GP-PWM-10-FM 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-FM 1.4 Low Voltage Disconnect Function (USB Port) To protect the battery against over-discharge this function automatically switches off the USB output port when battery voltage is lower than 11.0 VDC. As soon as the battery reaches a voltage of 12.8 VDC the USB output port is switched on again. 1.5 Regulatory Information 1.6 Specifications Description Model Nominal System Voltage Range of Battery Input Value GP-PWM-10-FM 12 VDC 12.5 ADC 9 – 14.

La tension qui en résulte ne doit pas excéder 35 V. Si votre système solaire dépasse cette valeur, veuillez contacter votre revendeur pour obtenir un régulateur plus approprié. 3.
GP-PWM-10-FM 5.0 Installation Instructions 1. Prepare for mounting. Use the template provided on page 27 to mark the four mounting holes and the cutting line for flush mounting your controller. 2. Complete the installation of the solar modules. If this GP-PWM-10-FM was purchased as part of a Go Power! Solar Power Kit, follow the Installation Guide provided. Otherwise, follow manufacturer’s instructions for solar module mounting and wiring.
GP-PWM-10-FM 3. Select wire type and gauge. If this GP-PWM-10-FM was purchased as part of a Go Power! Solar Power Kit, appropriate wire type, gauge, and length is provided. Please continue to Section 6, “Operating Instructions.” If the GP-PWM-10-FM was purchased separately, follow the instructions included here. Wire type is recommended to be a stranded copper UV-resistant wire. Wire fatigue and the likelihood of a loose connection are greatly reduced in stranded wire compared to solid wire.

Torque all terminal screws per the following: Stranded Copper 90°C Wire Wire Size AWG 14 12 10 Rated Torque (in-lbs) 20 20 20 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-FM 6.0 Wiring Diagram IMPORTANT: This diagram is valid only for version 1.5 and newer. Version 1.4 and older have different terminal locations. The GP-PWM-10-FM Maximum 12.5A rating is based on a 10 amp total maximum short circuit current rating (Isc) from the parallel solar modules nameplate ratings. The National Electric Code specifies the PV equipment/system rating to be 125% of the maximum Isc from the PV module nameplate ratings (1.25 times 10 = 12.5A).
GP-PWM-10-FM 7.0 Operating Instructions 7.1 Power Up When the GP-PWM-10-FM 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-FM Power Up occurs, the controller may do a Boost Charge or quickly go into Float Charge. The Charging Profile selected will commence the following day after a Power Up (refer to the Charging Profile Chart on page 11 for more details).

This charging port is capable of supplying up to 1500 mA of current. Remove the rubber cover of the USB terminal to access the terminal.
GP-PWM-10-FM It seems like my flooded batteries are losing water over time. Flooded batteries may need to have distilled water added periodically to replace fluid loss during charging. Excessive water loss during a short period of time indicates the possibility of overcharging or aging batteries. When charging, my flooded batteries are emitting gas. During charging, hydrogen gas is generated within the battery. The gas bubbles stir the battery acid, allowing it to receive a fuller state of charge.
GP-PWM-10-FM Why does the battery SOC% never reach 100%? A 100% value will only appear after a 2 hour Boost or Equalize charge has completed. The charge voltage must be maintained for an extended period of time to replenish the energy in the battery bank back to its rated capacity. If the charge voltage cannot be maintained continuously, then the actual time it takes to complete Boost or Equalize charging may take much longer than 2 hours, even more than 1 day.
GP-PWM-10-FM 2. If there is no voltage reading at the controller battery terminals, the problem is in the wiring between the battery and the controller. If the battery voltage is lower than 6 volts, the controller will not function. 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-FM 2. If there is a voltage discrepancy of more than 0.5 VDC, there is an excessive voltage drop. 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. two wire runs) to simulate a larger gauge wire.
GP-PWM-10-FM Possible Cause: Current is being limited below 1 Amp as per normal operation or poor connection between solar array and controller. How to tell: 1. The State of Charge (SOC) screen is close to 100% and the Sun and Battery icon are present with an arrow between. 2. With the solar array in sunlight, check the voltage at the controller solar array terminals with a voltmeter. 3.
GP-PWM-10-FM (3) Modules look dirty, overhead object is shading modules or it is an overcast day in which a shadow cannot be cast. Avoid any shading no matter how small. An object as small as a broomstick held across the solar module may cause the power output to be reduced. Overcast days may also decrease the power output of the module. (4) Disconnect one or both array wires from the controller. Take a voltage reading between the positive and negative array wire.
