasn't required.
Elon musk may crash and burn, but they say hes got electric cars in the spotlight. Even if you do as well Jehu, Im sure you have inspired a lot of people with your videos. I think you've got the stuff of an engineer, a born engineer.
FYi guys, I did the math on this when the powerwall was announced. A DIY, Rolls-Surrette, lead acid powerwall would cost less than half of the Tesla powerwall and last 4 times longer. Of course, the batteries are much larger, but that's the only problem with it. I included a battery management system, as well as a power distribution system in the costing, so its a total system price. Top of the line Lead Acid cannot be beaten for price per Amp Hour, per Year. The Batteries they use for the Tesla Powerwall will need to be replaced long, long before the Rolls-Surrettes will. The only technology that can beat Lead Acid on a price/Amp Hour/Cycle Life comparison is, believe it or not, nickel/Iron batteries, as pioneered by Edison himself. Unfortunately they are not sold commercially. EDIT: I am wrong about this. They are sold commercially. And they are expensive.. which should tell you something about their longevity.Look up 'Edison battery'.
Its not about Watt Hours. Its about Watt Hours *extracted* per cycle, per dollar expended on the battery. Do a spreadsheet incorporating cycle life and price and you'll see. And for those who don't believe me, it's 20 minutes of work on a spreadsheet to figure this out. Do the work and you'll see for yourself.
love you guys for the detailed showcase, your efforts and enthusiasm in the EV & EV charging stuff. It is so cool to know that the era of oil-dictation is about to fall with no doubt and everyday we can work on the progress of improving our future. Greets from Germany (The part in Europe that unfortunately clings the most to the old world of fossil fueled cars) and keep up the good work Jehu and Michael :) !
Good luck trying to charge anything when you have smoke from any surrounding fires. we are off grid and had to run a gen-set to keep our fire sprinklers pressurized.
Ugh, it's terrible, right? Knowing nothing about this, I'd assume that post-processing could invert the sounds at these frequencies and more-or-less kill this buzz. Somebody more informed can correct me, or confirm this.
Excellent video! Very inspiring! I was planning on waiting for the Tesla Powerwall to become available. Now that I've seen this, I don't know if I can wait. I also don't know if that's the solution that works best for me, knowing how much more kWh I would get using this setup than using the Tesla Powerwall. Got some serious thinking to do. I would love to see more on this!
Man I wish I was smart enough to do this on my own. Maybe it is easy for people with the knowledge, and maybe it's a little fear mixed in. But I'd be scared of getting electrocuted, and just wasting money with trials and errors. Either way I'm dying for something like this. Hope I can find a guy like this when I get back home.
You're smart enough, there is just a huge amount of information and choices, so it tends to overload the brain, which causes one to want to hide in the bathroom a lot. Once you decide exactly what you want to do, and use it for, it gets a little less daunting. The hardest part is deciding on what kind of batteries you want to use. (I'm still wrestling with this) Just take your time, read and view posts, and follow the path it takes you. Hang in there.
Thanks! Your right. I found some simpler versions, and just started with the super basic one battery, and one solar panel. I fell more confident now. But like you said I just need to do the research. Hope you figure out what you want to use. Maybe make a video ;)
Have you thought about coming up with a tesla power wall for a motorhome? When I look at the Tesla website you can pre-order a powerwall with around 13kwh in the 6k range - that's dirt cheap for that kind of storage. Combine that with solar charge controller and inverter and you'd have a killer RV off grid setup even allowing you to run a small air conditioner.
Thanks for posting. Tesla/SolarCity said in their 2Q earnings conference call last week that they have considerable existing backlog in their ability to supply product for commercial storage demand. That's for commercial uses, as opposed to consumer or residential applications. I've seen rumors that Tesla already sold their entire 2016 production capability for storage, and have therefore, been unable to provide PowerWalls to the residential market in the USA. Hence, no PowerWalls available.
Great video and have watched many of yours and find that you are a genuine person that cares about sharing information when you find it. Thanks, also if you can do a short video on the components used and name them including where to buy them from it will help others create their power walls and put a little more pressure on the power companies to stop fucking around with the simplest of things and help the average person live a decent life without getting gouged every step of the way. Thank you and great job.
you have compressor and 2 fan motors amp surge when the unit starts. measure it with a clamp on amp meter. try adding a hard start kit to the a/c unit. not sure how to size to a 120 v system. visit a hvac vendor store and ask them.
Pretty good price on the tesla battery packs if they have the capacity they are rated at. Just couple of mistakes on the website I found. According to the datasheet the cell is 3.6v nominal and 2.7Ah rated capacity. So the capacity of the pack should be 59.4Ah, 3.2kWh. Nominal pack voltage should be 54V and not 57V.
Makes me want to build my own... but I'd be going blind reading all teh technical stuff I'd have to to make the stuff safe... Still this is very cool stuff... subscribed!
It would be great to be "off the grid" but most cities won't allow you to be off the grid. How are we going to change if cities, townships, etc. won't allow this type of electrical independence?
I have off grid systems in over 40 states. You can put off grid power anywhere you want, you just have to do it with a professional system and the people who know how to do it correct. I can permit anywhere with my engineered designs.
Very informative with Array controller inverted scenario. Battery Bank clever. Good info. click pops no problem, Skippy in the background got a little annoying. Overall nice job on the video. Sustainability Rocks...
Very easy to do this for half the cost of the Tesla wall. DIYev.com is coming out with classes and kits soon. Get used batteries!! Good idea and cost effective. These guys are very informative. Good job.
Yes, I am currently trying to figure out how long the Li-ion battery's will last. Panasonic suggest that their batteries (used in Tesla powerwall) wil degrade 25% after 500 cycles of 100% capacity (that's from 4.2V tot 3.0V) At a Daily use, that's about 1.3 years.
