how long would an 5000 btu house air conditioner run?
or maybe a 12v? ima truck driver my truck has a 12v system for ac but 4 batteries is not enough for the heat.
thanks if you can help me.
5000btu uses about 500W full on, meaning if it runs at maximum like when it is very hot outside. Then a 2500Wh battery when fully charged will run it for 5 hours. If it's more mild, you might only use half the energy and it will last 10 hours.
@@BeatTheBush thank you 10hrs is actually the desired time. since we have to stop 10hrs to rest before we can drive again.
thanks for the info. will tell my boss about this batteries.
I have about 16 batteries that are all 200 AH deep cycles that idk what to do with lol.. tossing that out there yall
This batteries work with a schnider inverter?
I just ordered Eco-Worthy 560Ah/7168Wh (2x 280Ah) 12.8V LiFePO4 for $950 from Amazon. $0.14 pennies per Wh. Best deal I've found yet.
2x 280amper 12.8volt in parallelo is 560amper in 25.6v is 280amper 7kw ok
@stefanocerna6504 You're correct, I fixed it. (2x 280Ah). Thank you!
I also Opted for 2 CHINS 280AH Batteries ran in Series for 24 Volt Systems for a Total of 8 and 8 Renogy 200AH AGM Batteries in 24 Volt Packs to Buss Bars to Power 4 Separate 3,000 Watt Inverters = WIN / WIN
Make them both for around $200 each the BMS should be the most expensive part!
They're all cheap Chinese 💩
You’re seriously one of the most useful TH-cam channels I’ve ever subscribed too. I’ve followed you since I graduated high school in 2016. Thanks for all the information and entertainment!
Wow, thank you!
Will Prowse has some good info from years ago before he got filthy rich. Now it`s a rich guy channel.
Very articulate and he does go into detail more than any of the other TH-camrs on solar I’ve built systems and this guy knows what he’s talking about and he actually describes the smaller details that you need to know I really like this guy
Thank you for including the cost of tools in your calculations, a lot of DIYers don't.
This is the most explanatory solar/battery introductory video i’ve seen so far, regarding having all the necessary information to understand how the system is working, important info about usage of the system, and best practices.
Things like the lifepo4 charge-curve are important to know when monitoring a system by reading voltages manually during charging and use to better know the true state of charge, and the characteristics of the battery under load.
This is a good resource. Great video.
Breaking down even the terminal post size was pretty impressive. Most people just want to impress you lots of numbers they don’t understand but this was well thought out.
As someone that has built a DIY to power most of my home office, I absolutely appreciate the level of the detail you get into that other videos don't. The bonus is that I even picked up two bits of new/good information. I LOVE the voltage chart at the 6:00 minute mark. Very good visual. Also, I hadn't thought about getting an inverter that can use both AC and DC and having it switch over to the grid if the batteries fall to a certain %. Very, very nice work coming from a fellow solar content creator! :)
I do the same, im completely off grid but often look at these vids for any new pieces of info, maybe something i overlooked.
@@maddhatter3564 It's because solar is not good.
You are lacking something and it is energy security.
Which is why you are constantly trying to learn more tricks to squeeze out more power from something not capable of delivering.
@@commoncentsamerican solar has actually done me very well but theres always room for improvement. You know nothing about what you are talking about.
@@maddhatter3564 Okie Dokie Solar Wacko whatever you say. You will never convince me this trash tech is worth anything. You people spend more money in batteries and gear then you will EVER save.
Ive got an offgrid office aswell I DIY it with scooter batteries, Love these videos to see other DIY options
Gold. Thank you for sharing your knowledge and also shining light on the truth of needing to become an expert on any diy venture. The end result will almost always wind up saving you money. Very smart, thank you.
I've seen alot of channels on this type of information, this guy really knows his stuff.
Awesome … as an engineer myself, this is discussed at a simple enough level I can completely understand. And maybe even attempt to keep the fridge and freezers running after a hurricane
You do a great job explaining all you need, I did the same thing for my office and was continually buying, this piece then that piece off of Amazon until I got everything I needed, I wish I came across your video first.
I love DIY because it takes a certain type of person to do what you're doing. I love the channel and the video. Thank you 🙂
Awesome explanation. SO many people don't put the time into the whole package. I for one need this detail.Thanks for putting this together.
