With solar and its typically low charging rate (under 10%) you can be in the 90+ percent SOC zone, but with a better charging rate you will not be close. Even so it takes a long time to get from 90 to 100.
EG, at the 20% charging rate specified for the Bulk stage with AGMs amps will start to taper at about 75% SOC--a long way from being fully charged.
What about LiFePO4 banks? Can't assume everyone is using FLA or AGMs any more.