I love this video, but please explain how you installed a high power electrical system and you don't need a permit. Especially in California, I live in NJ and I don't think I could just install an electrical system in my house without having the town inspect it.
This is excellent project !! Thanks for telling the cost, very nice !! I love it...That's why they don't want you to use and can't access that huge 40-60kW battery pack inside EV and go EV-to-House,because in combination with solar,that would be OFF grid for everyone !!!
Hey, two way street here, you going to be critical of my video, im going to be critical of your comments, This video contains tons of good info and you are going to concentrate on the background noise? you are a terrible viewer, show appreciation for the good or MOVE ALONG
really man? for someone who has some good content this was a terrible way to reply to concerns about audio being bad. I personally am 80% deaf and the pops were distracting. Just take the criticism to heart and test your audio next time. Humility always wins in the end.
Acually I think this idea has potential - I was thinking about this for some time. I dont think this would be great for personal vehicles - although it wouldnt need to affect aerodynamics in any way. However, with anything bigger than that like trucks this is surely the future. It would help much more than 100ft.
This is super cool. I am surprised not more smaller companies do this. One question, when you have this system operational, how easy is this to tie into the grid? what restrictions will you have to deal with? and what device(s) will you need to get it connected?
Dude. I have watched a couple of your videos. First I would like to say your so cute. I have a request and a question. my request is can you make a video in girl language. like It all sounds so complicated. Perhaps just say like you need this and this and this and connect it to this and this and this. you can get it here and it costs this much and once it is set up all you have to do is this every so often.My question is based on my future plans for living off grid. I'm single and have no intention of having any future with a guy around to help me. so i need to know how to do stuff alone. I have ten acres in Florida and hope to convert a two-story tough shed into a tiny home for myself. would one wall run my house. There is no power or water access on this property so I have a lot of work cut out for me. I was also wondering if i would need to be connected to the grid with a wall. I'm hoping not as a power pole and such in its self is expensive.
This is a really good. We need to think out of the box. When someone think out of the box and have have the courage to show it to the world only good things happen. Go ahead my friend and proof your concept.........Ahhhh... As I know... Those 48 volt smart ups's have to be programmed when you put fitter end batteries. Maybe that's the problem....
start small man , he spent 9000 on batteries .... if he didnt have those , he could still run things and charge his car ... only when the suns out ... at least in the day your saving money then
As my 8 kW solar system generates way more than I consume, I requested to my utilities that the excess kWh be carried forward as a credit from month to month indefinitely until I terminate service. This means I don't sell my excess power, which I would only get 5 cents/kWh compared to the 10 cents/kWh that I pay. It's a better deal for me as long as I know I'm going to eventually use that excess kWh eventually. I know I will as I have an electric brewery that I use frequently during the winter. It's a better deal for my utilities as well, since they need the Renewable Energy Credits for government funding (I think).
I'm guessing you don't charge an electric car as well as run your house? I'm still 'surrounding' the parameters (numbers) on a similar system to this video for our house. During AC season, we use 70 kwh per day, just for the house. Charging a car every 3rd day would add about 10 kwh/day more. We have numerous public charging stations and my wife charges at work, so those factors are nebulous. The sun shines 6 to 8 hours per day, almost every day. So we'd need a 70+10=80/7 hours = 11 kw system. But that's on paper. Ironically, the first problem is the system is too big for most of the year. I've got it. We'll add a pool. A more practical answer is to reduce the size of everything but the battery pack (bigger is always better) and find energy reductions throughout the houses' design. There are lots of place to improve, such as isolating all this exterior stucco from the sun.
I apparently saw this video before... But why are you charging the car through an inverter? Wouldn't it be more efficient to charge with a DC charging unit thus skipping the inverter and whatever losses are incurred in the inverter? It seems redundant to invert DC to 220VAC and then back to whatever the charger wants in DC. Wouldn't it be better to just convert the wall DC to the DC voltage the charger needs? Can you not get a charger that can use DC as an input?
Nice, he just gave you credit for a smart idea that you had for a tool. Dude this is awesome, I'd love to work with you. I'm also struggling financially and it's tough man.
I know with a lot of UPS systems they require Batteries to make them work. Even when you plug them in and they do not power up they still need some kind of small load to make it happen. With my UPS even though the battery said needs to be replaced. When i unplug the Batteries from it the UPS doesn't power up at all.
I mean I love the idea and to actually get it set up where it worked would be very cool. I think that your 300 Tesla wall idea makes it much more doable. I think if you got the Harbor Freight Solar Panels it might look a little better as to the idea of worth it. Do you think it is a good idea to use Harbor Freight panels as to cost of other more reliable ones? Love the channel and Subbed by the way!
+John Stephanites harbor freight panels are not the best value, 45w for $149 Amazon has a 100w panel for $112 and you can get $30 charge controller. More than double the wattage for same price
that's how it all works, ever diminishing return means it might take longer, this is modern day snake oil salesmen trying to make you think it will pay for itself in 10 years, in reality it will be 15-20 but it wont hast half that. Think how many people's vaporizer batteries are exploding, imagine these doing that after 5 years and them blaming you for bad charging practices.
Amazing setup. I know it's been 9 months, so you may not see this question. If you do, dont suppose you could share details of where you got the batteries (make/model) and other components you used? I am in Australia and very keen to get into this type of battery technology for a home project.
These particular batteries were probably made is a limited quantity. I don't know if it is possible to get more, but they were purchased here. evbatterycenter.com. The Tesla 24v packs. I don't think getting them to Australia would be cost effective. Best to find out which electric car is most popular in AUS and find batteries from that model. The solar equipment you can't see in picture is all off the shelf stuff from Schneider Electric Solar. Bus bars and cables to connect the batteries were all custom made.