What’s so weird is I understand everything you’re saying, usually it goes over my head but I think I get it, thanks!
This is the best video I have seen on how to set up a smaller solar/inverter/battery system. You explained everything very well and built a nice, practical system that just about anyone could build. Great job!
yes i wish id seen a vid like this before i started in 2012. It wouldve saved me a few hundered dollars in research fails. lol
Excellent guide from zero knowledge to actual installation. Simple, slow but not too slow, detailed and sufficiently thorough without going into too much detail that would make it tiresome or cause attention to falter.
Ive been offgrid since 2012 but still watch these to pick up a point or 2 that i may have missed. from my experience this is one of the most accurate and easy to understand videos . And he avoids the high buck "cool" gadgets that dont do anything for performance.
Even more reason to keep up to date@@maddhatter3564 as it's by no means a mature technology in any aspect of it and replacing expensive infrastructure components is just around the corner. Once off grid one needs to keep a watchful eye on latest developments.
I made (yes made) my own panels about 12 years ago from B grade cells. I constructed 2 panels and had them charge a 12v truck battery, from which I ran the washing machine, 12v lights in the house and more. Mind you, I was only very young and renting a cheap house (lol).
Anyway, what I've learned is I think it's most efficient to push any power from solar panels into a hot water heater or something like that.
First, props to you making your own panels. That takes dedication.
Second, I’m not sure where you’re coming from on the water heater thing. Resistive heating is not the most efficient way to heat. Heat pumps are usually far more efficient.
Also, I don’t know for sure, but thermal solar panels may get you more heat than using photovoltaic panels, based simply on the fact that any time you convert energy, there are losses, so a straight heading panel would be less conversion than light>electricity>heat.
It's actually cheeper to set this exact system in Africa than in the US 😮
Welcome to America….
By how much?
Ive heard that solar in mexico is cheaper too
Maybe because that's where the lithium mines are
If only africa had amazon and purchasing is more risky if dodgy cells
Thanks for this video. Built system with your replacement Eco-worthy 3000w charger/inverter and two Eco-worthy 12.8v 280AH LiFePO4 batteries. Very straightforward build and list of part was of immense help. All working really well as backup with plans to move a circuit or two from main panel to this (two 200w 18v solar panels in series).
It would be helpful to someone wanting to do this to show your inverter parameters. Hard to find what to program in and Eco-worthy is difficult to get info out of. I just used the LifePO4 battery type with 8 strings for my 12.8v batteries.
This is a very good video. You have explained a lot things other similar videos do not. I went the solar station route because I do not understand electricity enough to be comfortable with it on my own. I bought 2 pecron stations each for $855 a piece total of $1710. That gives me 2 2000watt inverters and 2 1980 lifepo4 battery's for 3960 total battery storage. I want to build a system like yours as well because I just got to. Thank you for your explanation of best practices on charging and discharging these battery's because most YT channels make it like just charge to 100% and discharge to zero which never seemed wise to me. Everything in the video was educational well done!
exactly, 100% charge and 100% discharge can be done but it hurts even lithium batteries. As does fast charge/fast sischarge. Which is what EV owners soon learn
Lifepo4 is good da 20% a 90% long time 6000cicle
First time watcher, I’m half way thru but it’s great to meet a fellow EE’er. It’s funny, we all talk alike. When you get to Ph.d. EE, the lingo changes but we still talk very much alike 😅. Great video, cheers!
I REALLY like these kinds of videos. I am an electronics hobbyist/geek and DIYer so its always a pleasure to watch your videos on electronics.
Glad you like them!
I couldn’t find best video ever on this topic. Congrats! Best wishes & Success!
I'm in the research process to do this, very helpful. I just converted my 24 ft motor home to 200 amp Renogy lithium Iron phosphate, Renogy dc to dc with solar input. 100 amp solar on the roof.
are you sure its 100 amp? perhaps 100 watt? 100 amps of solar would be huge even at 24vdc (thats 3000 watts for a 24vdc system, 1500 watts for a 12vdc system.)
excellent work, brother! I too have recently been introducing myself to DIY solar. I want to spend as little as possible to power the essentials of this home (2 refers, and 1 WFH desk office) in case of grid failure. Thank you for your skills at explaining the details to us rookies out here. Greg (garden grove, CA)
Well done, thank you - I needed the cliff notes for perspective before getting too deep into it and your video really helped
This is great! Probably the best youtube video on looking at cost of a DIY solution.
