GP-PWM-10-FM/GP-PWM-30-SB SOLAR CONTROLLER
When the GP-PWM-10-FM or GP-PWM-30-SB are connected to the battery, the controller will go into Power Up mode.
Icons Displayed: All segments of the numerical display; backlight blinks.
(The diagrams on the following pages apply to both the GP-PWM-10-FM and the GP-PWM-30-SB).
Depending on the battery voltage when the controller Power Up occurs, the controller may do a Boost Charge or quickly go into Float Charge.
The Charging Prole selected will commence the following day after a Power Up (refer to the Charging Prole Chart below for more details).
To select the battery charging prole, press and hold the B Button. This will cause
the current battery type to ash.
Then, press the B Button to toggle through the prole options: Sealed/Gel, AGM/
LiFePO4 or Flooded.
To conrm the battery prole, press and hold the A Button for 3 seconds.
Non-volatile memory: Any settings made on the GP-PWM-10-FM will be saved
even when the power has been disconnected from the controller.
Refer to the Battery Charge Prole Chart below for details on each prole.
BATTERY TYPE SEALED /GEL AGM FLOODED LFP
Float Charge @ 25°C: 13.7V (+/- 0.1V) N/A
Bulk/Absorption Charge @ 25°C:
Set to 30 minutes every morning.
Applied for 2 hours if the battery voltage
drops below 12.3 volts.
14.1V (+/- 0.1V) 14.4V (+/- 0.1V) 14.4V (+/- 0.1V) N/A
Equalization Charge @ 25°C:
Applied for 2 hours every 28 days and if
the battery voltage drops below
12.1 volts.
N/A N/A 14.9V (+/-0.1V) N/A
Absorption Charge voltage for LiFe-
PO4:
Set to 30 minutes every morning
N/A 14.4VDC
Float Charge voltage for LiFePO4: N/A 14.0VDC
If a charging cycle is unable to complete in a single day, it will continue the following day. The terms SEALED/GEL, AGM, FLOODED and LFP are
generic battery designations. Choose the charging prole that works best with your battery manufacturer’s recommendations.
If PV power is insu󰀩cient or too many loads are drawing power from the battery, the controller will not be able
to charge the battery to the target charging voltage.
