The unit has a 5 stage charging algorithm.
Soft Charge (Level 1) –Bulk Charge (Level 2)-Absorption charge (Level 3) –
Equalizing Charge* (Level 4) - Float Mode (Level 5)
Soft Charge
- When batteries suffer an over-discharge, the controller will softly ramps
the battery voltage up to 10V.
Bulk Charge
-Maximum current charging until batteries rise to Absorption level
Absorption Charge-
Constant voltage charging and battery is over 85%.
Equalization Charge*
-Only for WET battery or Calcium battery type, when the battery
is deeply drained below 11.5V, it will automatically run this stage to bring
the internal cells as an equal states and fully complement the loss of
capacity.(Gel and AGM battery do not run Equalization charge)
Float Charge
-Battery is fully charged and maintained at a safe level.
A fully charged battery has a voltage of more than 13.6 Volts.
