I agree that since you have the generator, upgrade the converter so you can get a good most-of-the-way charge with it in a relatively short time.
But also put 200-400 watts of solar on the roof and you may never need the gen. It will be available "in case of emergency".
I have a generator but chose to put 280 watts of solar on the roof with plan for expansion. I thought the converter upgrade would come later. The result has been that the 280 watts of solar works just fine for keeping up with our needs with long weekend-style boondock camping. Generator usually gets brought along but never used. Our camper pretty much never sees true shore power, solar keeps things bursting full when stored at home. Still have the WFCO converter installed (in case of emergency).
