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 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

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).
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.

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 possiblycaused 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?
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
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%.
