Quick update, I spent a night at the cabin with the generator running and the SOC increased at a smooth and steady rate right to 100%. Absorb and float seems to run properly with a consistent voltage.
I’m still waiting for sunshine so I can see how the solar acts as that is the primary source of charge for the battery bank.
Thanks again to @pwfarnell @JohnC and @Josselin_Carapace for all the help with getting the proper settings for my batteries.
