Sun Pumps PCC-BT-M2 - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps PCC-BT series solar pump system. The PCC-BT series pump
controller is a key component to high quality solar powered pumping systems. Their stand-alone, pollution
free and low noise operation makes them an ideal solution for remote homes, irrigation projects, and
wildlife and stock watering without violating the environment.
The PCC-BT series controllers are microprocessor based solid state DC power converters designed as the
interface between a solar module array and a brush type DC pump motor. The purpose of the controller is
to operate the high efficiency, high reliability DC motor and maximize the total daily water output while
providing protection for the pump as well as providing an interface with other related pumping system
equipment and accessories.
Although these PCC-BT series pump controllers are easy to install, please read this manual to
become familiar with the controller features, functions, connection points and various configurations.
For future reference, keep this manual and other relevant product information in a safe place.
