GENERAL
The Trailer Liftgate System is designed to increase the life and performance
of your liftgate batteries by providing a clean, quiet and sustainable power
source. This manual will aid in the process of installing the Go Power! Solar
Kit. Please read and understand this manual before installation. Review all
figures included in this guide for the easiest and safest
installation.
DISCLAIMERS
IMPORTANT: Please follow installation and wiring instructions exactly as
outlined to ensure safety. We recommend installation by a technician or
professional electrician to ensure adherence to relevant electrical codes. We
have made every reasonable effort to ensure the accuracy of the instructions
in this manual, but Go Power! does not guarantee that the information is error
free, nor do we make any other representation, warranty or guarantee that the
information is accurate, correct, reliable or current. For additional
information please see www.gpelectric.com .
DISCLAIMER: This kit has been engineered for use in a mobile application.
Any variance by the end-user is solely of their own discretion. Go Power!
Dometic assumes no responsibility for improper installation in accordance with
any laws and regulations governing: cottage, residential or commercial
applications. Go Power! disclaims liability for any direct, indirect or
incidental damages caused by, or in case of, installation not performed
following the instructions and cautions in this manual. Go Power! will refuse
requests for exchanges or returns, resulting from the purchase and
installation of items which do not comply with local codes. To avoid such
concerns Go Power! recommends installation by a professional electrician or
technician. Examples that are shown within this manual are for illustrative
purposes only.
WARNING: The solar panels must be securely fastened only to a rigid
surface on your truck/trailer roof. Failure to do so could cause the panels to
lift, flex and separate from the roof while in transit which could cause
significant damage, fire and/or injury.
CAUTIONS
**** Disconnect all power
sources before attempting
installationSolar panel safety| Electricity can be very dangerous.
Installation should be performed only by a licensed electrician or qualified
personnel.
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 series, voltages are
additive. Consequently, a system assembled from photovoltaic panels can p
roduce high voltages, 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 flame, cigarettes or sparks. Shield
skin and eyes from battery acid.
Ensure all connections are tight and secure. Loose connections may generate
sparks
and heat. Be sure to check 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. Use properly insulated tools only.
Observe coned polarity at
all times| Reverse polarity of the battery terminals or solar terminals may
damage the controller.
PLANNING
- Turn off any accessories or equipment, including connections) to the truck/tractor.
- Disconnect all negative battery connections from the liftgate batteries.
- Determine the location for solar panel installation. Usually the panels are mounted on the roof above the battery location to keep the wire run as short as possible.
- Plan out wire routing before permanently mounting the solar panel and any wiring. In many installations it is better to mock up the whole installation before adhering the panels.
**NOTE*** Leave a gap of 1” between panels to allow for expansion and contraction and to ensure solar cells are not covered by 4Evaseal Tape.
- Ensure that all wiring is protected from rough or sharp edges.
¢ Must use isopropyl alcohal or any other degreaser.
Must ensure the solar panel location is completely clean. This surface must be dry and above 45°F/8°C before adhering the panel to the trailer roof.
SOLAR PANELS
- Remove the thin protective layer from the top surface of the panel.
- Peel back a small portion (~5″) of the nonstick layer of the adhesive backing tape (Figure 1) on the top or bottom of the solar module. Place the side of the panel with the exposed adhesive in the desired panel location.
- Now that your panel is in position, remove the remainder of the nonstick layer. Press down on the panel. Apply even pressure to the entire panel to ensure it is properly adhered to the trailer roof.
- Apply 4Evaseal Tape over the perimeter of the panel. Ensure solar cells are not covered. If using tape, ensure good adhesion around entire perimeter of solar panel. (Figure 2)
- If installing multiple panels, repeat steps 1-4 for each panel. Locate multiple panels adjacent to each other. A maximum of three 110W panels should be connected in series when using the Go Power! 20-amp MPPT controller.
- If installing multiple panels, use the SC cables that are connected to the solar panel junction box. Connect the positive SC connector to the negative connect or of the adjacent panel. This will connect the panels in series and compound the output voltage of the panel. (Figure 3)
- Attach the SC solar extension hamess to the unused positive and negative SC connectors on the panel(s). Note, ensure the Positive connection from the panel(s) is made with the red wire on the harness and the negative with the black wire. If the wrong side of the solar hamess is connected, the system will still work, but the wire colors will be reversed.
- Secure all harnessing to roof using 4Evaseal Tape. (Figures 3-4)
- Route the harness down the trailer to the liftgate batteries. If available, use an existing conduit or channel. (Figure 4)
- Cover solar panel{s) with opaque material or the boxes they came in to halt the production of electricity while working with solar controller wiring in Part 3.

SOLAR CHARGE CONTROLLER
- Find a location close to the battery where the solar controller can be mounted. Make sure this location is close enough to the batteries to use the provided battery harness.
- Use mechanical fasteners to secure the charge controller near the batteries. (Figure 5)
- Connect the battery harness to the charge controller using the Delphi connectors. Route the solar controllers positive and negative connections to the positive and negative terminals on the battery. Attach the black wire to the negative terminal on the battery and the red/white wire to the positive terminal on the battery. (Figure 6)
- If installing more than one battery, connect batteries together as shown to charge and discharge batteries evenly. (Figure 7)
- Reconnect negative battery connections disconnected in Part 1.
- Attachthe SC solar extension harness to the solar controller using the SC connectors. (Figure 5)
-
To ensure the solar panels are charging the batteries, you will require a clamp-on ammeter. Make sure the solar panel(s) are in the sunlight. Clip the clamp-on ammeter around the positive solar connection between the solar controller and the liftgate batteries. Activate the liftgate for one cycle. You will see current on the ammeter as the power flows from the solar controller to the battery. The charge controller can take up to one minute to start charging, so there may be a delay before current flow is registered on the ammeter.

SOLAR PANEL MAINTENANCE
Although Go Power! Solar Kits are generally maintenance free, performance gains can be made with clean solar panels.
- 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.
- Clean solar panels more frequently during drier months, as they may become covered in dust more quickly. A pressure washer is not recommended.
- 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.
