Upon further investigation this generator/converter setup does include option C (charger). So my battery does charge when the genset is running (and plugged in in the back). The only two things that haven't been run to test is the water system (too close to winter to mess with it and then the subsequent re-winterizing) and the Norcold 770 EG2 refrigerator running on propane. I still cannot get this cranky old girl to fire up on LP. ONCE, just once, there was a small puff of mostly yellow flame in the sight glass, but nothing since. Looks like this weekend I'll have to do some cleaning and maintenance on the burner orifice to make sure that isn't the issue. It runs nice and cold on 120v, though.
