GP-PWM-10 _________________________________________________________________________________ 12.0 Limited Warranty 12.1 Repair and Return Information 1.0 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.

GP-PWM-10 _________________________________________________________________________________ 2.0 Warnings Electricity can be very dangerous. Installation Disconnect all should be performed only by a licensed power sources electrician or qualified personnel. Observe all safety precautions of the battery Battery and manufacturer when handling or working around batteries. When charging, batteries wiring safety produce hydrogen gas, which is highly explosive.
GP-PWM-10 _________________________________________________________________________________ 4.0 Choosing a Location The GP-PWM-10 is designed to be mounted against a wall, out of the way but easily visible. The GP-PWM-10 should be: • Mounted as close to the battery as possible • Mounted on a vertical surface to optimize cooling of the unit •...

GP-PWM-10 _________________________________________________________________________________ Wire Strip Gauge You will find a strip gauge diagram on the back of the GP-PWM-10, which helps you to strip your wires to the correct length. Insert wire into the concave slot of the strip gauge until it meets the back of the Strip Gauge slot.
GP-PWM-10 _________________________________________________________________________________ With battery power attached, the controller should power up and display information. Connect the solar wiring to the controller and remove the opaque material from the solar array. The negative solar array and battery wiring must be connected directly to the controller for proper operation.
GP-PWM-10 _________________________________________________________________________________ 7.0 Operating Instructions 7.1 Power Up When the GP-PWM-10 is connected to the battery, the controller will go into Power Up mode. Icons Displayed: All segments of the numerical display; Backlight blinks Depending on the battery voltage when the GP-PWM- 10 Power Up occurs, the controller may do a Boost Charge or quickly go into...
GP-PWM-10 _________________________________________________________________________________ To confirm the battery profile, press and hold the A Button for 3 seconds. Non-volatile memory: Any settings made on the GP- PWM-10 will be saved even when the power has been disconnected from the controller. Refer to the Battery Charge Profile Chart below for details on each profile.
GP-PWM-10 _________________________________________________________________________________ Auto Equalize: The GP-PWM-10 has an automatic equalize feature that will charge and recondition your batteries once a month at a higher voltage to ensure that any excess sulfation is removed. This feature is only available when Flooded batteries are selected.

GP-PWM-10 _________________________________________________________________________________ The controller disables the USB charger automatically if the battery voltage drops below 11.0V. If there is enough current from the PV panel/array available to charge the Battery to above 12.8V, the USB terminal will be enabled again. Warning: Do not connect the charging device anywhere else! USB-Negative contact...
GP-PWM-10 _________________________________________________________________________________ There may be a slight difference between the battery voltage displayed on the GP-PWM-10 display and the battery voltage measured at the battery terminals. When troubleshooting using a voltmeter, check both the battery voltage at the GP-PWM-10 controller terminals and battery voltage at the battery terminals.
GP-PWM-10 _________________________________________________________________________________ 3. For the solar array, repeat steps 1 and 2 substituting all battery terminals with solar array terminals. Remedy: Check all connections from the controller to the battery including checking for correct wire polarity. Check that all connections are clean, tight, and secure.
GP-PWM-10 _________________________________________________________________________________ Remedy: Check all connections from the controller to the battery including checking for correct wire polarity. Check that all connections are clean, tight, and secure. Shorten the distance from the controller to battery or obtain larger gauge wire. It is also possible to double up the existing gauge wire (i.e.
