Alright, then you don’t need to push it to 95%. They are happier when staying in 20-80% range.

Correct the batteries don't need to be in the 95%+ range which after overcast/ snow or just poor solar days and knowing that the weather will be better for replenishing the batteries. The system was installed so I could go 3 days with full convenience without having to hook up the generator for a hold over charge till the sun shines again. The lowest the batteries have been down in the morning while still using the microwave or coffee maker is 24% (120ah).
I know how my setup works after 18 months which is why I was wondering why it wasn't recovering as normal and something so simple as the tv antenna that I never thought about or at least had an impact is it did at this location and time of year.
Without going in to detail with these fully programmable inverter/ charges working in unison of the solar controller the bms is not controlling shut down other than programed
adverse condtions.
