2. GENERAL INFORMATION
Congratulations on purchasing your Go Power! RV Solar Kit. You have chosen a clean, quiet and sustainable power source.
Go Power! Solar RV Kits allow you to power appliances in your RV, without hooking up to shore power or a noisy generator. Go
Power! Solar RV kits will keep your batteries charged, ensuring you have power when you need it.
This mobile DC power system allows you to enjoy the luxuries that electricity provides, without a campsite hookup. For simple
battery maintenance or full-time live-aboard power, Go Power! RV Solar Power Kits are available in a variety of sizes and can
be installed on RVs, campers, trailers, fth wheels and motor homes. As with any o󰀨-grid power systems, the user is required to
manage electrical loads to ensure continual power availability for essential services. Your location and season (hours of sunlight
available) play a role in how much energy can be harnessed from this kit.
This manual will aid in the process of installing the Go Power! Solar RV Kit. Please read and understand this manual
and all included manuals before installing the Go Power! Solar RV Kit. Review all diagrams included in this guide for
the easiest and safest installation. Please retain this manual for future reference.
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 elec-
tricity, similar to a water tank storing water. This battery power may be used at any time to operate DC powered devices connected
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 GP-PWM-30 Solar Charge Controller included in this kit. See Figure 2-A (below)
and 2-B (on following page) for solar system examples.
WARNING: When connecting multiple panels, they will be connected in PARALLEL. Failure to follow this
connection procedure will cause the system to produce large currents which the protection device, DC fuse,
is not designed to handle.

GENERAL INFORMATION
2.2 CAUTIONS
Disconnect all power sources
before attempting installation
Electricity can be very dangerous. Installation should be performed only by a
licensed electrician or qualied personnel.
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.
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.
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.
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 (pages 20-27) 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, GP-PWM-30 Solar Charge Controller and your Battery Bank as
detailed in the diagrams.
3. For the Elite and Extreme Kits include the Inverter, Charger/Converter and Transfer Switch. For detailed installation of
these system components see the specic manuals included with each item.
4. 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
5. Identify on your RV if you have a Cable Entry Plate (CEP) see Fig 3-A pre-installed by the
RV Manufacturer. The Cable Entry Plate makes the Solar Panel to Solar Charge Controller
installation simpler. (After market purchase of GP-CEP available)
6. 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.
7. Whilst on the roof of your RV identify the refrigerator vent and investigate the vent-fastening
hardware.
3.2 PLACEMENT OF SOLAR PANELS
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. Once you have positioned the boxes
• 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).
• Ensure there is enough room to access the panels and other xed obstacles for future inspection and maintenance.

3.3 LOCATING THE GP-PWM-30 AMP SOLAR CHARGE CONTROLLER
The GP-PWM-30 is included in all Go Power! RV Solar Kits detailed in this manual except for the expansion kits (Retreat-E,
Overlander-E). The GP-PWM-30 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-30
Solar Charge Controller.
1. Plan where the GP-PWM-30 solar charge controller will mount, see Figure 3-B.
• The GP-PWM-30 is designed to be mounted vertically in an indoor location inside a weatherproof enclosure.
• Ideally the GP-PWM-30 should be located so it can be easily seen for monitoring system operation. Locate at
eye level (the backlit LED a󰀨ects viewing angle)
• The location will need access to the cable ends from the solar panels and the battery compartment.
Note
WARNING: Failure to secure the GP-PWM-30 could cause it to become dislodged while the RV is in transit and
cause severe damage to the unit and/or the RV.
FIGURE 3-B

gpelectric.com | [page 13]
4. INSTALLATION
4.1 MOUNTING FEET
1. Assemble 4 mounting feet onto each of the solar panels frame using the 1/4” bolts and nuts. This assembly is easily com-
pleted on the ground before the panels are brought up to the RV roof. (See Figure 4-A)
WARNING:
• The mounting feet must be installed on the 4 outer holes in the panel frame.
• All 4 mounting feet must be used on a solar panel.
• The mounting surface must be at least 1/2” thick and strong enough to support the solar panel mounting hardware.
2. Tighten the nuts securely using a 7/16” wrench.

