2. Warnings
Disconnect all power sources before attempting installation. Electricity can be very
dangerous. Installation should be performed only by a licensed
electrician or qualified personnel.
Battery and wiring safety.
Observe all safety precautions of the battery manufacturer when
handling or working around batteries. When charging, batteries may
produce hydrogen gas, which is highly explosive. Work only 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.
Wiring connections.
Ensure all connections are tight and secure. Loose connections may
generate sparks.
Work safely.
Wear protective eyewear and appropriate clothing during installation.
Use extreme caution when working with electricity and when handling
and working around batteries.
Observe correct polarity
Any contact in reverse polarity, however brief, will cause the
at all times. regulator fuse to blow and may damage the unit.
Do not exceed the GPR-25
The current rating of the solar system is the sum of the short Current
and Voltage circuit currents (Isc) of the solar modules in parallel. The ratings
resulting system Isc current is not to exceed 25 A. The voltage
of the array is the rated open circuit voltage (Voc) of the solar module
and is not to exceed 26 V. If your solar system exceeds these ratings,
contact your dealer for a suitable regulator alternative.
3. Tools and Materials Needed
Drill with 3/32” and 3/8 bits UV Wire (Module(s) to GPR-25)*
Keyhole or Jigsaw Battery Wire (GPR-25 to Battery)*
Phillips Screwdriver Wire Cutters
#8 Flat Washers Wire Strippers
Pencil or Marking Implement Electrical Tape
* If the GPR-25 Charger Controller was purchased with a Go Power! Electric RV Solar Kit then UV resistant
wire is included. For instructions regarding RV Charger Kit installation, please refer to the RV Charger Kit
Installation Guide provided with the Kit.
4. Choosing a Location
The GPR-25 is designed to be mounted flush against a wall, out of the way and easily visible.
The GPR-25 should be:
• mounted as close to the battery as possible.
• mounted on a vertical surface to optimize cooling of the unit.
• indoors, protected from the weather.
In an RV, the most common regulator location is above the refrigerator. The wire from the solar modules
most commonly enters the RV through the fridge vent on the roof. Solar connections should connect
directly to the regulator. Battery connections should connect directly from the regulator to the batteries.
Do not tie the regulator wiring in with the refrigerator wiring or any other DC wiring.
If the flush mount option is not used, ensure that the optional knockout box (Model: GPR-25-KBox) is
securely mounted to the wall before proceeding with the installation of the GPR-25 Regulator.
