Charging from the generator is my biggest concern. When I get home I just plug the RV into the house and the batteries get their charge for next time, but when out in the sticks I need to recharge the batteries as quickly as possible without running a 4000 watt generator for 5 hours. Why is the charging different when running the genset compared to being plugged into a house outlet? Does the 4K gen not put out enough juice? Or did they wire it up differently? I was under the impression that the converter/charger does not know where the 120v is coming from (house or generator) and that it converts and charges the same either way?
