I was told by my converter (Liberty Coach) to not run below 110v to stay on the safe side. The coach is in a large storage garage and I can check everything from my iphone. This morning I was showing 111v on leg #1 with one air running. I also have two refrigerators (small one in basement) and the battery charger will charge as needed.
Apparently when I checked, the battery charger was on and then turned off and the volts changed to 114v. So, I turned off the front air and turned on the bedroom air as it's on leg #2. It was showing 116v on leg two with the air running and leg one went to 119v.
