Only draw on shore power is rooftop AC, 1 32" LCD TV, and the refrigerator. Laptop PS, and printer. If I turn off the AC, the voltage will come up to 123 volts with everything else still on.
The sun has set. The AC is putting out cold air. The portable AC compressor has not kicked off. The temp is coming down. The RV voltage is up to 109.8 volts from 107.2 volts. I know that soon it will get chilly in here and I will shut off the portable unit. The voltage seems to be temperature related.
Homeowner has told me to do laundry before noon due to power company charging more for peak hours or something. I wonder if APS is altering voltages during peak hours.
