I Installed Solar panels two years ago, then install two Tesla Powerwall 2 batteries last year and this year bought a Tesla EV Model 3 LR. Got all the Tax rebates for everyone of the items above. At home I only use solar to charge my batteries and EV. The only carbon I am producing now is when I breath out. Sold Tesla stock to pay for all of this. Then went on a trip through the Midwest and East coast with my new EV. Drove over 4000 miles, no problems charging up at any time. Electrification is the way to go. Will lower lower gas prices in the short term. Love driving my EV, faster than most cars on the road and safer.
I have 2 PW2's installed in 2018 to complement our 13.2 kW solar PV system installed in 2012. Love them and the charge on solar feature in my PW2's. I paid $15k (US) for my two Powerwalls. The output from my PW2's has been more than sufficient for our use and have been very satisfied with their performance over past 6 years, so the extra output feature maximum in PW3's is not needed by us. We effectively charge our two EVs (Tesla's) off our solar + battery system and export ~half of our excess solar back to grid via net metering.
I just got two Powerwall 3s installed in Southern California in the US. I had two separate solar systems with one having micro inverters and the other having a string inverter. Removed all those inverters and just using the ones in the PW3s split into 5 strings. Didn't need the gateway as we have the Tesla Backup Switch available here. Much simpler installation. The Tesla app is fine but I would like it to show the solar generation based on strings since I lost the per panel monitoring of my old systems. Also it just shows the percentage charge of the batteries as one number, show hard to tell if something is going one with one. So far over a month and a half of brutal heat, the system is working well and I'm able to cool the house better during the day and make it most of the way through the peak TOU period and not pay the utility the exorbitant rate for most of it, plus the software learns this and pumps some battery power into the the grid to give me credits to offset that. Haven't had an outage yet other than just testing it out. Will probably add more panels and add-on batteries next year when we are getting electric vehicle(s).
I have a Tesla Powerwall 2 and this enabled me to shift my house load that was around 25% night rate, to near 90% night rate for the year, combined with my 7.56kWh solar. it has also saved me a lot of money with me being able to use more solar without buying it from the grid.
I think PowerShare/bidirectional charging with an EV could be the game changer for Powerwall 3. if they open this up to enable non Tesla Evs then this could be stacked with all evs capable of VTL and then be able to use the much larger car battery to supplement the PW3. If they limit this to Tesla vehicles only (currently only the cyber truck) this will be a big missed opportunity imo.
totally agree, but none of these reviewers seem to mention this, going on and on about all the features but failing to mention any issues you may have down the track. Much easier to pull a standalone inverter off the wall and replace than to mess with an integrated solution. You can be guaranteed that in 5-10y years or however long it is down the track when the inverters start having faults that Tesla and the solar industry will have moved on to the latest and greatest tech and you might even need to replace the whole unit. Do you remember those integrated TV's and DVD/VCR units. They didnt age well.
100%, I’m still in the camp of modular , although I admit I do fancy Franklin power pack though. Better output and scale , depending on your application
We are in the process of having two PW2s installed with our existing Ehphase AC-coupled PV system. Local Tesla authorized installer doing it for $15K. If I can't get a V2H EV next year we might add two more PW2s next year.
