The simple answer is NO. Each AC unit will pull from 12 to 15 amps HI cool. That leaves you with 3 to 6 amps left for everything else in the RV. Your refer on 120 pulls about 2.5 amps to 4.0 amps. The Power Converter/Inverter-Charger 1 to 3 amps. Add other 120 appliances and you will overload the system. Also, monitor the actual 120 line voltage with a digital Voltmeter. Odds are the line voltage will also be lower than safe/normal operation. If below 110 volts, then shut off 1 AC unit and run it on Hi fan only. There are NO safeguards for running systems on substandard supply poles. If the voltage is LOW, then you risk harm to some appliances including the roof AC units. Doug
