Installation Overview; Introduction; Specifications - Dometic Go Power GP-PWM-10-SQ User Manual

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-10-SQ is rated for a continuous solar current input of 10 amps, 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.