I have a battery, and even I think it does not make economic sense for most situations (not yet at least). Luckily my Franklin battery was quite cheap when i got it, and I also got a rebate - so the price was only $7k after installation (for our friends in the US, that's about $4,745 USD). The reality is though, for the battery to pay for itself, it needs to offset a lot of high peak power usage, and you would need to use the battery to its full extent every night for it to start to make sense. If we use the PW3 as an example, that's 13.5kw/h of power * (peak power cost - FIT) if you charge from solar during the day. For me that would be 13.5 x ($0.53 - FIT). My FIT is now just $0.03, so if every night I maxed out my savings, a PW3 would save $6.75 (absolute best case scenario). If a PW3 was $15,000 installed, that's about 6 years until it is paid back. However, this best case scenario is not that realistic, as most people will not use the 13kw during the peak time of 4:00pm to 9:00pm. At 9:00pm, my tariff for example falls to about $0.34 per kw, then at midnight, the tariff falls again to $0.08. So the return on investment now decreases. Most users will also keep a buffer of about 1.5kw in case of blackouts. For me, we are pretty power hungry, but I often find my battery is down to about 50% by 9:00pm, then down to about 35% by midnight, with nothing left by 6:00am. Running on those average figures, (6 * ($0.53-$0.03)) + (2 * ($0.34-$0.03)) + (2.5 * ($0.05-$0.03)) = $3.745 = about 11 years to pay for itself. This is much closer to the expected scenario, as it's my average use. To be fair, the battery will likely still have a lot of life in it after 11 years, and electricity will go up in price; though that is $15,000 that was not invested over an 11 year period. Now, i could charge my car from the battery, but I would more than likely charge during the day when power is only worth $0.03 (money lost from not selling it to the grid). I could charge my car after midnight (which is the whole point of my EV plan), or i can charge from 11:00am to 2:00pm for free during the day on my current plan with OVO energy). The point is, the battey does take a long time to pay off, will take longer if the battery did not charge during the day because of poor weather, I go away on holidays and don't use the power, or i simply don't use that much each night.
Or in my case, I get a 50 cent solar feed in tariff, and buy back electricity for 38 cents at any time. Cheaper to buy electricity after ive exported my solar. And its been like that since 2010 for me. Straya - shit yeh!
@@superwag634 ah, the Solar Bonus Scheme - 44c on top of the FIT. I used to have that back when I had a 3Kw system many years ago. Try to run nothing during the day to feed as much electricity to the grid. Hold off getting a smart meter as long as you can.
@@xiaowei1 exactly. Everything off during day and then crank everything on after sunset and pull that peak priced power everyone hates paying. I’m sure they’ve been losing money on me as I haven’t had a bill since 2010 🤷♂️
Any insights into when bidirectional charging will be enabled? Without it I can’t justify either a powerwall or an Ev. With it I would use the ev (hopefully a geeky e5) to help power the house in conjunction with the battery overnight whilst aircon is running. We generate plenty of surplus solar each day and work from home so don’t drive much
Thank you for the information . I have two Powerwall threes. They’re working beautiful. I guess if one fails the other one takes over and everything will operate normally. I wonder if the Tesla app will notify me of a malfunction. Planning on getting two extender powerwall 3s. I will have plenty of power for power outages.. At least I’m getting some payback versus having a back up generator. Hopefully in the future time of day metering, you can optimize your payback with the power wall three.
I think you mean 11.04kW and the 185 is rma rotor motor amps...it's not the same. Also ac coupling existing inverters have to be limited to 5kW max ac. But yes overall much advantage
Batteries & solar make the most sense on a ToU (EV plan) & a still prefer to charge my EV on that very inexpensive 8c overnight rate, typically 12-6am.One of the uses when the battery makes sense is to use this instead of the very expensive peak tariff on the same ToU plan, atypically from 4pm-8pm weekdays. And or on the still relatively expensive shoulder tariffs. The last thing I would use it for is EV charging.
Finally the Solar problems and issues cropping up here as well. I keep commenting it for a while 😄Inverters usually cannot work without grid (off-grid) mode is even illegal in some countries. Battery backup for your house also not as simple as these videos suggesting... Battery has max output if you overdraw electricity it will burn down. And distributed systems also not that simple. Electric companies moving slowly, legislation is slow, acquiring meters is slow. And when you sell your extra electricity they pay you 1/8, or 1/10-th...
your post is full of misinformation. Nothing burns if you overdraw - it just cuts out. Inverters with islanding feature do work off grid and all that is needed is a proper automatic switch at switchboard when power goes out. Noone forces you to sell your electricity. Set inverter to zero export if you dont want to sell.
