to 100A in small increments on the inverter’s LCD. This is helpful if this powerful charger applies charging to a small
capacity battery bank.
There are mainly 3 stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with
controlled constant current. The charger will remain in Bulk charge until the absorption charge voltage is achieved.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached. Absorb
charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the
absorb voltage setting.
In this period，the inverter will start a T1 time; the charger will keep the boost voltage in Boost CV mode until the T1
time has run out. When charging current is <0.01C or the time is over 12 hours, then drop the voltage
Down to the float voltage.
Float Charging: The third charging stage occurs at the end of the absorb charging time. During float charging, the
charge voltage is reduced to the float charge voltage. In this stage, the battery are kept fully charged and ready if
needed by the inverter.
