OP here. I have three Solar Cynergy 120W panels(plan to added two more). Each panel is wired with 10awg going to the circuit breaker panel. The white breakers are for the panels on the left side of the MH. The red breaker will be used for the right side panel, when installed. From the CB they go to the combiner box post. Then from the Combiner post to the Morningstar TS45 and the batteries(4 GC-2) the wires are #2AWG.I have a 60A fused at batteries on the charge line. The batteries are all wired up with #0AWG and feeds the MH disconnection switch.
Right now, I average 25-35 Ah per day, but I have trees hanging over the panels, but I can keep the bank charged. Best I have seen for now was 19Amp and that was leaving from camping last week. Was parked in the sun early, waiting to get to the dump station in the morning. My solar is more for when we go out towards the west for our winter stay. Gary