@@superwag634 Not sure what is the misinformation. But let see the points: . - Electric cars also should not burn out but few times they do. Overdrawing power for long period of time generates heat which causing the fire in the cells. No guaranty there is protection against it in the battery pack. Tesla power wall, I'm sure has it, but not everyone pays for that price. There are cheaper packs, or used electric car old packs installed, with less safety features. Price is price... - I also wrote: "inverters usually not working without grid" those are the cheaper versions. If you pay high end inverters those off course can work, BUT it is in many country ILLEGAL... So even if the inverter support that you cannot configure it to work. Unfortunately in Hungary it is also illegal, like balcony solar is also illegal... I have my original small system 1.2kW Vevor "simple" inverter it is not doing anything without Grid. New system have 5kW Huawei inverter it is supporting off-grid, but as mentioned Illegal. So not configured like that. - I buy electricity off peak 37 HUF, and 67 HUF at peak. But selling it fix fixes 5 HUF. That is 7-13x difference... If I turn out the access energy export I get 0... All extra produced energy going to be wasted! Why makes it my statement false? Earning 0 how changing the basics of mathematics, such as 67/5=13.4 difference in price?? So what was exactly the misinformation there?
@@superwag634 Just to show my point with battery fire. th-cam.com/video/-KvssGZy6js/w-d-xo.html So tons of people using refurbished electric packs. Software and heap pump for cooling system is the crashed car... So not much protection. But to be honest those packs has tons of "juice" so they more likely can support, induction cooking + micro+ TV+tons of other things running parallel.. So it can be much safer then a cheaper house purpose backup battery. Which still lots of people have with grid backup they work fine. But off grid mode they can output very limited power compared to a house requirements.
@@tothimre7950 well I have 2 x 7kw systems. One is over 14 years old and still going. Second is 3 years old. The battery thing, well I live in Australia and it is completely illegal to do anything with scrap car batteries. It’s only commercial certified backup batteries and they need approval for connection to grid and installation by licensed electrician. They indeed back up the whole house if grid power goes down. Nothing illegal there. In terms of export, they’re now starting charging us for exporting power during day. 1-2 cents per kWh. Unless it’s in the late afternoon, when they pay you up to 10c per kWh for solar export. Buying power from grid is about 50c per kWh. Most of the country has smart meters with computerised time of use data capture and it sends that data to electricity company every 30 minutes. If you export a lot of solar, you get a bill for that nowadays. The power is basically worthless and there’s too much of it, which causes gas turbines and coal power stations to need to be shut down and that’s not good for grid stability. So there’s not any fire issues with house batteries. I don’t even remember the last time it happened here. Cars yes, they burn in peoples garages and driveways. Back up power from battery is in no way illegal. And exporting power can cost us, so you can program inverter not to export.
@@superwag634 Thanks for the reply. Interesting info. However I think none of this makes my original comment misleading. Actually you are even confirming points, you wrote electricity price is 50C and they buying it from you at 1-10C... so huge difference there also. Electric Companies don't want you to make money and for me registering the whole system thing took 4 moths as I wrote it is slow... And government like taxing everything here the 5 HUF is also taxable with 15%. At least some income after the expensive investment. For me without battery it was 1.5USD per Watt, with battery is 2.5 USD with all Chinese parts. In In Australia probably cheaper, China is closer probably much less taxes. Hungary sucks we have world leading 27% VAT, etc... But again turning off "export" and just let electricity wasting if battery all full, still the worst option, minimum income better than 0. I think worldwide regulations are similar for some extend. Like here we also must have Smart meter, and only registered electrician can build the system. So they know the rules also. In Hungary off-grid is illegal. The electrician told me and also my LUNA2000 10kw pack has 5kW max output. Which is OK, but can reached with electric oven 2.2 kW and induction plate 6-7kW, etc... Problem with battery backup you potentially don't realize there is a grid outage and you keep running appliances! So even if it would be legal to use it off-grid still not recommended. My pack is only for night and "dark days" usage with grid support.. I have this battery which is commercial, no scrap, etc.. Look at the spec: solar.huawei.com/en/professionals/all-products/LUNA2000-5-10-15-S0/specs "Max. output power" is the important not the PEAK which is for 10sec. So these batteries output power is usually 1/2 or 1/3 of the original capacity. 2-3kW is easily reached with 1 water cattle 2.2kW + micro 900W and you overdrawing the battery. And if you have not so smart pack then it will burn. Anyway I think we reached a conclusion what was my original point. These videos makes solar "simple as stick"... "click, click and all ready to go, no Grid needed you are independent, you make tons of money, etc.. Take a loan even otherwise you idiot..." Truth is not that simple. There are 1000s of different devices with different capabilities. Tons of different regulations per countries. So if you allowed and buying the right parts then you can achieve all mentioned functionality. Otherwise not... And price will be massively different based on the components you buy! Return rate is also differs, but probably it won't pay off in 20 years.
