Sometimes the little battery tenders won't charge a completely dead battery. I recently bought this to replace my cheap battery tender and it has been awesome. (pricey)

I used a CTEK 7200 (https://smile.amazon.com/gp/product/B000FRLO9Y) on the Hobbit Hole and it worked great in the same setup

There are many battery conditioners that would most likely help your batteries. It is not a novice event. Most are 12v and would need to run about 20 hrs approx to break down the sulfate in the battery. If it were my system, I would disconnect every single battery and test. I am going to guess that there is a single bad battery with a single cell or 2 that is causing problems. Since the generator kicks on based on voltage, one single cell in one battery could be causing your problem.

To test, after disconnecting individual batteries they should all be reasonably close to the same voltage. Assuming they are 12v batteries each cell is 2V The batteries charged should be about 12.6 approx depending on the makeup. I am 95% sure that you will see one that is in the 10 zone. If you recondition that battery (if not able to be reconditioned replace that battery and you will be at worst back to original.

Back to the question of why does the generator kick on, it's because sulfate builds up on the plates of the batteries when the voltage drops. The battery conditioner breaks down the sulfate.
