3. Tools and Materials Needed
• Flathead Screwdriver (for wire terminals)
• Philips Screwdriver (for mounting screws)
If the GP-PWM-30 Controller was purchased with a Go Power! RV Solar
Power Kit then UV resistant wire is included. For instructions regarding the
Go Power! RV Solar Power Kit installation, please refer to the Installation
Guide provided with the Kit.
Note
4. Choosing a Location
The GP-PWM-30 is designed to be mounted flush against a wall, out of the way but
easily visible.
The GP-PWM-30 should be:
• Mounted as close to the battery 1 as possible
• Mounted on a vertical surface to optimize cooling of the unit
• Indoors, protected from the weather
It is is recommended to install the controller in a location that is easy to view and
access. The wire from the solar array most commonly enters the RV through the
fridge vent on the roof or by using the Go Power! Cable Entry Plate (sold separately)
that allows installers to run wires through any part of the roof. PV connections should
connect directly to the controller. Positive and negative battery connections must connect
directly from the controller to the batteries. Use of a positive or negative distribution bus
is allowed between the controller and battery as long as it is properly sized, electrically
safe and an adequate wire size is maintained.
1. Prepare for mounting.
Use the template provided on
page 23
to mark the four
mounting holes and the cutting line for flush mounting your controller.
2. Complete the installation of the solar modules.
If this GP-PWM-30 was
purchased as part of a Go Power! Solar Power Kit, follow the Installation Guide
provided. Otherwise, follow manufacturer’s instructions for solar module mounting
and wiring.
IMPORTANT:
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 the surface of the panels.
3. Select wire type and gauge.
If this GP-PWM-30 was purchased as part of a
Go Power! Solar Power Kit, appropriate wire type, gauge and length is provided.
