The last 1.5 hours gets you so little recharge with a generator and your stock charge controller.

Yes. This is inherent problem of a generator. Same noise for the last 1.5 hours and very little charge. Because batteries can't take more current.

Getting a "better" charger to bring ti faster to bulk is TAD a wishful thinking. There is a recommended limit of charging current, usually 0.25-0.3C. If your existing charger is capable of 0.3C, you should not try "improving" it because you will kill your batteries sooner.

For optimum results, a good charge controller on a single Group 24 Deep cycle battery for an hour in the morning, and a solar panel that will put out 7 to 10 amps for 5 to 8 hours daily to top charge the battery off on sunny days is a good solution to the never ending parasitic draw

An hour on generator and charger is not necessary for fridge and sensors if you have a 7-10 amp solar. 50 Ah hours daily that a mid-size solar will harvest on a sunny day, would be the energy sufficient for "living" off the solar - which is a bit higher than a "parasitic draw" that people have in storage-like conditions. My LP fridge, lights, furnace (not much), pumps, and small electronics draw 40-50 Ah in 24 hours.

Parasitic draw, even if we include LP fridge, is normally under 20 Ah. If you have a 7-10 amp solar, it will put 15-20 Ah a day in a battery even on cloudy days, so there is no need to run a generator in this scenario. Definitely no need on a sunny day.

Yes, but this is before we account for losses from it being a cloudy dark day, and running the lights longer, earlier in the evening and night, due to cloud cover, and the losses from consumption running lights, be they incandescent amp suckers or efficient LED's. I need bright light to tie nice flies to fish.
