4.0 Choosing a Location
The GP-PWM-25 is designed to be mounted flush against a wall, out of the way but
easily visible.
The GP-PWM-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 a RV, the most common regulator location is above the refrigerator. The wire from the
solar array most commonly enters the RV through the fridge vent on the roof. PV
connections should connect directly to the regulator. Positive and negative battery
connections must connect directly from the regulator to the batteries. Use of a positive or
negative distribution bus is allowed between the regulator and battery as long as it is
properly sized, electrically safe and an adequate wire size is maintained.
