Hi, i want to know how many time i must set on my mppt charger for the absoption phase : i have 2 battery gel 110ah // > 220ah
all days, my controleur when the sun is up, do an absoption phase (i's set it for 30mn) and after this 30 mns, the float phase is automatic.
30mn, is too long? too short? ...
regards.
