Note
2.1 HOW DOES A GO POWER! SOLAR CHARGING KIT WORK?
The solar panel converts the sun’s energy into DC electricity and this electricity charges the battery. The battery stores the
electricity, similar to a water tank storing water. This battery power may be used at any time to operate DC powered devices con-
nected to the battery. To increase the battery service life, a solar controller is used to prevent the solar panels from overcharging
the batteries. This is process is managed by the Solar Charge Controller included in this kit. See Figure 2-A (below) and 2-B (on
following page) for solar system examples.

GENERAL INFORMATION
2.2 CAUTIONS
Note
Disconnect all power sources
before attempting installation
Electricity can be very dangerous. It is critical that the electrical layout and
installation of the photovoltaic system be completed by an electrician or quali-
ed personnel and in compliance with the detailed procedures in this manual.
Solar panel safety
Photovoltaic panels generate DC electricity when exposed to sunlight or other
light sources. Contact with the electrically active parts of the panel, such as
terminals, can result in burns, sparks and lethal shock whether the panel is
connected or disconnected.
When panels are connected in parallel, amperages are additive. Consequently,
a system assembled from photovoltaic panels can produce high amperages,
which constitute an increased hazard. Do not touch terminals while panel is
exposed to light. Cover the panel face completely with opaque material to halt
the production of electricity when installing or working with panels or wiring.
Systems must be handled with extreme caution — failure to do so may
result in possible injury or death.
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. Work in a well ventilated area and use caution when
making or removing electrical connections. Ensure wires are disconnected from
their power sources when wiring. Do not expose battery to open ame, cigarettes
or sparks. Shield skin and eyes from battery acid. Cable leads should not be
crossed or shorted together. If shorting occurs, completely cover the panel with
a dark, light-proof material BEFORE disconnecting the cables. Modules must
not be connected or disconnected when there is a current source attached, or
when the module is exposed to light.
Ensure all connections are tight and secure. Loose connections may generate
sparks, heat and in extreme cases may catch re. Be sure to check connections
one week after installation to ensure they are still tight.
Work safely
Wear protective eye wear and appropriate clothing during installation. Use
extreme caution when working with electricity and when handling and working
around batteries. Use properly insulated tools only.
Do not carry the panels by the junction box or by the electrical cables. Do not
walk on the panels. Do not handle or install modules when they are wet or in
windy conditions. Do not allow standing water to accumulate on the module.
Go Power! recommends a minimum cable bend radius equal to or greater
than 40 mm (1.5”).
Observe correct polarity
at all times
Reverse polarity of the battery terminals will cause the controller to give a
warning tone. Reverse connection of the array will not cause an alarm but
the controller will not function. Failure to correct this fault could damage the
controller.
Do not exceed the voltage
and current ratings of the
Solar Controller
The total current of the solar system is the sum of the short circuit current of
the solar panels in parallel, multiplied by a safety factor of 1.25. The resulting
system current is not to exceed the amperage rating of the controller. The
voltage of the array is the rated open circuit voltage of the solar panels and is
not to exceed 28volts.
The current rating of the solar system is the sum of the Maximum Power Cur-
rent (Imp) of the solar PV strings in parallel. The resulting system Imp current
is not to exceed 30A. If your solar system exceeds these ratings, contact your
dealer for a suitable controller alternative.