You need to get into RV. think about a min home with with a pair of 24 volt alternators rated at 300 amp each just going to waste. this is not the hole story it only gets more compelling. love your channel.
Jehu I absolutely love your work and vids. Its all very enriching. Would like to know if you can offer some help in my project? I have a used 2011 Prius battery that I pulled out of my Prius and wanted to know after I recondition this. If I can somehow use this for my power wall. If so, what would I need to complete this project with all needed parts to power my 1000 watt air conditioner and possibly a few lights for now with the possibility for expansion. Thank you very much in advance.
Anyone who thinks this in any way "sustainable" simply does not understand the word "sustainable." There is nothing sustainable about this. Worse, it is not scalable. These type of projects are causing people to go down this road of unsustainable "solutions."
+dosmastrinfy Can everyone do this? More importantly, can we run the interstate highway system using this? It might be useful for individuals, it might make sense for the guy in the video, but this can't be done at scale. Electric vehicles are simply not going to replace diesel and petrol engines. There is zero evidence showing that PVs are net energy generators. Go look for it, you simply cannot find it.
+dosmstrify There is no evidence to support that PV panels generate more energy than it took to create them in the first place (energy returned on energy invested or EROI). The best studies show energy consumption across the production process, but none of them take all of the embedded energy into consideration. Specifically they leave out the energy needed to create the supply chain (bulldozers, factories, trucks, boats etc) along with the highly technical civilization needed to make all this possible. Even the most optimistic looks at PV shows relatively low EROI, especially when it is compared to oil. This might seem like nitpicking, but it really isn't. We have a "budget" of energy we can use in the next 30 years if we want to avoid the worst of climate change (for example). We can blow this energy any way we want. If we spend this "budget" on alternatives that turn out not to be large net energy producers (at least 15x), we will have have squandered this budget. It is not at all clear to me that PV and batteries are a good solution.
Don't you need a permit for any modification to a building. You have panels on roof and electrical wiring. You need to get a electrical permit from the city of Los Angeles (building and safety), and a permit from LADWP to connect to the grid. You would still need city permit.
im curious how they test those used batteries. 3000 charges is about the best your going to get out of 18650's that are new and as far as i know u cant really test for how many charge cycles its gone through. a curious technology that might work great with a large array is the tech in SSD's. they do interesting stuff to try and spread the load around reducing read write cycles and increasing the lifecycle of its ram, or if used in this, a battery. would require a large oversized array though.
Been toying with this idea, we don't get enough sun in winter to live off solar, but could still charge battery at night with hydro then run off it all day during on peak, while solar adds a bit of power for a few hours. In the summer months solar would provide most of the power. I don't have much room on my roof though, so I'd only be able to do like 1-2kw at most. But that part of the roof faces south so that's a bonus. (other areas get shade from trees)
Hi there, If this happens to be written in poor English, I apologize. I'm from The Netherlands. I was wondering for what reason your UPS system isn't working. I bought myself a used APC UPS (about 5 kW real sine), but I haven't tested it yet. So please explain. About the Tesla Powerwall. I don't think it is very useful, for it can only drain 2 kW max. So having 7 or 10 kW sounds great, but you'll find the bottleneck at the level of the inverter. Looking forward to hearing from you. Best regards, Roelof
Intersting. looked up the Tesla Powerwall recommended for my size house. It says 2 reccommended and the cost is $12,500 not counting install costs which they estimate at $800 to $2000. So the price of the wall in this video is pretty damn competitive.

you mean to say the price is higher in places where there is more sun. how does that work? How expensive is it in California?

Very simple to get around code/ grid. Install the off grid system with dedicated duplex outlets just plug into those outlets. Also very easy to install a transfer switch for generator back up power, use the solar panels system in lieu of generator. I plan to install separate dedicated solar power outlets for main TV room, computers, stereo system that's the majority of the electrical I use. Some of the outdoor individual garden lights can be set up indoors for cheep general lighting (solar panels set outside the windows)
My E bill is $200 a month X 12 = $2,400 a year
$2,400 x 20 = $48,000
Save $32,000
Its worth doing....
Can you generate $200 worth do electricity per month, every month, with a $16,000 investment ?
@@vtorsi610 😄😄
Super to know that there are others like me. I operate a 2.5KW system with three banks of 24VDC. It's a great feeling to operate a non grid tie system. I have been improving it every year for the last 5 years. I'm a master electrician with 35 years in the field. Thanks so much for making this video. I save about 40 percent on my utility bill per month and looking to increasing the my grid into next year.
That panel is about $7000 cost. + 2400 inverter, + 250 for the fuse panel, + 1000 for the other 2 panels. 11,650 dollars.
.12 per kwh. =97000 kilowatt hour recovery cost in today's money.
That's about 1142 Tesla Model S full 85 kwh charges assuming a perfect world and 100% efficiency. That's about 10 per full charge which is in line with Tesla estimate for a 300 mile charge (listed as $12).
That's cool. But, the return on investment, assuming 100 miles a day (heavy estimate average) you would simply have to drive your vehicles for about 3000 days to break even in today's money, that's 9.38 years for 1 car driven 100 miles every day of the year. If you have a fleet, then say 5 cars an average of 30 miles 5 days a week, which is 150 miles per day or 750 per week. That's about the same payback (since you likely aren't drivi g all 5 more on average).
So your investment, assuming labor costs and maitenance cost and replacement costs will likely reach 16000 easily over a 9 year span will only slightly offset the increase in enervy costs. Economically speaking, 11000 invested in bond at 3% would net you 3700 bucks in 9 years and could have paid for 31000 kw or 375 charges at full 85. Assuming only 1/3, that's 1000 charges.
