GP-PWM-30-SQ

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 softl

y ramp the battery

voltage up to 10V.

lk 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.
