DIY 2000 watt, 24v Solar Power System w/ LiFePO4 Batteries

what is the size bus bar you have used please? it isn't listed in the Recommended Components list and you don't mention the size in your video. I'm a total newbie with solar and would appreciate this information. There are so many choices on Amazon with different amps, volts, options.

They want well over $3000 to get one of those Battle Born batteries to us here in Aust

Can I have it all at the same time 12v. 120v. And 240v ?

Hey Will, I have a 2000W PSW inverter, but it is for a 12v system. Is there any way it can be used in a 24v system? Can I somehow boost it to 24v? Thanks!

Instead of using that 24 to 12 converter couldn't you just hook to the center positive to pull your 12v?

Very good comparison touching all aspects of the system (performances and costs). Thanks

What da heck were u talkin about charge profile parameters

How come you never seem to have any positive wires connected to any fuse boxes in your videos? How does that work?

Can you please explain why you put “don’t use battery protection” on blueprint. Thanks! Love your channel!

Can you get protection from gamma rays

If battery manufacturers solve that problem then i will use lithium

All lithium batteries burst in flames too risky to use as home grid power storage

Can you use the transfer switch to take input from an alternator so this system could go mobile? Assuming I have a dual voltage 12v/24v alternator?

Thank you for tackling something 24V! There is a large community of folks that have ex-military vehicles that have either straight 24v or dual 12V/24V systems so this will be a big help. While I’m not making a camper on my truck, many other owners are so this would be helpful.

I know this video is old, but you're blowing my mind it looks like you're feeding the inverter more so from the charge controller opposed to the battery Bank? (even though it's all the same positive cable but you're tapping and closer to the CC and on top of battery protect). Also the victron battery protect pdf/info says that you're not suppose to use it in-line with the inverter and if it gets damaged while doing so then it's not covered under warranty.
I'm a master electrician and electrical contractor but there is some seriously conflicting info here and now I'm stuck until i solve this.

Do the panels have to be wired in parallel for this system

Great content clear and concise 🙏🏻

This is almost the same as the 24v system I'm building. I noticed you had removed the Victron battery protect for some reason. From your parts list. My inverter has a low voltage cut off of 20v and I read somewhere that this is too low and will kill my SOK 24v battery. I know the battery has a BMS that will shut down the battery before that but I don't think this should be it's primary protection. What else can I use to protect my battery? Anyone?

"Or use them in a stupid fashion".... have we met? How do you know me so well?

I ❤ to hear this type of connect

Amazing how much things have advanced in 4 years. Now we just need an all-in-one inverter and a rack mount battery and save all that extra wiring,

Thank for the knowledge. Why you chose that inverter

Does this system need to be grounded? I am going to put mine on a Dolly.

Would 8 3.2 volt evo’s work with this for the 24 volts?

It does look good. i'd suggest putting the fuse/connector on the side at top for easy access.

can I just ask, why a 25 amp fuse? struggling to see why. Thanks

I like Will's videos but I do not like the way he never responds to any questions about any of the videos. Like on the blueprint link of this one he has do not use the battery protect but offers no explanation , like it is not needed because the batteries have that built in , chargers have protections built in ! Might as well not ask here , he has a chat room and I'm sure there are people there with lots of knowledge. Not trying to be critical if you read this Will , I'm sure you feel you just don't have time.

Note: the new tax law allows for a 30% solar tax credit on your energy storage components IF it has a capacity of 3kwh or more. At 12V, that's 250hwh. So you could add a third battery and potentially recoup the entire cost on your taxes. You can also buy 250ah or 300ah batteries that should qualify.

That should read Amprius batteries

Could you a bit on a Prius batteries

Built my system to look a bit like this, mine uses the MPP lv2424 hybrid instead.

Can I use 4 gauge for the entire build?

My solar array consists of twelve 195w panels connected to a six-string PV Combiner Box, for a 24v system, to a 3500w PowMr solar charger inverter, currently with four 12v 100ah Sealed lead acid batteries ( I would like to upgrade to Lithium batteries with to at least double my storage capacity). Which is better, 12v batteries at 100 ah, hooked in the same manner my SLA batteries are configured, or would 24 v batteries be better? And if 12 v or 24 v batteries are recommended, which ah rating... 100, 200, 250? and which BMS rating...100, 200, 250?
As soon as I think I've got it figured out, I watch another video that doesn't quite answer my question and I get confused all over again.

Hi can I put just one battery 24 V instead 2x 12v in series ?

What’s on the other side of the board ??

Think in Horse Power and you know,what the Job of one Horse ist one Horse,=745 Watt !!!💖🙌😂😂😂💕💕💖

Great video, always enjoy your information. Can you wire 6 12v 100ah lithium batteries to get 300ah for a 24v system? Series parallel of course. I've been told lithium doesn't work well in that configuration. Is that why you only have 2 12v batteries? I bought 6 weize lifepo4 lithium and plan on wiring to bus bar each 24v set for a total of 300ah. I haven't seen any of your videos showing that many wired in series parallel. Any advice is appreciated! Thanks

So what happens to all the equipment you review? I’d be willing to pay shipping on some of your leftovers.
24v200 lifepo4 would be nice.

Does washing machine is working with this ? Thanks

Can you do more 24v diy videos. Not a lot of content on the tube for 24v. Love your channel and your book btw.. Very detailed and informative.

In Victron Documentation they forbid and do not allow using a battery protect to connect an inverter thru that battery protect directly

Love your work

What is better 24 volt batteries or putting 12 volt batteries in series. Was thinking savings in wire would be worth 24 volt batteries. Any help would appreciated.

Дякую за відеоогляд!

I’m looking to buy a couple of inexpensive solar panels. Would like to use them at 24V for exterior landscape lighting! Would like to know if I can use the same setup for emergency use on my house. If so what might you recommend. I totally new to this sorta stuff!

Hi love your videos I wonder if you could give me some advice please
I have a shed with 3 x 125w solar panels and 3 x x100amp
Batteries
I would like to use my inverter to charge up my power tool batteries could you tell me what solar controller would be good and what power inverter cheap as possible

You do a real good job on your videos. My question is I put a battery switch into the 25ft camper I use as a camp because there is soo much hidden draws. Where does the electricity go once the batteries are on float? Is this an ok situation

I'm pretty new to solar so forgive me for asking, shouldn't this be grounded somehow?

Thanks for the video. Would this be a good setup to run a washing machine once a day, 120 volt - 15 amp - 1800 watts? I think there are 3 eletrical basic minimum things most people need to get by with life mostly normal: small fridge freezer, communications / internet and washing machine. Cooking can be done in many non-eletric options so assuming your in city water, I think these are the three primary items most people need. If you could make a setup designed to cover these basics I think that would be awesome!