Seems like a lot of money to spend. 16000 cash invested into a 3% dividend investment blue chip could net 5500 over 10 years plus any stock increase. Snice after about 10 years, it's unlikely your system will be 100 efficient, and will still require manpower and maintenance, it's not a bargain. The intrinsic value is only environmental, but not economical. Imho
+David Boyanich all charging on this shop powerwall is done at day rates of $.49 here in California.
Yeah, but can you run your refrigerator and air conditioner when the power is out for four days?
😎😎😎😎😎😎
Thanks for the post. Very cool. There are so many ways to do this stuff that anything is possible. Hey, I have a half dozen "dead" UPS's here. LOL All had the inverter go dead. And, when we got there, they overcharged the batteries and destroyed them as well. I won't tell you the level of money flushed down the drain, as it would hurt. I'm still tossing around between lithium and lead acid. That's the really hard part in designing a system. Thanks again.
Great job Jehu and Michael. Nice video.
In my humble opinion off grid is the way to get into solar. All the stuff you have to do to grid tie is expensive and extra money spent means a longer payback period. I have an off grid system that works like a charms. I built it myself to meet all electrical codes.
Esp installation
Two cool guys here. Love the attitude, Mr. Garcia and the sharing of knowledge.
Be the change "Two cool guys here. Love the attitude, Mr. Garcia and the sharing of knowledge."
USELESS knowledge; this is only "DIY" if you're a professional installer. No ordinary Joe is going to be able to rig up this shit; and it doesn't even pay off if they could.
There's a trick to starting APC UPS box. Must have proper battery voltage before plugging AC power. Also, you can start without AC altogether. Again, start with proper battery voltage, push power button ( I ) one time, push power second time and hold until you hear beep, then release. I use my APC smart 2200 UPS this way with solar and lead acid. No AC power!! Powers my 8000 btu air conditioner. No problem. I'm very interested in seeing you get this working with lithium ion. Thanks for all the great videos!
I really do understand why you use these batteries they are cheap and great, but they are design for high power application and will give you around 1000 to MAX 1500 cycles before the are really bad, the cells planed for use in the new Teslawall are NMC cells they will give you a much longer life, when you say you wall will last for 25 years and we assume your batterys are brand new ( 1000 Cycles left ) it can give you around 4 kwh on average every day, a fair number when you take into account that your cells are not new would be 5 - 10 years :-) but for everyone who can get hold of these cells "go get them" :-) in DK they are not available jet, and i personally like Lifepo4 more, so my own battery is made up of 864 x 3.2v 30Ah Lifepo4 cells giving a total of around 85kwh, Lifepo4 have a lower energy density but is much safer and will give you more than 2000 cycles before the capacity goes below 80% of the original capacity, the size of my battery is based on a daily power consumption of 20kwh, at that rate the math is 85kwh / 20 = 4,25 days pr. cycle ,times 2000 = 8500 days / 360 = 23,6 years, when you take into account that much of the summer i will use power directly from the solar system the 20kwh pr. day is very high, but i will assume the lifespan to be 25 years.
Very well thought out. Thank you for showing people what is necessary to get the math right. lifespan of 25 years is great! let's hope battery tech leaps ahead over the next few years!
Given the source of those modules (Smart EV), I'd bet they're first gen LiCo batteries -- i.e. "firecrackers". It's possible they're second gen, and thus somewhat less prone to exploding (thermal runaway.) I don't know what the gigafactory will be putting in the 2170's. Third gen NMC would be my guess, but I don't know. Panasonic doesn't say.
That said, temperature, rate of charge/discharge, and depth of discharge are what ages batteries. Repeated deep discharges will significantly reduce their lifespan. All of this is well documented in datasheets.
Main thing is to have an extremely large base of power storage but to thread light on its drain capabilty...that way even lead acids will last very long time...eg if you use 3kilowatt per day make sure you have 100kilowatt storage or more...idea is not to over stress the batteries.
This is much better content than I'd expect from a relatively low subscriber count. I'm surprised!
in the netherlands we can sell the solar energy back for same prices as we bought the energy from the grid (netting). So we use the grid as virtual battery so we don't need a power wall. But how is it in USA?
thats genius, i think in uk we pay more for it than it can be sold for
They only restriction is that when you got more energy in a year than you have used. The price of the extra energy that you put in the grid will drop otherwise you become a power station. They do like this because high amount of CO2 in the netherlands...
Most people that buy solar for their house here in the USA do connect to the grid. It's the diy people that make them with batteries. You need extra stuff that the electric company approves of to connect to the grid. Some solar companies do offer the battery option. I've seen a bunch of camps in the NE that use the off the grid battery option because it's better than using a geny or running power lines.
that would be a problem mipmip but in 20 years we never had power outage more than 2 days. so is not that big of problem. And hospitals got gas generators incase of emergency
Also our houses mostly run on gas,
Jehu:
Love this and all your videos.
A note about UPS's: They are designed to provide AC power for short periods only. I would not consider using one as a full-time inverter. The circuitry isn't there for long-term AC power generation. But, after saying that, they are cheap.
Is this transferable to a mobile, off grid caravanning system? I’ve been trying to find the best solar set up for a sprinter van and lithium seems much better than the popular led acid/wet/agm/gel but there’s way less info for lithium being applied to caravanning.
Hi Jehu, love you 'tubes. I have been watching you and some others [HBPowerwall, etc.] for a while. Very interesting stuff. I am dabbling with 18650's myself at the moment [starting anyway] and find it very good to see what others are doing. Keep it going, Frank.
I wish u sold the whole package. I would love to get,mt hands on 2 power walls to run my house. Good job.
Wyndmoor, PA
I know nothing about electric vehicles but I sure like watching your videos.
