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?
Thank you for including the cost of tools in your calculations, a lot of DIYers don't.
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.
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.
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
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
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.
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.
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
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.
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!
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
Well done, thank you - I needed the cliff notes for perspective before getting too deep into it and your video really helped
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.
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!
Excellent idea and information. I have subscribed to your channel because your knowledge and delivery are excellent. Thank you. Keep up the good work!!! ⭐️⭐️⭐️⭐️⭐️
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.
I couldn’t find best video ever on this topic. Congrats! Best wishes & Success!
Well done! Brilliant description of all factors of the batteries and charge system. You are a clever chap - thanks very much - John
Very clear and excellent presentation/demonstration. It would be nice to see a bit more details on how you hooked everything up.
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!
What’s so weird is I understand everything you’re saying, usually it goes over my head but I think I get it, thanks!
Excellent Video. Direct and to the Point. Great editing. Thank you
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.
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
This is great! Probably the best youtube video on looking at cost of a DIY solution.
Thank you so much. I love and appreciate the information on this. This will definitely help when building a tiny house.
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
Great Video, thanks for the in depth overview of every piece of the puzzle
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)
Excellent video, you were very clear and easy to understand. Great job.
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.
Video very well done. Squeezed a lot of DETAILS into a short period. Many others omit important details. Thank you.
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.
Thanks for doing the video, great help for me about to set up a 10kw system to use night rate power during daytime.
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.
Thanks, good one, volts,amps watts,dod, cables sizes etc. Well explained.
pretty clean and tidy setup.
good job.
thats amazing. Did a similar thing a decade ago DIY, but building a new house now = LEZZGO.
Wow, the Best ever, this system is perfect and very well demonstrated
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
You did an amazing job explaining this! Thank you!
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
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.)
Love this! I was thinking about this the other day. Thanks for the content.
Glad it was helpful!
Great Video. I’m going to have to watch it again just to get more of the details written out.
Thanks great stuff! This is the best way to feed my house his sleep consumption including my office.
Thank you for the educational class, I learned a lot in a layman terms.
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.
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.
THANK YOU1111 Yours is the absolute best video on the topic and I've been researching all week..
Great video, well explained.
Good job
Thanks for your sincerely given advices. Take care of yourself.
Really like the way you explain things..Good job..
Thanks a lot 😊
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.
Very well in detail explained. Thank you very much!
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.
Thanks, great stuff. Really good explanations. Thanks again!! All the stuff I wanted to know.
Thanks for the facts and not sales dribble. Its a great video full of actual information
Your a bad ass bro, thanks, Iv'e been looking for a good video on DIY BBS, Thanks again! (I subscribed too)
I’ve upgraded this from a 24V system to a 48v 20kWh system, soon it may power the entire house.
Listen to this guy sounded like a real electrical engineer, Cmon Francis😂😂
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
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 🤔
Nicely done, sir!
Super video, thanks for making! 🙏
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
Appreciate the video fam !! 🎉
Awesome video! Thanks so much!
Can you please show us your solar panel setup? Thanks.
Very informative. thank you.
Well explained video 👍🏻
First class work. Thank You
Thank you so very much for sharing this!
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.
Seriously, great video. Thank you so much.
Very good video right on point on your information
Excellent explanation. Great Video. Thanks.
Excellent video and very informative.
You explain so well, are you a teacher
Excellent video!
Thank you for the detailed explanation definitely Awsome.
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.
I will later grab me a few of these but right now, I'm enjoying my Ecoflow Delta 2 .
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 video as well , the birth of Lifepo4 battery.
Good content. Easy to understand.
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 explanation.
Great video - very informative 👍👍👍
Very informative . Thank you .
Great video! My only question is how did you wire the receptacle into the charge controller?
This what I want as a backup system in case the grid goes down
WOW people really don't understand "Radom Acts of Kindness or intentional Acts of Kindness" they actually benefit the giver more than the receiver‼️☯️☯️. I love this guy because he "Gets It's" ‼️✌🏼🤟🏼🖖🏼my friend😉👌🏽💕
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!
Thought the batteries were huge for the capacity but it seems you are a compact human lol. Will sub.
thank you
Thank you for this video
I been wanted to do that for a while thanks
