I will be using 2 renogy 160W flexible panels, 40A solar charger, and 3000W inverter/charge. I have 4 6V 235 amp batteries that the dealer installed and all 2GA wiring. I am pretty sure I need to change all of the 2GA to 4/0 from the inverter/charger to the batteries with a 400A fuse and 8GA from the solar charger to the bateries with a 40A circuit breaker. Does this sound about right for fuse and wire size?
