Amazing how many do not read an OPs post. Every word. I never said a word about trying to run the AC through the inverter. Shore power goes straight to the inverter charger unit & bypasses it. It happens to have a circuit breaker on it which trips. The draw readings on each leg come from a Progressive Industries external box on the shore power post. Used the AC a bit today but jumping up to turn the compressor off manually when the noise built up & before the circuit breaker kicked out gets old real quick. Fortunately here in the midwest days have not been hot & nights are cool. My challenge will be to find a place that can do a same day install of a new unit. We are a month into a 4 month trip.
