1.0 Installation Overview

1.1 Introduction

A Charge Controller is an essential component of your photovoltaic (PV)
system. The Controller maintains the life of the battery by protecting it
from overcharging. When your battery has reached a 100% state of
charge, the Controller prevents overcharging by limiting the current
flowing into the batteries from your solar array.

The GP-PWM-30 is a 12 volt flush mounted photovoltaic (PV) charge
controller rated for a continuous solar current input of 30 amps. The GP-
PWM-30 uses pulse width modulation technology and a unique four
stage charging system and optional equalize setting to charge and
protect your battery bank. The GP-PWM-30 features an LCD digital
display that shows solar array charge current, system battery voltage
and battery capacity.
