Wet Cell Battery Charging Algorithm
Auto Equalize:
The GP-
PWM-30-SQ has an automatic
equalize feature that will
charge and recondition your
batteries once a month at a
higher voltage to ensure that
any excess sulfation is
removed. This feature is recommended for Flooded batteries only. Check with your battery
manufacturer. This feature is only available for wet cell or flooded batteries.
Soft Charge
- When batteries suffer an over-discharge, the controller will softly ramp 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 (Flooded lead acid) 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 state and fully complement the loss of capacity. (LTO, Gel, Life P04 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. A fully charged Life P04 battery has a voltage level of 14.6V.
LTO has a voltage level of 13.4V.
