Can Experienced and/or Expert RVers Advise Me About Battery Charging
In reading your original post I see that you have two group 24 batteries. This size battery doesn't have much capacity to carry typical trailer power loads for very long, especially if the batteries are not brand new. As others have said, you'll need to run your generator a couple of hours a day to keep the group 24's charged. If you want to run your generator less, when the group 24 batteries need to be replaced I would suggest upgrading to at least group 27 or group 31 batteries. You may also want to consider going to two large 6-volt golf cart batteries wired in series. The idea is to get higher ampere-hour rated batteries.
I have one 140-watt solar panel on my 24-foot trailer and an 8-amp charge controller. As long as the days are sunny this is plenty to keep my two 6-volt 8AGC2 AGM golf cart batteries charged up, without my needing to run a generator at all. In fact I can go two or three days without needing to run the generator, even when the skies are cloudy. This assumes I don't need to run the furnace, which is a true power hog! The 8AGC2 batteries could carry the load even longer, but it is best to not let AGM batteries drop below about 50% of their operating voltage range in order to get long life out of them. I do have a 1,000 watt Westinghouse inverter generator in case there are several cloudy days in a row. When plugged into shore power or using the generator my trailer has an Iota DLS-30 with an IQ-AGM module to keep the batteries charged.
I'm not a full-timer, but my wife and I do spend a couple of months a year in Arizona and southern California, boondocking for about half of that time. I converted my trailer lamps all to LEDs, and that made a HUGE difference in how long the battery lasts before needing to be recharged!
Best of luck in your quest for quiet boondocking!
