How big of a generator do I need to charge up my battery enough to run the lights. I found one on sale for 100.00 but I am not sure if it is strong enough and I am not even sure what I am looking at....
I would go with about a 2000 watt. This will allow you to use some other 120 volt items, like microwave and TV. Verify your converter size. You could post make and model if you are unsure of the 120 volt maximum draw. I am guessing you have about a 45 amp converter.
