Hi Jim,
You have not allowed for inverter losses which are at least 12% nor voltage drop losses on the DC side. You have not allowed for power factor losses, either. 140 watts of television will draw about 14 amps from the battery bank. If you want, go check it with a fluke clamp on meter.
It is almost always a mistake to "low ball" battery drains.TucsonJim wrote:pianotuna wrote:

14 amps is a little high. Current can be derived as follows: Wattage/Voltage = Current. So 140 Watts/12 Volts = 11 2/3 Amps.
Good points. Didn't realize you were talking about using an AC TV through an inverter.