Battery storage is still way to expensive If you had 1 and used all 10 kw every night of the year I pay 30 cents off peak So around 3 dollars per day or around 1100 dollars per year 10 years is a return of 11,000 for something that cost 12 to 14k Might as well put the money in the bank a get interest it would be a better return BTW I am not anti solar I have 20 kw but I cannot make the cost numbers for a battery to add up to any savings
Did you factor in inflation? Future carbon tax penalties? Unfortunately any energy grid running on coal, gas or recycled industrial waste will face additional taxes in the near future. Regardless of the steep costs at today’s prices for going solar, it’s only a matter of time before traditional supplies become stigmatised by western governments. It’s already happening in the UK, although their current Prime Minister is a deluded dictator.
Your calculations are based on current energy rates. In the UK at least the rates don’t stay static for 10 years. Then there is the convenience of should there be an outage you have the back up power supply. Also what about charging at cheaper rates and exporting at higher rates in the day?
I paid 12K$ for 50KWh from China.Charging a Car from a 12K$ battery with just 13KWh is useless ( my car typically takes 20KWh when I come home) and by the way my 50KWh battery would be able to deliver 50KW! I am only limitted to 15KW by my 3 phase Inverter.All in all I think this is just an overpriced toy 😂
What are you talking about? Who would charge their car through a battery? Your alleged 50kw battery will be 50kw for 6 months. It 2 years it will be 25kw.
I can justify using a car in place of a power wall, and adding some of the price into the car to offset the eventual cost of battery replacement. If the car is a plug in hybrid, I would have the car as a generator in an emergency. Maybe in a few years I could afford a power wall to go with the inverter portion of the system.
Battery and a TOU tariff means you could make it worth without even needing solar. I only use 10kw or so a day so could just charge for free during the day
What am i missing? A 2nd hand tesla p85 with 90% battery is 15k. No battery and sold for parts is 4k. So lets say that 4k pays for inverter and case. Ive got over 75++kwh, from tesla, 15k. And that battery designed to accelerate a 2 tonne car to 100kph in 5 seconds. There is no way my combined household appliances pulls anything like that. Clearly im missing something, but just dont know what.
Way too expensive. Our all in one battery made in Finland costs 16000€ with 70kWh battery and 12kW inverter. You can connect 15.5kW of pv panels in two strings and support smart charging by reading the spot electric price a day ahead. Our company is named Heliostorage.😊
My household has a 8KW solar system. currently feeding power to the house and excess goes to the grid but our utility company doesn't pay us for the feed. My dad ordered the Tesla Powerwall not sure what model he ordered I think its the powerwall 2. Having the powerwall battery will that shave our electricity bill during both day and night?
Forecasters are warning that “dangerous heat and humidity” will spread across the central and eastern United States this week, threatening to break records for high temperatures and ending a spell of fall-like weather. The heat wave will bring unusually hot temperatures to the Upper Midwest and Mid-Atlantic, said a meteorologist at the Weather Prediction Center. The EXTREME heat and humidity could make it feel like 106 to 117 degrees Fahrenheit in parts of the country. In some places in the Midwest, it could be the hottest temperatures they’ve seen in many years, perhaps ever. Not only is it late, it’s the HOTTEST, too. So that’s EXTREMELY unusual. Columbus, Ohio, and Chicago are expected to reach a high of 97 on Monday. Louisville, Ky., is expected to hit a high of 101 on Wednesday and Thursday, while Washington could register 101+ on Wednesday. Excessive heat warnings are issued within 12 hours of “extremely dangerous heat conditions,” which means the daytime heat index feels like 105 for at least two days and the low temperature does not drop below 75. HOW'S YOUR HOAX TREATING YOU?
