Sun Pumps MTR BLM-SB-073S-60 - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps SCS series solar pump system. The SCS series
pump and PCA series 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 remote homes, wildlife and stock watering problems
without violating the environment.
SunPumps SCS series pumps are multi-stage centrifugal, brushless, sensorless three
phase DC powered, submersibles constructed of high quality stainless steel. These pumps
were designed specifically for water delivery in remote locations.
The PCA-series controllers are micro-processor-based, solid-state DC power converters
designed as the interface between a solar module array and a brushless, sensorless three
phase DC pump motor. The purpose of the controller is to 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 SCS series pump systems 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.
