TV Running On A 1200 Watt Inverter

TV Running On A 1200 Watt Inverter

There is no trickery here and the Xantrex battery monitor is not lying. Running this same exact TV on 120 volts AC through a 1200 watt inverter uses 5.8 amps or 5.8 ampere hours for every hour of run time.

When compared to running this SAME EXACT TV on 12 volts DC the inverter is 32.8% less efficient or a far cry from what many would assume is a 10% inverter inefficiency.

Keep in mind that a good portion of this efficiency loss comes from the conversions from DC, to AC and back to DC through the TV's "wall wart" and the other portion from the inverter..