Thanks for the video. You did not mention that the capacity of a Powerwall 3 is 13.5 kWh; so with only one, it may not be able to charge your car for much more than an hour.
The current Tesla 3 has an inbuilt inverter. You mention that next year there will be one that does not have the built in inverter. Is that one going to be able to be installed linked to my current inverter? If getting the current one, that would make my current inverter redundant or as you say, the inverter in the 3 redundant and you are paying for that.
In Thailand Tesla power walls are priced at B699,000. That is around US$20,000.00. Until these power walls fall in price considerably the take up rate in south east Asia will remain low. Thailand is washed with sunlight daily. The whole country could run on batteries and solar. It’s such a waste that this issue is not being addressed.
good video. any more news on the smaller power wall 3 coming in 2025? None of the suppliers I speak to know about this. I am looking to buy two power walls but I might wait to buy the second one in 2025 (assuming installation costs do not outweigh the saving of the power wall.).
Hi Sam, what about a BYD home battery, seems like a great alternative to the Tesla battery at I think half the price, and I think its also a LFP battery, tell me what you think, regards Andrew
The retail prices for batteries are still ~$1000 per KWHr compared to the raw battery prices of ~$100 per KWHr - the industry has a lot of maturing to do, and as usual we have to get the government out of the way.
Hi, my understanding is that the only limiting factor to the powerwall 3 is the inverters 5KW charging. Therefore if your panels are producing 15kWhr of power, the inverter will charge at 5kWhr to the battery and the remaining 10kWhr will go to the grid. Does anyone think I'm not correct on this? I'm surprised it doesn't have a 10kW inverter.

Stuff Tesla as a green solution .. i would love a Tesla battery system but these guys charge way tooo much .. to pay Musk's 40 billion dollar bonuses .. bring on a BYD competitor etc for $5 or 6k and then we have a truly green solution that makes solar pay itself of ..
If you have an EV which has V2H where will you get power to Charge your EV. For a domestic home set up I do not believe an EV with V2H will benefit the householder except in a power outage

Finally the Solar problems and issues cropping up here as well. I keep commenting it for a while 😄Inverters usually cannot work without grid (off-grid) mode is even illegal in some countries. Battery backup for your house also not as simple as these videos suggesting... Battery has max output if you overdraw electricity it will burn down. And distributed systems also not that simple. Electric companies moving slowly, legislation is slow, acquiring meters is slow. And when you sell your extra electricity they pay you 1/8, or 1/10-th...
your post is full of misinformation. Nothing burns if you overdraw - it just cuts out. Inverters with islanding feature do work off grid and all that is needed is a proper automatic switch at switchboard when power goes out. Noone forces you to sell your electricity. Set inverter to zero export if you dont want to sell.
@@superwag634 Not sure what is the misinformation. But let see the points:
.
- Electric cars also should not burn out but few times they do. Overdrawing power for long period of time generates heat which causing the fire in the cells. No guaranty there is protection against it in the battery pack. Tesla power wall, I'm sure has it, but not everyone pays for that price. There are cheaper packs, or used electric car old packs installed, with less safety features. Price is price...
- I also wrote: "inverters usually not working without grid" those are the cheaper versions. If you pay high end inverters those off course can work, BUT it is in many country ILLEGAL... So even if the inverter support that you cannot configure it to work. Unfortunately in Hungary it is also illegal, like balcony solar is also illegal... I have my original small system 1.2kW Vevor "simple" inverter it is not doing anything without Grid. New system have 5kW Huawei inverter it is supporting off-grid, but as mentioned Illegal. So not configured like that.
- I buy electricity off peak 37 HUF, and 67 HUF at peak. But selling it fix fixes 5 HUF. That is 7-13x difference... If I turn out the access energy export I get 0... All extra produced energy going to be wasted! Why makes it my statement false? Earning 0 how changing the basics of mathematics, such as 67/5=13.4 difference in price??
