Sun Pumps SCP 48-18-48Y BC - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps SCP series solar pool pump system. The SCP series pump and PCA or PCC
series Sensorless Brushless DC - pump controller are the key components to high quality solar powered pumping
systems. Their stand-alone, pollution free and low noise operation makes them an ideal solution for swimming
pool filtration, spas, hot tubs water falls, pond water circulation and flood irrigation.
SunPumps SCP series pumps are single-stage centrifugal type with sensorless brushless DC motors designed
specifically for pool water filtration but can be used for water falls or low head irrigation systems as long as it is
part of a permanent installation. Do not use with storable pools.
The PC series brushless DC controllers are microprocessor based solid state DC power converters designed as the
interface between a solar module array and a sensorless brushless 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.
Although these PC series pump controllers are easy to install, please read this manual to become familiar
with the controller features, functions, connection points and various configurations. Save this manual and
other relevant product information in a safe place for future reference.
