I have a 48V-560AH LiFePO4) battery bank (2-EVE 280 cells in parallel , 16 series) solar only charging and float set to 54.5. I notice that within 30 mins of sun going down and no load (other than tare loss of inverters ~75W) that the voltage drops from 54.5 down to 53.8 and then levels out. See graph of battery voltage for yesterday below.
So is it normal for LiFePO4 or indicative of a problem with my battery bank?
Are the voltage/SOC curves and tables, like the one below , indicative of when the battery is at rest or under charge or shouldn't it matter.
