I am considering buying 4 Battle Born 12 volt 100 AH batteries and wiring them in 2 banks of 24 volts each, and connecting them to a Growatt SPF 3000TL LVM - 3kw 120Vac all in one inverter/charger.
I would like to wire the batteries in the most efficient way possible, and I want a disconnect between the batteries and the inverter/charger, along with overcurrent protection from the batteries.
Is there some sort of combiner box that would give me overcurrent protection as well as a disconnect between the inverter/charger and the battery bank?
I have been reading about Square D QO breakers being DC rated, but I don't know if this is the best way to get what I want. I guess I would need two breakers for 100 amps each at 24 volts.
I think the benefit of a DC breaker box is that I could have one large cable off the positive buss bar and one off the negative buss bar going straight to the inverter/charger. I like the idea of having the electrical connections inside of a metal breaker box.
Any thoughts?
