A] consistent current (CC) charging
During CC charging, if the battery voltage hasn’t yet reached the set value
of charged voltage, the charger will charge the battery with maximum
MPPT Solar energy capacity. When the battery voltage reaches the pre-
set value, charging at consistent voltage will start.
B ] consistent voltage (CV) charging
During this phase in the charging process no MPPT charging is used.
During this phase the charging current will gradually reduce. The
consistent voltage charging consists of two sub-phases, i.e. equalizing
charging and boost charging. These two phases are not executed