3. PLANNING LOCATIONS
3.1 PLAN YOUR SOLAR SYSTEM SETUP
1. Take a few minutes before commencing any installation work to layout your solar system on paper rst. Use the diagrams
within this manual to help.
2.
Complete a simple block diagram identifying the key components and connections of your Solar charging system: Solar Panels,
MC4 Positive and Negative Extension Cables, Solar Charge Controller and your Battery Bank as detailed in the diagrams.
3. Identify and prepare easy/safe access to possible installation locations in the 3 key installation areas within your RV;
• Roof Solar Panels
• Instrument/Controls Solar Charge Controller and/or Inverter Remote
• Storage Compartments Inverter, Converter/Charger, Transfer Switch
4. Identify on your RV if you have a Cable Entry Plate (GP-CEP) see Fig 3-A pre-installed by
the RV Manufacturer. The Cable Entry Plate makes the Solar Panel to Solar Charge Con-
troller installation simpler. (After market purchase of GP-CEP available)
5. If you do not have the Cable Entry Plate pre-installed on your RV. You will be following the
‘Routing Power Cable through the Refrigerator Vent’ steps.
6. Whilst on the roof of your RV identify the refrigerator vent and investigate the vent-fastening
hardware.
3.2 PLACEMENT OF SOLAR PANELS
Solar modules should be installed strictly in accordance with the instructions provided in this manual. The structure on which the
module is attached must be completely rigid and remain so in all weather conditions, such as extreme winds or heavy snow. In
the case of marine applications, structures must remain rigid in heavy storm conditions and be impervious to long-term saltwater
exposure.
Solar panels will not stay exible once xed to the mounting surface. Bending or exing of the mounting surface can result in re
and/or permanently damage the solar module components.
BEFORE GLUING SOLAR PANELS - you must carefully position all solar panels BEFORE applying adhesives. Once panels are
glued to the supporting structure, they cannot be repositioned.
UTILIZATION — We strongly recommend the use of ame retardant and chemically resistant cables, especially in marine envi-
ronments or in other extreme operating conditions.
1. Remove all solar panels from their boxes. Set aside the boxes as they will be used in the instructions to follow.
2.
Using the solar panel boxes, plan the layout of the panels on your RV rooftop. Please use the notes below to help select
the best panel location(s)
• Placement of the panel(s) should be as close together as possible. Each panel has 3.3’ of cable coming from the
junction box. It may be necessary to use solar panel extension cables. If required, longer extension cables can be
purchased. Please contact customer service at 1.866.247.6527 to purchase.
• Select a location where the mounting surface is at least 1/2” thick and strong enough to support the solar panel
mounting hardware.
• Solar panels should be located a minimum of 3’ from the front of RV to reduce wind load on the panels.
• Avoid internal wiring when selecting the solar panel mounting locations for drilling the mounting holes.
• Ensure xed obstacles, such as air conditioners, will not shade the solar panels. (Shading can greatly reduce the
performance of the solar system).

3.3 LOCATING THE GP-PWM-10 OR GP-PWM-30 SOLAR CHARGE CONTROLLER
The GP-PWM-10 or GP-PWM-30 is included in all Go Power! RV Solar Kits detailed in this manual except for the expansion
kits (50E and 100E). The GP-PWM provides the necessary protection for the RV battery system. A condensed version of the
installation instructions appear in this manual. However, please read the full installation manual included with the GP-PWM-10
or GP-PWM-30 Solar Charge Controller.
1. Plan where the Solar Charge controller will mount, see Figure 3-B.
•
The Solar Charge Controller is designed to be mounted vertically in an indoor location inside a weatherproof
enclosure.
• Ideally the Solar Charge Controller should be located so it can be easily seen for monitoring system operation.
• The location will need access to the cable ends from the solar panels and the battery compartment.
WARNING: Failure to secure the Solar Charge Controller could cause it to become dislodged while the RV is
in transit and cause severe damage to the unit and/or the RV.
Note

4. INSTALLATION
4.1 SOLAR PANELS
WARNING: Photovoltaic panels generate DC electricity when exposed to sunlight or other light sources.
When exposed to light, contact with the electricity active parts of the panel, such as terminals, can result in
burns, sparks and lethal shock whether the panel is connected or disconnected.
Do not touch the terminals while the panel is exposed to light. Cover the panel faces completely with an opaque material
to stop the production of electricity when working with panels or wiring – the cardboard shipping boxes are the perfect
option to cover glass surface of the panels.
Panels are not recommended to bend beyond 30° (for 100W Modules, 30° = 2.7”, 69mm Bend)
Site Considerations — Excluded Operating Environments
Certain extreme operating environments are not recommended for Go Power! products and are excluded from the Go Power!
limited warranty. These include (but are not limited to): winds exceeding 45 MPH, ooding or immersion in water or other uids,
contact with liquids or substances with a pH less than 6.5 or greater than 8.5, and contact with re, projectiles, lava ow, volcanic
eruptions, or meteors.
Mounting Congurations
Modules installed over a roong system must be mounted over a at, re-resistant roof covering with the appropriate safety rating
for the application. While modules can be mounted at any vertical or horizontal angle, it is recommended that they are installed
at a minimum 10-degree angle to reduce dirt accumulation and soiling.
Water entering the junction box could present a safety hazard, and junction boxes should be oriented on the uppermost position
of the panel. The junction box should never be mounted in a depression. Note the junction box manufacturer rates this product
with an ingress protection rating of IP67 for the box.
Modules may be attached using an adhesive on the panel backside or by using the grommet holes as attachment points. Go
Power! does not recommend a preferred attachment method or make any claim as to the safety of the attachment.
Mount modules away from obstructions such as vents, AC Units, etc.
Module Handling
Always use gloves when handling modules. Modules are sensitive to oils and abrasive surfaces — not doing so may lead to
scratching and soiling. Minimize module contact as much as possible, especially with any abrasive surfaces. Do not place any-
thing on the modules. Do not lift modules by the cables or the junction box under any circumstances. Remove ngerprints from
the panels by washing the panel as described below.
The panels are designed to withstand a 30-degree bend top to bottom (with the junction box placed on the top end) — approximately
8cm of deection. Care must be taken not to bend, ex, or twist panels excessively when handling. Do not place sharp objects
on the panels — this may cause a puncture or damage, resulting in decreased power and creating a potential safety hazard.
Do not use blunt or sharp force with other hardware (junction boxes, cables and connectors). The resulting damage could render
the module unusable.
1. Remove shipping plastic from panel
2. Expose the panel(s) to sunlight and use a voltmeter to test for DC Voltage
3. Locate the solar panels on the RV roof replacing each of the boxes used in the planning step.
4. Locate the Cable Entry Plate / Fridge Vent or Access Point on the roof.
5. Attached the MC4 Positive and Negative Extension Cables to the solar panel(s).
6. Test that the end solar panel cables can reach the GP-CEP / Fridge Vent or Access Point.
7. Use the screws and washers provided in the kit to secure the solar panel to the roof. Or an adhesive sealant can be used
to attach the panels to the roof. Please contact your vehicle manufacturer for specications on an appropriate sealant.
8. Apply sealant under, around and on top of each of the 6 screws to ensure a watertight installation.
Note

