Hello looking for some help before I order some parts.
Main question -- is it ok to use a 200A BMS on a 380Ah battery bank (1C) if we fuse it on the (+) side at 200A?
I'm looking to do a DIY build for a Van/RV with ~ 600W of solar. I'm running an induction cooktop and a desktop/monitor so I wanted a large battery bank.
I'm looking to stay with 12V because it's more standard for cargo van upfits, and I don't want to have to go through all of the 12V appliances and check if they can work at 24V.
I also want to charge from the alternator so I'm looking at the Renogy B2B & MPPT 50A charger, a 2000W inverter, these 190Ah LiFePo batteries, and this 200A BMS. My schematic is below. I also read that we don't need to connect the MPPT charger to the BMS, although I have not verified the overvoltage settings on the Renogy one.
My main question is can I damage the 200A BMS if I happen to draw more current? I've provided the 200A fuse on the main (+) going from the batteries to the loads. The inverter is 2000W and I'm expecting around 30A of 12Vdc loads, putting my total load around 240A peak (including inverer efficiency at 85%).
