1.0 Installation Overview

1.1 Introduction

A Solar Controller (or Charge Controller / Regulator) is an essential

component of your photovoltaic solar 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) charg

controller rated for a continuous solar current input of 30 amps. The GP-

PWM-30 uses Pulse Width Modulation (PWM) technology and a unique

four stage charging system that includes an 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. The GP-PWM-30 also features Maximum

Power Boost Technology™ for manual bulk charge at

any stage of the

charge cycle.
