GP-PWM-30-UL Setup & Operation: Viewing the Controller Display Information

Viewing the Controller Display Information

 

GP-PWM-30-UL has two modes to watch the display information, manual and auto scroll. 

 

You can change between the two modes by holding down the A Button for 3 seconds. 

 

 

 

 

 

Mode 1: Manually Scroll Through Display Information

 

Battery 1 Status Values

To toggle between Battery Voltage, Charging Current and Battery State of Charge (SOC) for Battery 1 and 2, press the B Button. 

 

Push the B Button to show the voltage for Battery 1. Icons Displayed: Battery SOC, Volt Symbol (V), Symbol 1

 

Push the B Button to show the PV charging current for battery 1. The GP-PWM-30-UL will begin to limit the current as Battery 1 reaches a full charge. The current that is not used for Battery 1, is used to charge Battery 2. Icons Displayed: Arrow, Ampere Symbol (A), Battery SOC, Symbol 1

 

 

The battery state of charge is shown as a percentage. Icons Displayed: Battery SOC, Percent Symbol (%), Symbol 1

 

IMPORTANT: A value of 100% will only be displayed after a Boost or Equalize charge completes. 

 

 

 

 

 

 

Battery 2 Status Values

Push the B Button to show the battery 2 voltage. Icons Displayed: Battery SOC, Volt Symbol (V), Symbol 2

 

This will only be displayed if there are two battery banks connected and battery bank 2 is connected with correct polarity.

 

 

 


Push the B Button to show the PV charging current for battery 2.

 

The GP-PWM-30-UL  will begin to limit the current as the battery 2 reaches a full charge. Icons Displayed: Arrow, Ampere Symbol, Battery SOC, Symbol 2

 

 

 


The battery state of charge is shown as a percentage. Icons Displayed: Battery SOC, Percent Symbol (%), Symbol 2

 

 

 

 

 

 


Mode 2: Automatically Change Display Information 
You can select the auto mode by holding down the A Button for 3 seconds.
The display shows the same information as in Mode 1 but changes the display automatically every 8 seconds between following information:

 

Battery 1: Voltage; PV Charging Current; Battery State of Charge (SOC)
Battery 2: Voltage; PV Charging Current; Battery State of Charge (SOC) 

 

If Battery 2 is not connected, the Controller changes only the information for Battery 1.
