Bought my used camper last year and a solar panel was already installed when I got it. My last camping trip I ran the heater overnight for two nights with no problems and was camped under trees so do...
Don't have any specs for the panel, but it is 2' x 4' in size. I have to take my wife in for a medical procedure now but will check back in tonight. Thinking I check voltage again tonight and disconnect batteries overnight and see what voltage they stabilize at in the morning. There is a series resistor in the charging circuit so am guessing once the charging current drops to a low enough level it should switch to float mode.
