Off Grid Solar Powered Battery Backup System - 24v 

Looks good. If you need to heat your home during an extended outage you should consider a diesel or propane heater. This system will be good for baseline loads (lights, fridge, etc..). I also watch Offgrid Basement’s channel and his 24V system.

Ah, the ol' circa 2019 Will Prowse system.

Nice build!!! Safety thing to consider....I'm guessing your relying on the BMS's to protect the Batteries if a short of some kind were to happen at the batteries???? Something getting across the the batteries and arching....I didn't see any covers on the battery posts?????That big fuse for the DC input really needs to be on the Battery end of the feed wire to protect That wire.... You choose wire size to handle the Load and fuse size to protect the wire but the fuse has to be at the Source not the Load. The 18 inches or so of 2/0 wire from the battery to the terminal bar can burn up if a short were to happen with the fuse not at the battery POST (Source). In the Commercial world that fuse has to be at the battery post or within 6 inches. Don't rely on the BMS or if a AGM or Lead batteries were ever used. A inspector would insist on it. Same at the Solar panels.

Excellent video. I have several of those Epever in my main setup now and love them. I had 5 RICH Solar panels before and they always worked great for me. And I still have a few giandel inverters. Did a video on a smaller 12v model. Keep those videos coming! subscribed.

Another PowerQueen fan. We’re up up to six, 12v, 200ah Powerqueens, including the four in the bank we use to charge our Ford F150 lightning. We’ll be upgrading that from 10kw to 20kw in a few weeks.

Go for the thicker wire. Spending a little more on thicker wire is better than burning down your house.

Nice tour of your system.

With prices of batteries dropping 50% this year I’m adding more wh 😊

Great system and video. Thank you for sharing!

😄👍Good Stuff, Great Tips

neat job clean looking

Looks nice! 🎉

At 4000 w surge, the maximum draw from your battery bank will be 167A. Your 24v inverter cannot draw all the power from a 12v battery. It needs a 24v battery. If you have 2-12v batteries in series for 24v. The 167A will be shared almost equally btw the batteries. That is 83.5A from each battery. A 4awg wire is enough to connect 2-12v batteries in series if the max amp draw is 167A. 4awg pure copper can handle up to 85A.

Nice setup, try with our 12V230Ah

Neat set up😊

how many watts from solar panels do you need to charge that battery bank in 6 hours ?

I'm building a system very close to this

How do i wire 4 eco worthy batteries for 24v? ,i have 50mm2 copper cable ,thanks

The red and black + and - junction boxes at the bottom of your board...where did you get those, sir? And thanks for posting your build, sir. Also, do you use battery terminal covers?

Hey, just to let you know The Wire that you got going to. Your inverter needs to be upsize. To the same size that you are going to your batteries. Because those wires oR way under size. I have tried. The manufacturer size and found out that was a cause of the emperor shutting down. And The wire was Getting hot.

Did you mention what kind of battery you using lithium .

Does it matter pv 8awg to 6awg can i just keepnit 8awg

can you keep your battery bank charged using the power grid?

The research that I've done? You should never mix different size batteries and different companies. I'd like to put a UPS in my home so I bought two UPS inverters/chargers(2000w) and hooked up two batteries parallel to a 2000w inverter to back up my sub pump. My 1/2 horse sub pump comes on for 1minute and 20 seconds twice an hour. 1050w start. at 10 amps. then drops to 960w at 8.5 amps. @120 amp hour battery draw it will last 5 to 7 hours approx. Two 100AH batteries in parallel should last 10 to 15 hours or more? I have outdoor solar lights(street lights) Some nights they only last 2 hours? other nights they last 10+ hours. It has to be a sunny day to get a full charge. I'd like to go 100% off grid but I first need it to become economical.

lets clear this problem of weir size's up once and for all . when charging a battery power in put is amps irrespective of or voltage bank copasetic . 12 volte siystom or Or 24 volte Siystom it is So we ues to cabal suitable of carrying amp's like them on an ark welder our battery bank will adapt nicely to this point i use a simple gild line of fore determining the size . given meny of use do not have chats & graphs to tern to. the stander ark welder of 150 amps use's tow size of weir i opt for the larger size on 12 volt battery banks often the smaller size when used as jumper cabled get to hot Go for the heaver size of cable you find then in the good quality jumper cabal packs . often orange , Then we have the heavy Ark welder such a the , oxford welder Oil fold welder that pumps out a staging 200 amps this type of melty core cable is idle for large battery banks. from 24 volt & 48 volt siystom battery banks , that require heaver amp's to charge them. [ Remember amp are the systems by witch we fill our batteries with a check valve. not unlick a water tank with a check valve , think of it filing the tank as it dose so it develops presser from the filing tank. this presser pushing back on the incoming water & slows the fill. this batter slows the fill & more presser is added to fill. if this tacks place whit current [ presser in amps ] will heat's up the cabal & the larger cabal can except this current with out damage to the malty core cabal , But the smaller cabal Heats up to a point. Of Melting & will & often can start a fire . this is the way i use the cabling I'm going to use lower amps when charging do not over heat the cabal. Hirt amps will heat up the cabal. & keep cabals as short as you can hop this helps you ,

If you hire someone to do it. Then you won't be able to work on it when it counts. Solar isn't worth it if you can't do it yourself.

👍👍Wow! It's really cool. See also: Solar power plant mounted in multi-storey building!

Great build until you got to that cheap, low surge capacity, high frequency, transformerless inverter. High frequency inverters are not much more than a toy when it comes to reliability, performance and safety. They offer the poorest surge capacity ratings and a much short life expectancy than a real inverter that uses low frequency, transformer based technology, and because they don't have an iron core, copper wound output transformer to isolate the DC boost stage from its AC output, there is always the possibility that this cheap Chinese made inverter can pass DC current to your AC appliances and set them on fire.
