WARNINGS

| Disconnect all power sources| Electricity can be very dangerous. Take appropriate caution when making connections.
---|---|---
| Battery and wiring safety| Observe all safety precautions of the battery manufacturer when handling or working around batteries. When charging, batteries produce hydrogen gas, which is highly explosive. Ensure batteries are in a well-ventilated space, away from sparks for open flames.
| Wiring connections| Ensure all connections are tight and secure. Loose connections may generate sparks and heat. Be sure to check all connections before using the portable solar kit.
| Observe correct polarity| Reverse polarity of the battery terminals and array will cause the controller to give a warning tone. The controller will not function unless battery terminals are connected to a battery with proper polarity. Failure to correct this fault could damage the controller.
| Do not exceed the Charge Controller current and voltage ratings| Refer to the charge controller manual for details.
| Do not leave the device outside in inclement weather or rain, or unattended| This kit is not weatherproof. Never leave your Portable Solar Kit unattended, plugged in overnight, or subject to inclement weather.

30’ Extension Cable – Park your RV in the shade and place your solar panel in the sun using this extension cable.

 INSTALLATION

1.  Locate a sunlit area, free from overhanging branches or obstructions.
2. Remove solar panel kit from carrying case.
3. Unclip the two latches on the side of the unit and fold the two panels outward. Extend the two support legs to their maximum length and lock in position.
4. Place solar panel facing the sun.

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 cut the power output of the module. To obtain maximum output it is suggested that the panel’s direction be frequently adjusted to track the sun’s movement throughout the day (southerly exposure).

5. Connect battery clamps to the positive (red, +) and negative (black, -) battery terminals. Ensure that the connection is secure. Connect the battery clamp cable to the rest of the solar panel cable using the quick-connect cable.

Ensure the battery clamps do not come in contact with one another. Do not let the water come into contact with the controller.

GP-PWM-10-FM/GP-PWM-30-SB SOLAR CONTROLLER

 INSTALLATION OVERVIEW

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.
The GP-PWM-10-FM AND GP-PWM-30-SB use Pulse Width Modulation (PWM) technology and a unique four-stage charging system that includes an optional equalize setting to charge and protect your battery bank. Both controllers feature an LCD digital display that shows the charge current of the solar array, battery voltage, and battery state of charge.

 VOLTAGE AND CURRENT SYSTEM

The GP-PWM-10-FM and GP-PWM-30-SB are intended for use at 12 VDC nominal system voltage and is rated for a maximum continuous DC input current of 12.5A and input voltage of 35VDC.
Per the National Electric Code (NEC) article 690.7 and 690.8, PV module nameplate ratings at Standard Test Conditions (STC) must be multiplied by required values (typically  1.25 for both voltage and current) to obtain the true voltage and continuous current available from the module.
Applying the NEC factors, the maximum allowable nameplate PV Panel rated Isc is 10A (10A x 1.25 = 12.5A), and the maximum voltage, Voc is 28VDC (28VDC x 1.25 = 35VDC).
The voltage and current ratings of all equipment connected to PV panels must be capable of accepting the voltage and current levels
available from PV panels installed in the field.

 BATTERY TYPE

Both controllers are suitable for use with lead-acid and lithium batteries (vented, GEL, LiFePO4 (LFP) or AGM type).

5.1.4 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.

5.2 IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INSTRUCTIONS FOR MODEL GP-PWM-10-FM and GP- PWM-30-SB THAT SHOULD BE FOLLOWED DURING INSTALLATION AND MAINTENANCE OF EITHER CONTROLLER

| Disconnect all power sources| Electricity can be very dangerous. Installation should be performed only by a licensed

an electrician or qualified personnel..

---|---|---
| Battery and wiring safety| Observe all safety precautions of the battery manufacturer when handling or working around batteries. When charging, batteries produce hydrogen gas, which is highly explosive. Ensure batteries are in a well-ventilated space, away from sparks for open flames.
| Wiring connections| Ensure all connections are tight and secure. Loose connections may generate sparks and heat. Be sure to check all connections one week after installation to ensure they are still tight.
| Work safely| Wear protective eyewear and appropriate clothing during installation. Use extreme caution when working with electricity and when handling and working around batteries.
| Observe correct polarity| Reverse polarity of the battery terminals and array will cause the controller to give a warning tone. The controller will not function unless battery terminals are connected to a battery with proper polarity. Failure to correct this fault could damage the controller.
| Do not exceed the GP- PWM-10-FM Amp current and max voltage ratings| The maximum current of the solar system is the sum of parallel-connected PV module–rated short circuit Currents (Isc) multiplied by 1.25. The resulting system current is not to exceed 12.5A. If your solar system exceeds this value, contact your dealer for a suitable controller alternative.
| Do not exceed the GP- PWM-10-FM max voltage ratings| The maximum voltage of the array is the sum of the PV module–rated open-circuit voltage of the series-connected modules multiplied by 1.25 (or by a value from NEC 690.7 provided in Table 690.7 A). The resulting voltage is not to exceed 35V. If your solar system exceeds this value, contact your dealer for a suitable controller alternative.

5.3 OPERATING INSTRUCTIONS

 USB CHARGING

The GP-PWM-10-FM and GP-PWM-30-SB offer a standard USB connector for delivering 5.0 VDC to small mobile appliances such as cell phones, tablets or small music players. 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.
The USB charging port is always active when the USB symbol appears on the display.
The controller disables the USB charger automatically if the battery voltage drops below 11.0 VDC. If there is enough current from the PV panel/array available to charge the Battery to above 12.8 VDC, the USB terminal will be enabled again.

WARNING: Do not connect the charging device anywhere else! USB-Negative contact is connected to battery negative.

FREQUENTLY ASKED QUESTIONS

Before a problem is suspected with the system, read this section. There are numerous events that may appear as problems but are in fact perfectly normal. Please visit gpelectric.com/support for the most up-to-date FAQs.
Q. It seems like my flooded batteries are losing water over time.
A. 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.
Q. When charging, my flooded batteries are emitting gas.
A. 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. Important: Ensure batteries are in a well-ventilated space.
Q. My voltmeter shows a different reading than the GP-PWM-10-FM display.
A. The meter value on the GP-PWM-10-FM display is an approximate reading intended for indication purposes only. There is an approximate 0.1-volt inherent error present that may be accentuated when compared with readings from another voltmeter. There may be a slight difference between the battery voltage displayed on the GP-PWM-10-FM 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-FM controller terminals and battery voltage at the battery terminals. If a difference of more than 0.5 volts is noted, this indicates a large voltage drop possibly caused by loose connections, long wire runs, small wire gauge, faulty wiring, a faulty voltmeter, or all the above.

Q. What causes a warning signal and when are the warnings triggered?

Battery reverse polarity

|

“POL” on LCD and constant audible alarm

| |

PV reverse polarity

|

“POL” on LCD and constant audible alarm

|

The battery must be connected with correct polarity

|

Q. Why does the battery SOC% never reach 100%?
A. A 100% value will only appear after a 2-hour Boost or Equalize charge has been 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. If loads are consuming more power than the solar panels can supply, then the battery bank cannot be charged to 100%.
