um, 15amps at 110V is a LOT more than 55amps at 12v...

really, for occasional use, light duty a cheap 750 inverter will handle lights, radio, and refrigerators no problem. and you don't have to go get gas for it. your car will handle it fine. that battery is amazing.
if you NEEEED a generator, get at least a 5KW... don't bother with those glorified inverters, just get a real inverter and use your car.
