3. TOOL AND MATERIALS NEEDED
• Flathead Screwdriver (for wire terminals)
• Philips
Screwdriver (for mounting screws)
If the GP-SB-PWM Controller was purchased with a Go Power! RV Solar Power Kit, then UV resistant wire is included.
Note
For instructions regarding the Go Power! RV Solar Power Kit installation, please refer to the Installation Guide provided
with the Kit.

4. CHOOSING A LOCATION

The GP-SB-PWM is designed to be mounted flush against a wall, out of the way but easily visible.
The GP-SB-PWM 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 controller location is above the refrigerator. 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.

5. CHOOSING A BATTERY

The GP-SB-PWM is suitable for use with lead acid batteries (Sealed, GEL, or AGM type) as well as some lithium iron phosphate (LiFePO4)
batteries that are supplied with a Battery Management System (BMS). If using lithium ion, it must be lithium iron phosphate (LiFePO4)
chemistry with a BMS. Other chemistries with a BMS are compatible if a custom profile is chosen to program specific charging parameters.
Lithium batteries typically have maximum allowed charge currents. These maximums typically decrease in cold temperatures. GP-SB-
PWM does not limit current for these restrictions, and system design of the solar array must account for this.
Be sure to follow all battery manufacturer safety instructions.

6. INSTALLATION INSTRUCTIONS

1. Prepare for mounting. Use the template provided on page 25 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-SB-PWM 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.
3. Select wire type and gauge. If this GP-SB-PWM was purchased as part of a Go Power! Solar Power Kit, appropriate wire type,
gauge, and length is provided. Please continue to Section 7, "Operating Instructions." If the GP-SB-PWM was purchased separately,
follow the instructions included here.
Wire type is recommended to be a stranded copper UV-resistant wire. Wire fatigue and the likelihood of a loose connection are greatly
reduced in stranded wire compared to solid wire. Wire gauge should be able to sustain rated current and minimize voltage drop.
Wire Strip Length
Strip wires to a length of approximately 3/8 in (10 mm, as per strip gauge).