Very clear and excellent presentation/demonstration. It would be nice to see a bit more details on how you hooked everything up.
Well done! Brilliant description of all factors of the batteries and charge system. You are a clever chap - thanks very much - John
thats amazing. Did a similar thing a decade ago DIY, but building a new house now = LEZZGO.
Great video. Excellent explanation, and description of everything involved. I also like your strategy of using the system in a modular sense which is something I never considered. Leave the grid power for the large appliances and use the solar for specific lower loads. Brilliant!
Dipende con inverter ibrido a48volt tipo easun 6.2kw con 400euro is good for house e puoi lasciare la rete per caricare dall inverter quando non c'è sole
I am building this exact unit for my ADU, however, I am going with a PowMr 3000w 24v for warranty reasons. For the last year, the ADU has been averaging about 2.8kw per day. I should be able to offset a large amount of grid energy with this setup. Thank you for taking the time to produce this content, very informative.
Beware of the PowMr as requires a minimum 120V PV operation for MPPT. Meaning you'll need at least around 7 panels in series depending on the panel you use. If you have that many, no problem.
I have run a large house on 6kw solar 10kw battery and powmr 5.5 kw inverter for a year with no issues on 240v in Australia
Thanks for the video…I didn’t expect to find 12v batteries that are slightly near lifepowers abilities at a lower cost than lifepower so easily.., I have looked at lots of options but these look the best choice as of now for me.
1 Gets right to the point
2 Spoke quickly like a newscaster. Otherwise, I swipe to the next video
3 this took a lot of preparation to put this together
4 it was nice he used inches for my sorry butt that hasn't learned the metric system that everyone knows but me
5 several charts that his explanation were easy to follow
6 I own a company that does remodeling carpentry, electrical, plumbing every day, and I never realized how involved the new batteries are vs the old school marine batteries that we have used till now.
Thank you brother just a great job
Everyone I know uses standard units of measurements
stop the flow, slow the speed
Excellent Video. Direct and to the Point. Great editing. Thank you
Excellent idea and information. I have subscribed to your channel because your knowledge and delivery are excellent. Thank you. Keep up the good work!!! ⭐️⭐️⭐️⭐️⭐️
Thanks for doing the video, great help for me about to set up a 10kw system to use night rate power during daytime.
Video very well done. Squeezed a lot of DETAILS into a short period. Many others omit important details. Thank you.
Excellent video, you were very clear and easy to understand. Great job.
Thanks great stuff! This is the best way to feed my house his sleep consumption including my office.
pretty clean and tidy setup.
good job.
Whaoo! What a scoop, plugging 2 batteries together, connecting them to your system with stuff you bought that can be made out of squashed copper tubing with a hole drilled into it... Anyhow thank you for your efforts, good luck with your set up.
Thanks, good one, volts,amps watts,dod, cables sizes etc. Well explained.
Build an off grid system myself with 5kwh of storage. We are a lower energy user but looking at 3.4 year pay back plus it will run in the event of grid failure. So far going great really pleased.
3.4 years? Wow, I can only get that low with a battery less grid tie system.
@@BeatTheBush I sourced and installed. 6 jinko tiger neo panels at 435w each. Mpp solar invertor and renogy batteries.. panels have sinced dropped in price....
Thank you so much. I love and appreciate the information on this. This will definitely help when building a tiny house.
DIY Solar ☀️is exciting and the components are getting better while prices keep coming down. I recently built my first 3000 watt system with a 5.12kWh ⚡️battery and solar panels for less than $3000! You are so right in saying people need to start learning new skills to leverage their knowledge into ways to save more money 💵. Our goal now is to take our entire farm off the grid completely! Lots more to learn, but we’ll get there!
My state screwed us serfs over. They were giving away 200 foot fire watch towers free, just pick up. But only to other government agencies.
They would be perfect for a combination water tower, windmill, solar panel rack, TV Radio HAM radio antennas, wifi AP, weather monitor, and intrusion observation point.
and of course a zip line play area 🤕
@@robertsmith2956 offer a local agency you trust the members of to use your land for little to no charge as long as you have access to the tower as well. You'd probably have to work with an attorney for liability/'limited use' clauses, as well as right-of-way access to the tower on your property, but it might be worth it!