Man, would LOVE to be doing this with my weekends instead of fixing up my rental properties in the hood.....now if I can just make it similarly profitable. lol
stumbled upon your channel. Totally dig what you all are doing.
Came across your video by pure chance. Really liked the subject, and video itself was great! Keep up the good work! Liked and Sub-ed.
Thanks for showing this. A few thoughts: BMS isn't just a luxury or something you should use when you think your batteries might need levelizing, it's a safety measure to prevent overcharging and fires. Also, you get more smiles per photon when you use tech to massage your batteries, right, so a BMS should be a priority with BEVs, not a privilege. Just ask to fools who burned down their houses overcharging LiFePO4 hobby packs to power their ebikes. If I misunderstood, and you do have a BMS inline, I apologize for the tongue lashing.
Also, please don't fondle your high voltage electronics with your bare hands like he does in this video when it's hot. It's a bad habit to get into. You can point, without touching. Lastly, just because a solar installation isn't grid tied, it doesn't mean you don't need a permit and inspections. Lots of folks do stuff without a permit, but please be careful not to instruct other people that it wasn't required.
Elon musk may crash and burn, but they say hes got electric cars in the spotlight. Even if you do as well Jehu, Im sure you have inspired a lot of people with your videos. I think you've got the stuff of an engineer, a born engineer.
What you guy do is great! There should be many more of you out there.
FYi guys, I did the math on this when the powerwall was announced. A DIY, Rolls-Surrette, lead acid powerwall would cost less than half of the Tesla powerwall and last 4 times longer.
Of course, the batteries are much larger, but that's the only problem with it. I included a battery management system, as well as a power distribution system in the costing, so its a total system price.
Top of the line Lead Acid cannot be beaten for price per Amp Hour, per Year. The Batteries they use for the Tesla Powerwall will need to be replaced long, long before the Rolls-Surrettes will.
The only technology that can beat Lead Acid on a price/Amp Hour/Cycle Life comparison is, believe it or not, nickel/Iron batteries, as pioneered by Edison himself. Unfortunately they are not sold commercially. EDIT: I am wrong about this. They are sold commercially. And they are expensive.. which should tell you something about their longevity.Look up 'Edison battery'.
Timothy Zyg a
Timothy Zyg numbers? :)
A 700 CCA Yellowtop only produces 55 AH. V X A = W. 12V X 55AH = 660 WH. 33,000kwh / 660wh = 50 batteries.
Its not about Watt Hours. Its about Watt Hours *extracted* per cycle, per dollar expended on the battery. Do a spreadsheet incorporating cycle life and price and you'll see. And for those who don't believe me, it's 20 minutes of work on a spreadsheet to figure this out. Do the work and you'll see for yourself.
Deep cycle battery count needs to be > 100. Your cant discharge more than 50% or it has a very short lifetime.
love you guys for the detailed showcase, your efforts and enthusiasm in the EV & EV charging stuff. It is so cool to know that the era of oil-dictation is about to fall with no doubt and everyday we can work on the progress of improving our future. Greets from Germany (The part in Europe that unfortunately clings the most to the old world of fossil fueled cars) and keep up the good work Jehu and Michael :) !
Good luck trying to charge anything when you have smoke from any surrounding fires. we are off grid and had to run a gen-set to keep our fire sprinklers pressurized.
+Clarissa W how many fires do you expect?
all you need is 1
this is awsome. I would like to know what is the cost of a sistem like this and hoq many years the batteries are going to last.
Stop making *pop corns* in our ears.
Modified sine wave inverter 😂😂😂😂
Ugh, it's terrible, right? Knowing nothing about this, I'd assume that post-processing could invert the sounds at these frequencies and more-or-less kill this buzz. Somebody more informed can correct me, or confirm this.
Excellent video! Very inspiring! I was planning on waiting for the Tesla Powerwall to become available. Now that I've seen this, I don't know if I can wait. I also don't know if that's the solution that works best for me, knowing how much more kWh I would get using this setup than using the Tesla Powerwall. Got some serious thinking to do. I would love to see more on this!
Do it!
Man I wish I was smart enough to do this on my own. Maybe it is easy for people with the knowledge, and maybe it's a little fear mixed in. But I'd be scared of getting electrocuted, and just wasting money with trials and errors. Either way I'm dying for something like this. Hope I can find a guy like this when I get back home.
You're smart enough, there is just a huge amount of information and choices, so it tends to overload the brain, which causes one to want to hide in the bathroom a lot. Once you decide exactly what you want to do, and use it for, it gets a little less daunting. The hardest part is deciding on what kind of batteries you want to use. (I'm still wrestling with this) Just take your time, read and view posts, and follow the path it takes you. Hang in there.
Thanks! Your right. I found some simpler versions, and just started with the super basic one battery, and one solar panel. I fell more confident now. But like you said I just need to do the research. Hope you figure out what you want to use. Maybe make a video ;)
Mike Payne Mike, curious if you decided yet on a battery? ;)
No, not yet
You can start with a simple 12 V DC setup, perfectly safe to work with.
Great video, thanks for the info. Any tips to make this system even more efficient?
not any that are particularly attractive to me, but having panels follow the sun would increase efficiency.
so after this purchase, he pays nothing for powering his cars. brilliant.
Have you thought about coming up with a tesla power wall for a motorhome? When I look at the Tesla website you can pre-order a powerwall with around 13kwh in the 6k range - that's dirt cheap for that kind of storage. Combine that with solar charge controller and inverter and you'd have a killer RV off grid setup even allowing you to run a small air conditioner.
Very nice interview!
I could run my entire house with that system!!! My household average is 25KwH in summer and 30KwH in winter per day (In Canada). This is amazing!
