Page 4: Installation Overview
1. INSTALLATION OVERVIEW 1.1 INTRODUCTION A Solar Controller (or Charge Controller / Regulator) is an essential component of your photovoltaic solar system. The Controller maintains 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. - Page 5 INSTALLATION OVERVIEW Temperature compensation range -20~+50 °C Operating Temperature - 20 to 50°C / - 13 to 122°F Over temperature protection during charging 65 °C Storage temperature - 40 to 85°C / -40 to 185°F Transient over voltage protection with TVS or varistor Power terminal max stranded wire size #12 AWG stranded -3mm Mounting...

Page 6: Warnings
2. WARNINGS Electricity can be very dangerous. Installation should be performed only Disconnect all power sources by a licensed electrician or qualified personnel. Observe all safety precautions of the battery manufacturer when handling Battery and wiring safety or working around batteries. When charging, batteries produce hydrogen gas, which is highly explosive. -
Page 7: Choosing A Location
3. CHOOSING A LOCATION The GP-PWM-10-SQ is designed to be mounted against a wall, out of the way but easily visible. The GP-PWM-10-SQ should be: • Mounted as close to the battery as possible • Mounted on a vertical surface to optimize cooling of the unit •... -

Page 11: Problems With Voltage
OPERATING INSTRUCTIONS 7.2 PROBLEMS WITH VOLTAGE Voltage Reading: Inaccurate Time of Day: Daytime/Nighttime Possible Causes: Excessive voltage drop from batteries to controller due to loose connections, small wire gauge or both. How to tell: Check the voltage at the controller battery terminals with a voltmeter and compare with the voltage reading at the battery terminals. If there is a voltage discrepancy of more than 0.5 V, there is an excessive voltage drop. -
Page 12: Wiring Diagram
8. WIRING DIAGRAM Disconnect one or both array wires from the controller. Take a voltage reading between the positive and negative array wire. A single 12 volt module should have an open circuit voltage between 17 and 22 volts. If you have more than one solar module, you will need to conduct this test between the positive and negative terminals of each module junction box with either the positive or the negative wires disconnected from the terminal. -
