Based on last thread and now this, the first thing to do is toss that controller. :) Perhaps a good replacement would be that Grape 40 that has neat features at low cost, like Mr Wizard got.
Everyone has his own way to RV.
Not clear from OP, have to "be there" and see I guess, but it sounds like things could be improved (less gen time) just by getting a 2000w inverter. That will run from the four batteries ok. Use that to run the microwave etc, instead of the generator. Then get more solar to bring the batts up before dark. We do all that with 300w of solar, only use the gen if no sun for a couple days.
Shouldn't need to goose the batts in the evening to get by till morning. That seems strange to me. Depends on what draws there are at night of course.
