Yesterday, I got to spend my first afternoon with the air conditioner and refrigerator running sustainably completely off of the solar grid, despite the defective PowMr charge controller after rewiring the solar panels downhill and relocating the rooftop ones. Also, I cleaned all the panels too. Instead of 3 parallel sets of five panels in series, I did the opposite. Now, it's 60 volts at 25 amps. It appears the more current and/or the smaller the difference between the input and output voltage is getting the PowMr solar charge controller to put out more when stuck in "absorption" mode 7. I'm getting an average of 650 watts in direct sunlight now, which although is only about half of what I'm should be getting, is enough when combined with the rooftop panels to run the air conditioner until about 3:30pm in the afternoon and the refrigerator until about 6:30pm, leaving me with full batteries for overnight and restarting the refrigerator at 7:00am.
The inverter does not back-feed into the GFCI in the bathroom. The original hot-water heater is wired directly to the circuit breaker. The bedroom outlets are actually connected to the circuit with two refrigerator outlets.
I forgot about the microwave oven! It's stored under the guest chair in the corner for now. The original outlet is near the ceiling above the guest chair connected to the LR/AC2 circuit breaker. It will probably end up in the kitchen connected to the Kit/Ref breaker to more evenly distribute the loading.
