Two breakers on one wire.
My old system was very simple and only had a breaker on the solar input for convenience and is located inside the power shed. However, I now have 4 panels with two series and then parallel via a combiner box with breakers that is located outside the power shed. I didn't really think anything about it till now. Is it OK to have the solar positive going into the breakers in the combiner box and then the combined output of that going thru another breaker on the "shutoff" box inside the building? Breakers in series?
4-Risen 320 watt in series/parallel, 8-215ah 6 volt GC2 batteries in series, Exeltech 1100 watt/48 volt inverter, Tristar 45 MPPT controller.