@@jmax8619 To much invested in trespassing all government from my land to open an exploitation point.
Your emojis made me think this was an AI comment, but clearly it's not.
I guess this is the kind of comment they trained GPT on though 🤔
Great Video. I’m going to have to watch it again just to get more of the details written out.
Awesome video! I've been wanting to build a battery backup system and this covers all questions I have on getting started. Thank you for the upload 👍
Glad I could help!
Thanks for the insights on how to build one. Although we have solar at home, this is extremely interesting if we wanted to DIY a separate one
A great learning experience. BUT if your energy needs are met with solar, then it truly becomes a hobby project.
set up a separate small system for climate control of the batteries. Never hurts for them to have a space heater, and window ac to keep them happy.
If nothing else use the power to drive the solar tracking system, and get those last pesky electrons hiding in the shadows. 😎
I wired my house into 6 zones so I could bring each area online one at a time.
ROI is less than 2 years that way. and you roll the savings back into the system. A side benefit, is EOL is staggered as well, so no big hammer at the end, just continue the pay it forward.
solar bank one gets to old, replace it, not entire systems panels all at once. Same with batteries and inverters. and if a failure happens, you can decide what area gets the outage, and keep the critical system active just moving a power cable.
I have my emergency lighting, and alarms on a separate system with no inverter at all, straight DC. I put the LED cabinet lighting in the kitchen on it, so it does get used between disasters.
It is tucked away in my storm shelter.
Wow, the Best ever, this system is perfect and very well demonstrated
So glad this video appeared on my feed! I've built the my own using the kepworth 200ah x2 and watching your video it looks like I've done a good job as myself I've got no experience previously. It's been running 10 months Running 80% of my house daily Just got to purchase bigger Solar panels, and the extra information on the battery charging was most helpful as I charge at 20a which now i know it the correct amount But I always fully charge the batteries in General they use 30% daily then fully charge to 100% Now I'm going to change it
If you want to get extra life out of them and you only use 30% and not mind having less reserve capacity, charge to only 80%. The top 20% and lower 20% degrades the battery most.
Thanks for the facts and not sales dribble. Its a great video full of actual information
Love this! I was thinking about this the other day. Thanks for the content.
Glad it was helpful!
THANK YOU1111 Yours is the absolute best video on the topic and I've been researching all week..
Thank you for the educational class, I learned a lot in a layman terms.
You did an amazing job explaining this! Thank you!
Appreciate the video fam !! 🎉
Very well done video sir! Well explained with correct technical details! Subscribed! Glad to have found your channel! And thanks. I didn't know these batteries were out there, I might have to build something cool with these. Like maybe a raspberry pi 5. Server stack or something, always wanted to make a solar powered server stack.
Excellent video. The 200ah batteries are a good choice for more than a one battery installation, but if you need it, 2x100ah or 4x100ah batteries allow a higher discharge rate with their 2 or 4 BMSs. Looking at the company's pricing, they may even be a bit cheaper.
Thanks, great stuff. Really good explanations. Thanks again!! All the stuff I wanted to know.
Thanks for your sincerely given advices. Take care of yourself.
Preach it brother, get down with the lifepo4 sickness!! DIY is the route to go because nothing is better than knowing precisely how everything works before you jump in the bandwagon. I have been my own DAILY power man for at least ten years, my work is more reliable than our power grid. My lights are still ON when the power man, PG&E cometh to investigate. My battery bank always blows their mind. I can go for an entire week in crappy weather without firing up a generator.
Excellent! Subscribed and keep up the good work. I wish more people would look at these systems vs Li-ion battery walls that can be far more hazardous and far more expensive. These batteries will last longer also with more usage and cycles.
I was subscribed to your channel very early on when you started, but TH-cam banned my account and lost all my subscriptions, now that I found you I remember you used to make very useful videos such as this one, I'm glad I found you again and subscribed.
Welcome back!
Super video, thanks for making! 🙏
Nicely done, sir!
Excellent video. They also have rate plans that have peak metering where I live, if you can store energy and not use any during high-demand hours rates are very low so they can balance loads. There are alternate sources of energy storage that can be had at very low per-unit prices, but these are getting very cheap. Subscribed
Clear and concise.
Very well in detail explained. Thank you very much!
Great video, well explained.