FIGURE 4-A: SOLAR PANEL INSTALLATION DETAILS
4.2 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.
A solar system assembled from photo-voltaic panels can produce high currents which constitute an increased hazard.
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.
1. Locate the solar panels on the RV roof replacing each the boxes used in the planning step.
2. Locate the Cable Entry Plate / Fridge Vent Access Point on the RV roof.
3. Attached the MC4 Positive and Negative Extension Cables to the solar panel (s).
4. Test that the end solar panel cables can reach the CEP / Fridge Vent Access Point.
5. Use the screws provided in the kit to secure the 4 solar panel mounting feet to the RV.
6. Apply sealant under and around each of the 4 mounting feet to ensure a watertight installation.
WARNING: All 4 mounting feet must be securely fastened to the RV roof. Failure to do so could cause the panels to lift
and separate from the RV 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.
Note

4.3 REFRIGERATOR VENT ACCESS
OPTION 1
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 GP-PWM-30
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 RV roof and interior route to the
GP-PWM-30 Solar Charge Controller.
7. Ensure all penetrations into the RV roof are watertight. Use
an appropriate sealant as recommended by your RV Dealer
to seal holes wherever necessary.
8. Replace vent cover.
4.4 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. Thread MC4 Positive and Negative Extension Cables care -
fully through the screen and into opening.
3. Enlarge screen grid hole if necessary.
4. Remove any sharp edges from the hole.
5. Avoid strapping the power cable to existing wire between
the module and the battery.
Allowing a few inches of space between the power
cable and existing wire will lessen the chance of
voltage loss through thermal conduction.
6. Use cable clamps with the # 6 self-tapping screw and/or
tie wraps every few feet along RV roof and interior route to
the GP-PWM-30 Solar Charge Controller.
7. Ensure all penetrations into the RV roof are watertight. Use
an appropriate sealant as recommended by your RV Dealer
to seal holes wherever necessary.
8. Replace vent cover.
4.5 CABLE ENTRY PLATE - OPTION 3
1. Remove the rubber sealing caps from the ends of the MC4
connectors in the CEP.
2. Plug the Positive and Negative MC4 Connectors from the

4.6 INSTALLING THE GP-PWM-30 SOLAR CHARGE CONTROLLER
Ensure the Solar Panels are covered. 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.
1. Use the template included in the GP-PWM-30 Manual to mark the four mounting holes and the “cutting line for ush mounting”.
2. Drill the mounting holes
3. Use a keyhole or jig saw to cut along the rectangular outline previously marked
4. Cut the MC4 extension cables to length, allow some excess for strain relief/exibility
5. Use the leftover cable to connect the controller to the batteries ensuring the 30A Fuse is installed as per 4.7. If extra battery
cable is required to connect to the battery bank, Go Power! recommends using an equivalent cable to that supplied with the
kits: 10 Gauge Wire rated to – UL/cUL/USE2.
6. Mount the controller to the wall using the four wood screws provided.
7. Ensure the back of the controller is protected from damage by any object

1. Locate the positive battery cable from the PWM 30.
2. Plan where you can safely and easily access the fuse holder
& fuse.
3. Cut the battery positive cable from the PWM 30 to the planned
lengths.
4. Strip the fuse holder cable and positive cable from PWM 30
as shown in Fig 4-F.
5. Thread the red heat-shrink onto the fuse holder cable
6. Insert the fuse holder and PWM 30 stripped cable ends into
the butt splice as shown in Fig 4-G.
7. Crimp the butt splice fully - test the connection by gently
pulling on both cables.
8. Thread the heat-shrink over the butt splice as shown in Fig
4-H.
9. Use the heat gun to shrink the heat shrink over the butt splice
as shown in Fig 4-I.
10. Repeat the process for the other fuse holder cable & battery
bank connection.
11. Do not install the 30A Fuse at this stage.

4.8 CONNECT THE GP-PWM-30 TO BATTERY BANK
It is recommended to connect directly to the battery whenever possible. You can also connect to the converter/charger where
the battery positive and negative wires connect to the converter/charger
1. Clean all corrosion from the battery terminals before proceeding
2. Crimp ring terminals onto the positive and negative cables to be attached to the battery
3. Check the ring terminal crimp connection by gently pulling on the cable and ring terminal
4. Attach the Negative (Black) ring terminal to the battery bank and tighten according to the battery manufacturers specication
5. Attach the Positive (Red) ring terminal to the battery bank and tighten according to the battery manufacturers specication
6. Check all electrical connections
7. Apply a protective coating to the battery terminals
4.9 INITIAL CONNECTION AND OPERATING
1. Check all electrical connections and ensure all cables are securely fastened
2. Install the 30A Fuse into the fuse holder, ensure the fuse holder is securely fastened
3. Remove the opaque material from the solar panels
4. Follow the PWM 30 User Manual and operating steps

5. MAINTENANCE
5.1 INSPECTION
After installing any Go Power Solar RV Kit or any other Go Power products it is prudent to complete a periodic check of all elec-
trical and mechanical connections to ensure no connections have become loose or dislodged through transit vibrations. These
checks should be carried out at least once after the initial kit installation and the rst prolonged RV transit. For safety reasons
periodically check the solar panel rooftop connections and any battery connections for corrosion and possible failure points.
5.2 CLEANING
Although Go Power Solar RV 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 RV STORAGE
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.
