How many hrs will two (2) batteries run a 20" flat screen?
Depends on the battery size. If you have 2 each 8D batteries, at 120 pounds each, you can watch TV all night long with 220 AH per battery. A group 24 battery is about 65 AH per battery, while group 27 is more like 100, along with group 30 and 31. Going with golf cart batteries, then the pair of 6 volts add up to 220 amp hours, and should last about 6 hours of running the inverter.
I highly recommend a solar charging system. It will keep the batteries topped up while in storage, and can top off the batteries while camping, depending on the system size.
100 - 150 watt panels will fit on most roofs.

Look for 12 volt "Nominal" panels *the open circuit will be around 21.2 volts*. Also buy a PWM solar controller rated for slightly more amps than the total of your panel capacity.
