I'm running two of these units stacked. When my rooftop a/c starts up it trips the GFCI outlet in my galley. I put a volt meter on that outlet and it shows a drop to 96 volts when the a/c starts. My a/c requires 25 amps to start and I'm at 3100+ feet of elevation. I also turned off my battery charger and it did the same thing. Once it is running (14 amps while running) everything seems to be fine. Any advice on what I can do to avoid this? CPE suggested a hard start capacitor but I'm interested to see if there are any other options out there.
