Section 6: Multistage Charging
The Prosine inverter/charger has a fully functional multistage battery charger. Any time an acceptable (within frequency and voltage parameters) AC source is presented to the unit, it will charge the batteries connected to it. When AC is present and the charger is enabled, the charger will charge the battery bank regardless of the position of the inverter’s On/Off switch.

Bulk Charge
In the first step, known as the bulk charge, the Prosine inverter/charger delivers the maximum charge current allowable given the configuration settings, that is, battery type and temperature, maximum AC input setting and battery bank size. This current is delivered to the batteries until the battery voltage approaches its gassing
Absorption Charge
During the absorption charge, the charging voltage is held constant near the gassing voltage and the charging current is steadily decreased. When the charging current has decreased to a predetermined
