The charger is drawing about 84 watts (120 VAC times 0.7 amps), but only delivering about 41.4 watts (~13.8 VDC times 3 amps). Plus the TV and lights, it’s a losing proposition.
Suggest just using the inverter to power the TV and lights, add another battery if the one is not enough. Going by your values I’m guessing you are already using fluorescent lights and a LCD TV for lower power drain?
Yes, fluorescent lights and lcd. Here is the battery I am using.

I want to believe it has enough capacity to get through the few hours at night running the inverter and the charger charging enough not to kill the battery until I fire up the generator the next day and the charger can work off the generator. Thanks!
