I want to power the ThermAssure from a car or boat battery. Do I need an inverter, and if so what kind?
A. As with using a power generator, the most important thing to understand is what the AC unit will draw from the inverter while the compressor starts up. The starting power is roughly three (3) times the amount of power needed to run the unit. We recommend at least a 1000 Watt inverter for initial power-up. Once powered up, about 380 Watts are required to maintain air conditioning. The heater requires about 600 Watts.
