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.