So what was exactly the misinformation there?
@@superwag634 Just to show my point with battery fire. th-cam.com/video/-KvssGZy6js/w-d-xo.html So tons of people using refurbished electric packs. Software and heap pump for cooling system is the crashed car... So not much protection. But to be honest those packs has tons of "juice" so they more likely can support, induction cooking + micro+ TV+tons of other things running parallel.. So it can be much safer then a cheaper house purpose backup battery.
Which still lots of people have with grid backup they work fine. But off grid mode they can output very limited power compared to a house requirements.
@@tothimre7950 well I have 2 x 7kw systems. One is over 14 years old and still going. Second is 3 years old.
The battery thing, well I live in Australia and it is completely illegal to do anything with scrap car batteries. It’s only commercial certified backup batteries and they need approval for connection to grid and installation by licensed electrician. They indeed back up the whole house if grid power goes down. Nothing illegal there.
In terms of export, they’re now starting charging us for exporting power during day. 1-2 cents per kWh. Unless it’s in the late afternoon, when they pay you up to 10c per kWh for solar export. Buying power from grid is about 50c per kWh. Most of the country has smart meters with computerised time of use data capture and it sends that data to electricity company every 30 minutes. If you export a lot of solar, you get a bill for that nowadays. The power is basically worthless and there’s too much of it, which causes gas turbines and coal power stations to need to be shut down and that’s not good for grid stability.
So there’s not any fire issues with house batteries. I don’t even remember the last time it happened here. Cars yes, they burn in peoples garages and driveways. Back up power from battery is in no way illegal. And exporting power can cost us, so you can program inverter not to export.
@@superwag634 Thanks for the reply. Interesting info. However I think none of this makes my original comment misleading. Actually you are even confirming points, you wrote electricity price is 50C and they buying it from you at 1-10C... so huge difference there also. Electric Companies don't want you to make money and for me registering the whole system thing took 4 moths as I wrote it is slow... And government like taxing everything here the 5 HUF is also taxable with 15%. At least some income after the expensive investment. For me without battery it was 1.5USD per Watt, with battery is 2.5 USD with all Chinese parts. In In Australia probably cheaper, China is closer probably much less taxes. Hungary sucks we have world leading 27% VAT, etc...
But again turning off "export" and just let electricity wasting if battery all full, still the worst option, minimum income better than 0.
I think worldwide regulations are similar for some extend. Like here we also must have Smart meter, and only registered electrician can build the system. So they know the rules also. In Hungary off-grid is illegal. The electrician told me and also my LUNA2000 10kw pack has 5kW max output. Which is OK, but can reached with electric oven 2.2 kW and induction plate 6-7kW, etc... Problem with battery backup you potentially don't realize there is a grid outage and you keep running appliances! So even if it would be legal to use it off-grid still not recommended. My pack is only for night and "dark days" usage with grid support..
I have this battery which is commercial, no scrap, etc.. Look at the spec: solar.huawei.com/en/professionals/all-products/LUNA2000-5-10-15-S0/specs
"Max. output power" is the important not the PEAK which is for 10sec. So these batteries output power is usually 1/2 or 1/3 of the original capacity. 2-3kW is easily reached with 1 water cattle 2.2kW + micro 900W and you overdrawing the battery. And if you have not so smart pack then it will burn.
Anyway I think we reached a conclusion what was my original point. These videos makes solar "simple as stick"...
"click, click and all ready to go, no Grid needed you are independent, you make tons of money, etc.. Take a loan even otherwise you idiot..."
Truth is not that simple. There are 1000s of different devices with different capabilities. Tons of different regulations per countries. So if you allowed and buying the right parts then you can achieve all mentioned functionality. Otherwise not... And price will be massively different based on the components you buy! Return rate is also differs, but probably it won't pay off in 20 years.
