have a Camper Box Truck with a 14' box. I also have a 10,000 BTU portable A/C that uses 1200 watts / 10.8 amps). I would like to run the A/C for several hours without a Honda type gas generator.
I was thinking: I could upgrade the Truck Alternator to one that produces 100 amps at idle.
Get a good quality Deep Cell Battery that holds 200 amps.
Get a 3000 watt inverter.
Plug in the Portable A/C.
Start the Truck and just let it idle for hours when the A/C is on (the engine does not over-heat).
1, truck motor at idle will burn lots of fuel and lots of polution 2, 100 A alternator is rated amps at XXX RPM, not at idle 3, a single battery can only supply about 50% of its rate before it is considered dead. 4, 10.8A at 120VAC means the inverter will draw approx 110Amps at 12VDC to run the load. Any more questions?
