You went below the orange line so the solar ran at max voltage all day with no float.
That is all you can do except to add more solar.
IIRC I think my lines are drawn at 12.5 and 12.0
I am leaning towards possible overcharging being less harmful than sulphation. Plus, I did observe charging Amps over quite a while to try to achieve the one-half of one percent rule from Lifeline's manual. I don't have Lifeline. Mine are bought used at 5+ years old.
Yes, it should run all day today in bulk or abs, and no float. I doubt that the battery will be above the 12.4V line overnight and the float will be cancelled tomorrow as well. This will repeat until the missing Ahs are restored.
The 148Ahs showing yesterday were not enough to overcome the draw down. I let the A/C run until, at 10.9V, the inverter shut down.
The batteries were willing but the inverter was weak. :)