Good job
Thank you so very much for sharing this!
Excellent! Very detailed and informative. Wondering if one could run a furnace in case there’s a power outage. Not sure about the typical amps and wattage needed but it would be a good exercise. Thanks again
Ok my unsolicited opinion the quality of the video production was above par as was the scripting, editing and videography. The content in clarity, explanation and continuity (no pun intended) was very well thought out and offered. I just can not come to the place where I need to do this because I use on average 600 KwH of electricity a month here in Thailand. My electric bills are consistently 60 dollars US. So 10 months for 1 battery makes for a difficult decision but these videos make for an interesting case. I have an unfair advantage over most as I was an electrician for the railroad and understand the wiring,, termination and cabling more than most folks would..... Thanks for the vids and this one earned a sub.
20kWh a day... not unreasonable but your rates are so low, it only makes sense to do this for energy independence in case the power goes out. As a hobby, I watch the solar come in daily and it's my kind of fun!
I know a man that when he built his house he had one breaker for each outlet, he had like 3 or 4 panels, he said it saved money on electricity, curious if you were talking about anything like that
I like this type of videos.
=D
Me too.seems like the kit would be more economical for me. But my electric bill currently is $26.10 for the next six months. So if I keep this up my ROI won’t happen until after I die.
I'm new to this, just five days into my research. I hope our governments are pleased that we're doing our part to reduce our carbon footprint. ✌️ I recently acquired a Vtoman 600x to experiment with.
First class work. Thank You
Very informative. thank you.
I like this video as well , the birth of Lifepo4 battery.
I will later grab me a few of these but right now, I'm enjoying my Ecoflow Delta 2 .
Very good video right on point on your information
Excellent explanation. Great Video. Thanks.
I have a very similar system. It feeds my bedroom off grid. Its great because even if the power goes out i can still function in my beadroom. I have 1.2kw solar and 3.5kw inverter. Also running 24v. I don't know if it actually saves me much power, but its nice to not worry about any power outages. Yes the cost of all the breakers and wires add up. I mounted mine on a board on the wall the same way. Its right near the breaker box. I disconnected the wire from the braker running to my room and connected it to this system instead. That way i didn't need to run extension chords, just use existing outlets.
1.2kW solar, you like are making around 5kWh/day. If you use all of that and the battery never tops out, at $0.33/kWh, that's $1.65/day so from that you can check your break even point.
Seriously, great video. Thank you so much.
Excellent video and very informative.
I have a farm and did the math to run electric from my house to the barn, solar was much cheaper and more fun to do, only have 100 watt solar to run my lights i want to add 300 more, your video step by step was what i need to finish thanks
That is awesome!
Ive been waiting for your to do this since I am building cargo van solar build!
Yep. This will work for a van build indeed. 3kW can power even an electric stove. This inverter uses about 30W when on, and 15W on eco mode.
Thank you for the detailed explanation definitely Awsome.
Well explained video 👍🏻
I built my system to just protect the small Freezer & large refrigerator , patio fish pond & lighting using 5ea 100 watt panels ,3ea 200 amp battery. plus loads of hook up. P.S. my panels track the sum.very efferent & not a lot of money , jots of time, the learning curve.
You have videos on it?
Listen to this guy sounded like a real electrical engineer, Cmon Francis😂😂
One thing to note, most imverter or UPS systems conceal the technical data as to what features and capabilities they have. Marketing has a way of eliminating the need to use your brain and obtaining a system you can build yourself. They always use proprietary connections and electronics to prevent you from using competing products to justify charging you more money.
Load balancing, zero switching time, voltage leveling (continuous inversion) high current transfer switching, current and voltage monitoring, temperature charge monitoring and calculated runtime are some features they are capable of having. You can even gave fancy systems which omit the transfer switch entirely by providing a supply conversion capable of supplying the entire output current needed for the inverter ratings. These systems are typically more lossy than using a transfer relay but are desireable for electronics.
Most people are lazy and ignorant and more than willing to pay for it.
This what I want as a backup system in case the grid goes down
You explain so well, are you a teacher
Can you please show us your solar panel setup? Thanks.
Great video - very informative 👍👍👍
Thought the batteries were huge for the capacity but it seems you are a compact human lol. Will sub.
Thank you for this video
Thanks, great explanation.
Excellent video!
Good content. Easy to understand.