Battery storage is still way to expensive
If you had 1 and used all 10 kw every night of the year
I pay 30 cents off peak
So around 3 dollars per day or around 1100 dollars per year
10 years is a return of 11,000 for something that cost 12 to 14k
Might as well put the money in the bank a get interest it would be a better return
BTW I am not anti solar I have 20 kw but I cannot make the cost numbers for a battery to add up to any savings
Did you factor in inflation? Future carbon tax penalties? Unfortunately any energy grid running on coal, gas or recycled industrial waste will face additional taxes in the near future. Regardless of the steep costs at today’s prices for going solar, it’s only a matter of time before traditional supplies become stigmatised by western governments. It’s already happening in the UK, although their current Prime Minister is a deluded dictator.
Your calculations are based on current energy rates. In the UK at least the rates don’t stay static for 10 years. Then there is the convenience of should there be an outage you have the back up power supply. Also what about charging at cheaper rates and exporting at higher rates in the day?
@@danfrench2008 still not worth buying at the current time
@@steveclancy7832 based on what…your calcs that aren’t complete?
@@danfrench2008 it's complete enough to show battery storage is not viable at the moment
THX SAM FOR THE UPDATE 🤗💚💚💚
I paid 12K$ for 50KWh from China.Charging a Car from a 12K$ battery with just 13KWh is useless ( my car typically takes 20KWh when I come home) and by the way my 50KWh battery would be able to deliver 50KW! I am only limitted to 15KW by my 3 phase Inverter.All in all I think this is just an overpriced toy 😂
Agreed. I crunched the numbers an they make no sense.
Overlooking the software.
Correct....batteries will never make sense.... particularly when we can get V to G and V to H
Which battery do you have and does it work to buy and sell electricity with Amber?
What are you talking about? Who would charge their car through a battery? Your alleged 50kw battery will be 50kw for 6 months. It 2 years it will be 25kw.
I can justify using a car in place of a power wall, and adding some of the price into the car to offset the eventual cost of battery replacement. If the car is a plug in hybrid, I would have the car as a generator in an emergency. Maybe in a few years I could afford a power wall to go with the inverter portion of the system.
Its the retailer used that aks. A battery worthwhile or not
Amber Electric offers the best arbitrage.
A friend has made anout $1700 since March
That's the same amount as a friend of ours has achieved since April.
Battery and a TOU tariff means you could make it worth without even needing solar. I only use 10kw or so a day so could just charge for free during the day
Sam you have 26kW Solar system 😮holly molly are you living in Walt Disney castle 😄it requires a huge roof.... Average home solar systems are 4-7kW
V->H and LFP=Best value proposition
What am i missing? A 2nd hand tesla p85 with 90% battery is 15k. No battery and sold for parts is 4k. So lets say that 4k pays for inverter and case. Ive got over 75++kwh, from tesla, 15k. And that battery designed to accelerate a 2 tonne car to 100kph in 5 seconds. There is no way my combined household appliances pulls anything like that. Clearly im missing something, but just dont know what.
That's garbage mate.
I just looked it up and the p85d is $53, 500 (2015 model)
Way too expensive. Our all in one battery made in Finland costs 16000€ with 70kWh battery and 12kW inverter. You can connect 15.5kW of pv panels in two strings and support smart charging by reading the spot electric price a day ahead. Our company is named Heliostorage.😊
My household has a 8KW solar system. currently feeding power to the house and excess goes to the grid but our utility company doesn't pay us for the feed. My dad ordered the Tesla Powerwall not sure what model he ordered I think its the powerwall 2. Having the powerwall battery will that shave our electricity bill during both day and night?
Forecasters are warning that “dangerous heat and humidity” will spread across the central and eastern United States this week, threatening to break records for high temperatures and ending a spell of fall-like weather. The heat wave will bring unusually hot temperatures to the Upper Midwest and Mid-Atlantic, said a meteorologist at the Weather Prediction Center.