Equivalent of 45 powerwalls so this is using used battery packs from Tesla cars?
Well they are using 18560 batteries, the same type as Tesla, but more of them.
Thanks for posting. Tesla/SolarCity said in their 2Q earnings conference call last week that they have considerable existing backlog in their ability to supply product for commercial storage demand. That's for commercial uses, as opposed to consumer or residential applications. I've seen rumors that Tesla already sold their entire 2016 production capability for storage, and have therefore, been unable to provide PowerWalls to the residential market in the USA. Hence, no PowerWalls available.

Great video and have watched many of yours and find that you are a genuine person that cares about sharing information when you find it. Thanks, also if you can do a short video on the components used and name them including where to buy them from it will help others create their power walls and put a little more pressure on the power companies to stop fucking around with the simplest of things and help the average person live a decent life without getting gouged every step of the way. Thank you and great job.
How far does your electric bus go on one charge?? Cool charging setup!
far
to me that just screams 60 miles lol
+xilw3r I've made like 50 videos on the eSamba guys, all kinds of detailed specs are available
53kWh so I assume 160 but probably more unless you're going high speeds with that brick body
Watch Jehu's Road Trip videos. There is not single number of miles. It all depends on a bunch of factors. But Enough to do a road trip.
you have compressor and 2 fan motors amp surge when the unit starts. measure it with a clamp on amp meter. try adding a hard start kit to the a/c unit. not sure how to size to a 120 v system. visit a hvac vendor store and ask them.
Very good job.
Great video. Thanks for sharing. This is exactly what I envision when I someday take my own grid-tied array off-grid.
this wall pack vs tesla wall pack is night and day. this is good and needs to monitored. tesla wall packs are maintenance free. plug and play
+Dave “Nifty Fox” NF on paper It sure looks like it, but you'd be surprise how low maintenance our wall is in practice
Nothing created by man is truly maintenance free because nothing he created is 100% perfect.
This makes me want to buy the tesla wall from elon musk. Elon musk is going to lead the way and the rest follow
Pretty good price on the tesla battery packs if they have the capacity they are rated at. Just couple of mistakes on the website I found. According to the datasheet the cell is 3.6v nominal and 2.7Ah rated capacity. So the capacity of the pack should be 59.4Ah, 3.2kWh. Nominal pack voltage should be 54V and not 57V.
Great vid bud
Makes me want to build my own... but I'd be going blind reading all teh technical stuff I'd have to to make the stuff safe... Still this is very cool stuff... subscribed!
It would be great to be "off the grid" but most cities won't allow you to be off the grid. How are we going to change if cities, townships, etc. won't allow this type of electrical independence?
I have off grid systems in over 40 states. You can put off grid power anywhere you want, you just have to do it with a professional system and the people who know how to do it correct. I can permit anywhere with my engineered designs.
Make some noise! Talk to your city zoning dept. They are human too!
Just don't pay your power bill, they will turn it off and you can just go off of your own power
not that easy in many cities its required by law that you are connected to the grid as a safety excuse or else you cannot live in your home legally
austin bevis & then you learn the house can be codemed for not conecting to the grid,but try it anyway.
Very informative with Array controller inverted scenario. Battery Bank clever. Good info.
click pops no problem, Skippy in the background got a little annoying. Overall nice job on the video.
Sustainability Rocks...
This was dam good info video 33kw thts insane
kwh i believe. still insane but different
kilo watt hour makes more sense kilowat is instantaneous power not total energy
pv abhilash - No, not 33kW. 33kWh. They are two entirely different things.
Very easy to do this for half the cost of the Tesla wall. DIYev.com is coming out with classes and kits soon. Get used batteries!! Good idea and cost effective. These guys are very informative. Good job.
go with edison batteries, they last 80 years and basically can't break.
Yes, I am currently trying to figure out how long the Li-ion battery's will last.
Panasonic suggest that their batteries (used in Tesla powerwall) wil degrade 25% after 500 cycles of 100% capacity (that's from 4.2V tot 3.0V)
At a Daily use, that's about 1.3 years.
You'd only been cycling them at 100% capacity if you're literally *trying* to degrade them as fast as you can. You wouldn't do that.
+roidroid That's how much I don't care, 20 years of life worse case why would you worry about degradation?
According to wiki, this battery has a charge/discharge efficiency of 35% of all the energy you put into the battery.
I love this video, but please explain how you installed a high power electrical system and you don't need a permit. Especially in California, I live in NJ and I don't think I could just install an electrical system in my house without having the town inspect it.
am I the only one that hears popping in the sound? Went to another video, no popping.
Otherwise, nice video.
interference
I'm hearing it too
This is excellent project !! Thanks for telling the cost, very nice !! I love it...That's why they don't want you to use and can't access that huge 40-60kW battery pack inside EV and go EV-to-House,because in combination with solar,that would be OFF grid for everyone !!!
the audio popping must be spikes in the power or something...
I find the dog squealing in the background more annoying.
Yeah, I complained and he shot back with a nasty remark. There is no place for that kind of background noise. It takes away from the message. Too bad!
Hey, two way street here, you going to be critical of my video, im going to be critical of your comments, This video contains tons of good info and you are going to concentrate on the background noise? you are a terrible viewer, show appreciation for the good or MOVE ALONG
really man? for someone who has some good content this was a terrible way to reply to concerns about audio being bad. I personally am 80% deaf and the pops were distracting. Just take the criticism to heart and test your audio next time. Humility always wins in the end.
A deaf person complaining about my sound? Seriously....... the problem is not your ears but my sound?
High Voltage Five!
Great job and kudos to both of you.
