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 water come into contact with the controller.

5. GP-PWM-10-FM/GP-PWM-30-SB SOLAR CONTROLLER
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 owing 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.
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 eld.
