1.0 Installation Overview
1.1 Introduction
A Charge Regulator is an essential component of your photovoltaic system. The Regulator maintains the
life of the battery by protecting it from overcharging. When your battery has reached a 100% state of
charge, the Regulator prevents overcharging by limiting the current flowing into the batteries.
The GPR-25 is a 12 volt flush mounted photovoltaic charge regulator rated for a maximum current of 25
amps. The GPR-25 features an LCD digital display that shows solar array charge current and system
battery voltage. An LED bar graph shows the battery state of charge.
