1. INSTALLATION OVERVIEW 1.1 INTRODUCTION A Solar Controller (or Charge Controller / Regulator) is an essential component of your photovoltaic solar system. The Controller main- tains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the Controller prevents overcharging by limiting the current flowing into the batteries from your solar array.

3. TOOL AND MATERIALS NEEDED • Flathead Screwdriver (for wire terminals) • Philips Screwdriver (for mounting screws) • Wire Cutter /Stripper If the GP-PWM-30-UL Controller was purchased with a Go Power! RV Solar Power Kit, then UV resistant wire is included. Note For instructions regarding the Go Power! RV Solar Power Kit installation, please refer to the Installation Guide provided with the Kit.
7. WIRING DIAGRAMS Suggested Minimum Wire Gauge (Cable length 25 ft. max. from solar array to battery bank). Wire Type Wire size min (AWG) Wire size Max (AWG) Copper Only, 90°C AWG 10 AWG 4 IMPORTANT: Identify the polarity (positive and negative) on the cable used for the battery and solar module. Use colored wires or mark the wire ends with tags.
WIRING DIAGRAMS 7.1 CHARGING ONLY ONE BATTERY Use the following wiring diagram if you are using the GP-PWM-30-UL to charge only one battery. Connect your battery to the battery 1 terminals on the solar controller. The fuse or breaker used should be no larg- er than 50 amps The controller will not work unless there is a battery connected to the Battery 1 terminals.
8. OPERATING INSTRUCTIONS WARNING: When the photovoltaic (solar) array is exposed to light, it supplies a dc voltage to this equipment. 8. OPERATING INSTRUCTIONS 8.1 POWER UP When the GP-PWM-30-UL is connected to the battery, the controller will go into Power Up mode. Icons Displayed: All segments of the numerical display;...
OPERATING INSTRUCTIONS Setting Battery 2 If you have a second battery bank connected, the controller will immediately prompt you to set the battery type for Battery 2 with a blinking number 2. If there is not a second battery bank connected to the controller, or if the second battery bank is connected with reverse Note polarity, the controller will not prompt you to select battery type for Battery 2, and no status information will be displayed on the LCD screen.
OPERATING INSTRUCTIONS BATTERY TYPE SEALED/GEL FLOODED Float Charge @ 25°C: 13.7V (+/- 0.1V) Bulk/Absorption Charge @ 25°C: 14.1V (+/- 0.1V) 14.4V (+/- 0.1V) 14.4V (+/- 0.1V) Set to 30 minutes every morning. Applied for 2 hours if the battery voltage drops below 12.3 volts. Equalization Charge @ 25°C: 14.9V (+/-0.1V) Applied for 2 hours every 28 days and if the battery voltage...
OPERATING INSTRUCTIONS If sunlight is insufficient or not available, completing Max Power Boost may take much longer than 30 minutes from the Note time of the button press. Max Power Boost and the BOOST icon cannot be turned off by pressing the Max BOOST button 8.5 VIEWING THE CONTROLLER DISPLAY INFORMATION GP-PWM-30-UL has two modes to watch the display information, manual and auto scroll.

OPERATING INSTRUCTIONS The battery state of charge is shown as a percentage. Icons Displayed: Battery SOC, Percent Symbol (%), Symbol 1 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.
OPERATING INSTRUCTIONS 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;...
OPERATING INSTRUCTIONS 8.7 ERRORS OVER VOLTAGE If the GP-PWM-30-UL experiences a battery over voltage (>15.5 VDC) on battery bank 1, the controller will stop operating, and the display will begin to flash with all icons. The controller will resume operating when the voltage drops to a normal level <15.5 VDC.
9. DISPLAY SYMBOLS Battery 1 Reverse Polarity If the GP-PWM-30-UL senses reverse polarity on battery 1, the controller will stop operating, beep continuously and display POL. The controller will resume operating when the error is cleared. Icons Displayed: POL 9. DISPLAY SYMBOLS BATTERY 1 SYMBOLS INDICATOR FOR...

INVERTER CONTROL ON/OFF First, connect the inverter directly to the battery (follow the installation instructions included with the inverter). Then, connect the modular cable (found in the inverter remote box) to the re- mote terminal of the inverter and to the remote terminal of the GP-PWM-30-UL (marked with an AC Plug symbol).
11. USB CHARGING The GP-PWM-30-UL offers a standard USB connector for delivering 5.0 VDC to small mobile appliances such as cell phones, tablets and small music players. This charging port can supply up to 800 mA of current. Remove the rubber cover of the USB terminal to access the terminal. The USB charging port is active when the USB symbol appears on the display.

14. TROUBLESHOOTING PROBLEMS possibly caused by loose connections, long wire runs, small wire gauge, faulty wiring, a faulty voltmeter or all the above. Consult the Suggested Minimum Wire Gauge chart in Section 6 for wiring suggestions and check all connections. For advanced users: The GP-PWM-30-UL makes voltage measurement adjustments based on resistance it detects at the battery terminals.
TROUBLESHOOTING PROBLEMS 14.1 PROBLEMS WITH DISPLAY Display Reading: Blank Time of Day: Daytime/Nighttime Possible Causes: Battery or fuse connection and/or solar array connection (Daytime only) or battery or fuse connection (Nighttime only). How to tell: Check the voltage at the controller battery terminals with a voltmeter and compare with a voltage reading at the battery terminals. If there is no voltage reading at the controller battery terminals, the problem is in the wiring between the battery and the controller.
TROUBLESHOOTING PROBLEMS How to tell: The State of Charge (SOC) screen is close to 100% and the Sun and Battery icon are present with an arrow between. With the solar array in sunlight, check the voltage at the controller solar array terminals with a voltmeter. If there is no reading at the controller solar array terminals, the problem is somewhere in the wiring from the solar array to the controller.
