CHARGING STAGES
Soft Charge (Level 1) – When batteries suffer an over-discharge, the controller will softly
ramp the battery voltage up to 10V.
Bulk Charge (Level 2) – Maximum current charging until batteries rise to Absorption level.
Absorption Charge (Level 3) – Constant voltage charging.
Equalization Charge* (Level 4) – Only for WET battery or Calcium battery type, when the
battery is deeply drained below 10V, 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).
