I need help configuring my solar array and wiring. I am building a home that is entirely off grid and have purchased 32 - 375 watt REC solar panels. I am matching these with two 12k watt Growatt MPPT inverters and a battery bank of 6 - 48 volt LifePo4 batteries that can store 5k watts each. The array is a ground array about 125 feet from the house.
I was going to wire the panels in 4s4p for each inverter, but that would create strings of nearly 40 amps each and I think would require 6awg gauge wire to carry the load. I was trying to purchase combiner boxes, but could not find boxes that had fuses over 30 amps. Do I need to make 8 strings from each inverter and buy two combiner boxes?