U guys are awesome!!
awesome video. Interesting no cut interview. felt like I was there. Miss you guys.
what Tesla need to do is add solar cells to the vehicles ruff
;-)
That would net you about 100ft more range each day wow totally not worth it
Acually I think this idea has potential - I was thinking about this for some time. I dont think this would be great for personal vehicles - although it wouldnt need to affect aerodynamics in any way. However, with anything bigger than that like trucks this is surely the future. It would help much more than 100ft.
Stefan can you add? No it would not help much more then 100ft
I think this "100 ft" argument is nonsense. Keep in mind that the panels would charge the battery all the time - not only while you drive.
This is super cool. I am surprised not more smaller companies do this. One question, when you have this system operational, how easy is this to tie into the grid? what restrictions will you have to deal with? and what device(s) will you need to get it connected?
Buy a Grid-Tie inverter ...
Dude. I have watched a couple of your videos. First I would like to say your so cute.
I have a request and a question. my request is can you make a video in girl language. like It all sounds so complicated. Perhaps just say like you need this and this and this and connect it to this and this and this. you can get it here and it costs this much and once it is set up all you have to do is this every so often.My question is based on my future plans for living off grid. I'm single and have no intention of having any future with a guy around to help me. so i need to know how to do stuff alone. I have ten acres in Florida and hope to convert a two-story tough shed into a tiny home for myself. would one wall run my house. There is no power or water access on this property so I have a lot of work cut out for me. I was also wondering if i would need to be connected to the grid with a wall. I'm hoping not as a power pole and such in its self is expensive.
No such thing as girl language. Get with the program and buy or borrow some easy books on electricity.
This is a really good. We need to think out of the box. When someone think out of the box and have have the courage to show it to the world only good things happen. Go ahead my friend and proof your concept.........Ahhhh... As I know... Those 48 volt smart ups's have to be programmed when you put fitter end batteries. Maybe that's the problem....
More good stuff.
Awesome video. These 18650 batteries...did you say they were used? If so, how do you know you have 15 years left in them?
Hold on. He said fire season?! Aint no way im living somewhere that has a fire season. Summer is hot enough without actual fire.
california has a very real fire season
Life under your rock seems simple 😂
It would be nice to get a complete schematic on this system for a off grid set up. you think you can make that happen.
Damn. 16 grand..... idk. Hard to justify
start small man , he spent 9000 on batteries .... if he didnt have those , he could still run things and charge his car ... only when the suns out ...
at least in the day your saving money then
As my 8 kW solar system generates way more than I consume, I requested to my utilities that the excess kWh be carried forward as a credit from month to month indefinitely until I terminate service. This means I don't sell my excess power, which I would only get 5 cents/kWh compared to the 10 cents/kWh that I pay. It's a better deal for me as long as I know I'm going to eventually use that excess kWh eventually. I know I will as I have an electric brewery that I use frequently during the winter. It's a better deal for my utilities as well, since they need the Renewable Energy Credits for government funding (I think).
30% Federal Income Tax deduction on all capital costs included? If not then $16k less 30% = $11.8k.
I'm guessing you don't charge an electric car as well as run your house? I'm still 'surrounding' the parameters (numbers) on a similar system to this video for our house. During AC season, we use 70 kwh per day, just for the house. Charging a car every 3rd day would add about 10 kwh/day more. We have numerous public charging stations and my wife charges at work, so those factors are nebulous. The sun shines 6 to 8 hours per day, almost every day. So we'd need a 70+10=80/7 hours = 11 kw system. But that's on paper. Ironically, the first problem is the system is too big for most of the year.
I've got it. We'll add a pool. A more practical answer is to reduce the size of everything but the battery pack (bigger is always better) and find energy reductions throughout the houses' design. There are lots of place to improve, such as isolating all this exterior stucco from the sun.
Plus you have to pay for the power to charge it, raising how much electricity you use. Just a worthless fad.
I apparently saw this video before... But why are you charging the car through an inverter? Wouldn't it be more efficient to charge with a DC charging unit thus skipping the inverter and whatever losses are incurred in the inverter? It seems redundant to invert DC to 220VAC and then back to whatever the charger wants in DC. Wouldn't it be better to just convert the wall DC to the DC voltage the charger needs? Can you not get a charger that can use DC as an input?
Nice, he just gave you credit for a smart idea that you had for a tool. Dude this is awesome, I'd love to work with you. I'm also struggling financially and it's tough man.
I know with a lot of UPS systems they require Batteries to make them work. Even when you plug them in and they do not power up they still need some kind of small load to make it happen. With my UPS even though the battery said needs to be replaced. When i unplug the Batteries from it the UPS doesn't power up at all.
You look like a mexican roman atwood
That is exactly what I thought lmfao
who's is roman anwood?
***** roman atwood big TH-camr lol. You are joking right?
you don't get it, do you...
who got what?
Very much appreciate this video, great information for stand alone off grid projects.
Live on top of a mountain with lots of wind, a waterfall and lots of sun.
this is neat! so is it basically a power generation/storage system for staying off the grid (in the case of power outages and for free energy)?
Depending on your electric bill you won't break even for at least ten years and we are not talking any maintenance.
+John Stephanites it's not for everyone, but it's really attractive for us Californians that pay top dollar for energy
I mean I love the idea and to actually get it set up where it worked would be very cool. I think that your 300 Tesla wall idea makes it much more doable. I think if you got the Harbor Freight Solar Panels it might look a little better as to the idea of worth it. Do you think it is a good idea to use Harbor Freight panels as to cost of other more reliable ones? Love the channel and Subbed by the way!
+John Stephanites harbor freight panels are not the best value, 45w for $149 Amazon has a 100w panel for $112 and you can get $30 charge controller. More than double the wattage for same price
that's how it all works, ever diminishing return means it might take longer, this is modern day snake oil salesmen trying to make you think it will pay for itself in 10 years, in reality it will be 15-20 but it wont hast half that. Think how many people's vaporizer batteries are exploding, imagine these doing that after 5 years and them blaming you for bad charging practices.