The EXTREME heat and humidity could make it feel like 106 to 117 degrees Fahrenheit in parts of the country. In some places in the Midwest, it could be the hottest temperatures they’ve seen in many years, perhaps ever. Not only is it late, it’s the HOTTEST, too. So that’s EXTREMELY unusual. Columbus, Ohio, and Chicago are expected to reach a high of 97 on Monday. Louisville, Ky., is expected to hit a high of 101 on Wednesday and Thursday, while Washington could register 101+ on Wednesday. Excessive heat warnings are issued within 12 hours of “extremely dangerous heat conditions,” which means the daytime heat index feels like 105 for at least two days and the low temperature does not drop below 75. HOW'S YOUR HOAX TREATING YOU?

Farenheit? What is that? Oh, some archaic measurement system used in a dinosaur country.
@@rogerphelps9939 It's what they use in the GREATEST COUNTRY ON EARTH, THE ONE IN MY COMMENT. Seek medical attention.
Thanks for the video. You did not mention that the capacity of a Powerwall 3 is 13.5 kWh; so with only one, it may not be able to charge your car for much more than an hour.
Yes. A complete waste of time, and overpriced at that.
I think it's more the combination with the Tesla charger to do charge from solar only
The current Tesla 3 has an inbuilt inverter. You mention that next year there will be one that does not have the built in inverter. Is that one going to be able to be installed linked to my current inverter? If getting the current one, that would make my current inverter redundant or as you say, the inverter in the 3 redundant and you are paying for that.
Smart meter like import export meter ?
In Thailand Tesla power walls are priced at B699,000. That is around US$20,000.00. Until these power walls fall in price considerably the take up rate in south east Asia will remain low. Thailand is washed with sunlight daily. The whole country could run on batteries and solar. It’s such a waste that this issue is not being addressed.
good video. any more news on the smaller power wall 3 coming in 2025? None of the suppliers I speak to know about this. I am looking to buy two power walls but I might wait to buy the second one in 2025 (assuming installation costs do not outweigh the saving of the power wall.).
what do you think about exro cell driver ? will it be better than tesla powerwall ?
Hi Sam, what about a BYD home battery, seems like a great alternative to the Tesla battery at I think half the price, and I think its also a LFP battery, tell me what you think, regards Andrew
The retail prices for batteries are still ~$1000 per KWHr compared to the raw battery prices of ~$100 per KWHr - the industry has a lot of maturing to do, and as usual we have to get the government out of the way.
Hi, my understanding is that the only limiting factor to the powerwall 3 is the inverters 5KW charging. Therefore if your panels are producing 15kWhr of power, the inverter will charge at 5kWhr to the battery and the remaining 10kWhr will go to the grid. Does anyone think I'm not correct on this? I'm surprised it doesn't have a 10kW inverter.
You're not correct. PW3 has a 10kw inverter.
My Powerwall is saving me about $700 per year and i paid $16,000. Payback about 23 years. Not enough storage to charge the car in any meaningful way
As I have a Tesla Powerwall 2 and I was thinking about adding another battery what is the solution now ?
Powerwall2
I need a 3 phase compatible battery for our house so unfortunately no use.
Do you have a battery for your solar panels, Sam? (yet)
Do you really believe Sam has 50 or so panels on his roof? 50!!!!
I don't. Perhaps he should post a photo. But he won't because he can't.
By 2030 solar could be gaining 5% relative power market share every year leading to a 100% solar powered world by 2050.
A 100 percent solar powered world
Will NEVER happen.

I can tell you weren't impressed. Game Changer wasn't mentioned once. So, I'll skip the Powerwall 3. 😂
But if you have a powerwall 2 you cannot add a powerwall 3 to your existing system - disappointed'
Stuff Tesla as a green solution .. i would love a Tesla battery system but these guys charge way tooo much .. to pay Musk's 40 billion dollar bonuses ..
bring on a BYD competitor etc for $5 or 6k and then we have a truly green solution that makes solar pay itself of ..
The tesla powerwalls are hideous expensive.
A bev is more affordable.
New EVs have car to load or car to grid. That will kill batttery systems, especially Tesla';s horrendously overpriced stuff.
If you have an EV which has V2H where will you get power to Charge your EV.
For a domestic home set up I do not believe an EV with V2H will benefit the householder except in a power outage
