I’m wondering if the batteries are out of balance. You might need to charge 1 set alone or even individually to get them full and calibrated.
I had someone with a different kilovault have similar issues which when we charged them individually took care of the problem. And guessing it will come back at some point. The other thing I just remembered is that there are balancers from a few companies that I’d recommend ( so does kilovault). Kilovault and victron are the two that come to mind but are probably others.
