Hey everyone,
I was wondering if there is a manufacture who makes utility scaled PV combiner Boxes with a DC disconnect switch that separates both the positive and negative feeders. My thought is that once the hot lead is disconnected then there should not be a positive voltage at the inverter terminals therefore no potential for arc. However, I am doing my due-diligence and wondering if there will also be a benefit to disconnect the negative lead.
