  • I don’t know what might be best, but I’m curious myself. So I hope someone can help.

    I have been doing some reading, and it seems like you’d be giving up a bit of functionality with not having a smart BMS with that victron piece.

    For a future-proof, safer, and smarter setup, upgrading to a CANBus- or RS485-enabled BMS that speaks Modbus or Victron CAN protocol is highly recommended. It makes system integration smoother and battery life longer.

    I don’t know which one would be best though. Maybe something like this? https://overkillsolar.com/












  • I have built this, it’s not perfect and I made mine a little over kill. I even have an extra inverter because I tried to scale mine up to charge a Nissan leaf. It successfully did so, but only for a few minutes before it would get too hot

    What questions did you have?

    As for advice, buy the correct crimping tools, a good set of wire cutters and be sure to get the correct sized wire. I’d also suggest pairing it with a battery, I just did a 12v marine battery lifepo chemistry and made sure my charge controller can handle it. This was actually kinda necessary because it keeps an even charge.

    I didn’t use any calculators or spreadsheet, except the one that showed what the nominal voltages were for my battery

    Also I’d say I regret doing one large instead of multiple smaller batteries just because of cost.

    I’d be happy to help more but just know I am not an expert, or even that skilled at electric work.