+Obi Wan Cannabi can you please stop spewing stupidity, some people reading these comments might be fooled
Dope setup... wouldn't it be better to use Double 00 Gauge wire for the lead wires from the batteries? He did say they get hot sometimes...
Just finished my version of the same imgur.com/gallery/IFdCC
Amazing setup. I know it's been 9 months, so you may not see this question. If you do, dont suppose you could share details of where you got the batteries (make/model) and other components you used? I am in Australia and very keen to get into this type of battery technology for a home project.
These particular batteries were probably made is a limited quantity. I don't know if it is possible to get more, but they were purchased here. evbatterycenter.com. The Tesla 24v packs. I don't think getting them to Australia would be cost effective. Best to find out which electric car is most popular in AUS and find batteries from that model. The solar equipment you can't see in picture is all off the shelf stuff from Schneider Electric Solar. Bus bars and cables to connect the batteries were all custom made.
You need to get into RV. think about a min home with with a pair of 24 volt alternators rated at 300 amp each just going to waste. this is not the hole story it only gets more compelling. love your channel.

lmao
It's just one of those dogs that everybody WANTS to skin alive because it won't shut up!

Jehu
I absolutely love your work and vids. Its all very enriching. Would like to know if you can offer some help in my project?
I have a used 2011 Prius battery that I pulled out of my Prius and wanted to know after I recondition this. If I can somehow use this for my power wall. If so, what would I need to complete this project with all needed parts to power my 1000 watt air conditioner and possibly a few lights for now with the possibility for expansion. Thank you very much in advance.
I forgot how irritating dogs are
Very good video and also thank you for the parts list this will serve for my diy solar system as I buy my home
Can you put a muzzle on the dog--very annoying!
Lol I support the dog.
Ok, I was a bit insensitive. It's not the dog's fault, LOL. Sorry 'bout that!
All new homes should come with this tech.
Anyone who thinks this in any way "sustainable" simply does not understand the word "sustainable." There is nothing sustainable about this. Worse, it is not scalable. These type of projects are causing people to go down this road of unsustainable "solutions."
dosmastrify This is the internet, anyone can say anything, no explanation or facts needed.
+dosmastrinfy Can everyone do this? More importantly, can we run the interstate highway system using this? It might be useful for individuals, it might make sense for the guy in the video, but this can't be done at scale. Electric vehicles are simply not going to replace diesel and petrol engines. There is zero evidence showing that PVs are net energy generators. Go look for it, you simply cannot find it.
+tarstarkusz Here are more opinions, everyone knows opinions are better than facts.
+dosmstrify There is no evidence to support that PV panels generate more energy than it took to create them in the first place (energy returned on energy invested or EROI). The best studies show energy consumption across the production process, but none of them take all of the embedded energy into consideration. Specifically they leave out the energy needed to create the supply chain (bulldozers, factories, trucks, boats etc) along with the highly technical civilization needed to make all this possible. Even the most optimistic looks at PV shows relatively low EROI, especially when it is compared to oil. This might seem like nitpicking, but it really isn't. We have a "budget" of energy we can use in the next 30 years if we want to avoid the worst of climate change (for example). We can blow this energy any way we want. If we spend this "budget" on alternatives that turn out not to be large net energy producers (at least 15x), we will have have squandered this budget. It is not at all clear to me that PV and batteries are a good solution.
+ehgarcia Do I have to post citations for gravity? Would you mind telling me what specific thing I said you would like to have data about.
Don't you need a permit for any modification to a building. You have panels on roof and electrical wiring. You need to get a electrical permit from the city of Los Angeles (building and safety), and a permit from LADWP to connect to the grid. You would still need city permit.
no
First off he's not in the city of Los Angeles. There's more but I'm not going to bother telling you about it
im curious how they test those used batteries. 3000 charges is about the best your going to get out of 18650's that are new and as far as i know u cant really test for how many charge cycles its gone through. a curious technology that might work great with a large array is the tech in SSD's. they do interesting stuff to try and spread the load around reducing read write cycles and increasing the lifecycle of its ram, or if used in this, a battery. would require a large oversized array though.
Been toying with this idea, we don't get enough sun in winter to live off solar, but could still charge battery at night with hydro then run off it all day during on peak, while solar adds a bit of power for a few hours. In the summer months solar would provide most of the power. I don't have much room on my roof though, so I'd only be able to do like 1-2kw at most. But that part of the roof faces south so that's a bonus. (other areas get shade from trees)
I see that you have used 33kw of battery pack. How much time it would take to fully charge your battery pack using 2kw solar panel?
where can i get an electric motor? you make it look so easy and fun.
Great and helpful video. Thanx for the time you spent making it.
Hi there,
If this happens to be written in poor English, I apologize. I'm from The Netherlands.
I was wondering for what reason your UPS system isn't working. I bought myself a used APC UPS (about 5 kW real sine), but I haven't tested it yet. So please explain.
About the Tesla Powerwall. I don't think it is very useful, for it can only drain 2 kW max. So having 7 or 10 kW sounds great, but you'll find the bottleneck at the level of the inverter.
Looking forward to hearing from you.
Best regards, Roelof
Would you use this system to power your house 100% as well? Like Running HVAC, TV's, Fridge, Lights?
Or is this just limited to charging EV Cars
Intersting. looked up the Tesla Powerwall recommended for my size house.
It says 2 reccommended and the cost is $12,500 not counting install costs which they estimate at $800 to $2000. So the price of the wall in this video is pretty damn competitive.