INSTALLATION
WARNING: Using an adhesive can create a permanent mounting situation. It is strongly advised that placement
is well thought out and that panel function has been tested before mounting. Go Power! is not responsible
for damage caused by the removal of any solar panels.
WARNING: The Panels must be securely fastened. Failure to do so could cause the panels to lift and separate
from the surface while in transit which could cause signicant damage and/or injury.
Use appropriate sealant as recommended by your RV Dealer for your RV roof.

1. Locate the refrigerator vent on the roof of the RV. Remove
vent cover to gain access to the duct opening.
2. Drill a hole through the side of the vent (5/8” hole).
3. Remove any sharp edges from the hole.
4. Insert a rubber grommet (not included) into the hole.
5.
Insert the MC4 positive and negative extension cables
through the hole and carefully route it to the solar charge
controller. Be certain to leave enough slack to allow cable
routing from module to vent along desired path.
6.
Use cable clamps with the #6 self-tapping screw and/or tie
wraps every few feet along roof and interior route to the
solar charge controller.
7. Ensure all penetrations into the roof or surface are water-
tight. Use an appropriate sealant as recommended by your
RV Dealer to seal holes wherever necessary.
8. Replace vent cover.
4.3 REFRIGERATOR VENT ACCESS
OPTION 2
1. Locate the refrigerator vent on the roof of the RV. Remove
vent cover to gain access to the duct opening.
2.

4.9 BATTERY BANK CONFIGURATIONS
5. MAINTENANCE
5.1 INSPECTION
After installing any Go Power! Solar Kit or any other Go Power! products, all modules, electrical and mechanical components
and connections should be inspected annually by a trained Go Power! or dealer representative or other qualied personnel for
safe electrical and mechanical connections and to ensure modules are corrosion-free and vehicle mounting has not affected
connections.
5.2 CLEANING
Although Go Power! Solar Kits are generally maintenance free, signicant performance gains can be made with clean solar panels
1. Clean the solar panels monthly. Use water and a soft sponge or cloth. A mild non-abrasive cleanser can be used for more
stubborn residue. Rinse well.
2.
Clean solar panels more frequently during drier months, as they may become covered in dust more quickly. A pressure
washer is not recommended.
3.
Visual inspection – check the exterior for cracks, missing or broken hardware or other potential problems. Check all roof
penetrations and replace sealant areas as required
5.3 LONG TERM STORAGE - RV
If your RV will be stored in extremely cold climates you may need to remove your batteries to prevent them from freezing. Please
note if your solar panel(s) are covered by snow they will not produce power and can not be depended upon to keep the batteries
topped up. In mild climate storage you can depend upon your solar system to top up your batteries when they are exposed to
sunlight. Make sure that all parasitic draws are removed from the batteries i.e. Propane detector, clock radio, etc to make sure
the solar panel(s) can keep the batteries topped up even with reduced sun exposure.
