OPERATING INSTRUCTIONS
Absorption charging
Float charging
Solar panel weak
At night no charge
WET CELL BATTERY CHARGING ALGORITHM
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 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.

Auto Equalize: The GP-PWM-10-SQ has an automatic
equalize feature that will charge and recondition your bat-
teries 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 manu-
facturer. This feature is only available for wet cell or flooded
batteries
