Sun Pumps PCA-30M1D - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps SDS series solar pump system. The SDS series pump and PCA-30-
M1D series pump controller are the key components to high quality solar powered pumping systems. Their
stand-alone, pollution free operation makes them an ideal solution for remote homes, irrigation projects,
and wildlife and stock watering without violating the environment.
SunPumps SDS series pumps are diaphragm type, DC powered, submersibles constructed of high quality
stainless steel for the SDS-D and SDS-Q series pumps and Ryton and stainless steel for the SDS-T series
pumps. These pumps were designed specifically for water delivery in remote locations.
The PCA series controllers are microprocessor based solid state DC power converters designed as the
interface between a solar module array and the SDS series 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 SDS 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.
PRECAUTIONS

Safety First – Always understand what you are doing when working with any form of
electricity. Guessing may cause product damage and/or severe personal injury.

Shut down all power when working on the system.

Do not attempt to feed live wires into the PC-series controller. Product damage and/or
personal injury may result.

Do not exceed the voltage rating of the controller.

Do not set the controller to exceed the power rating of the motor.

Do not splash water on the controller when the cover is open.

Mount the controller in a shaded, well vented, vertical position.
2.0 Product Overview
The SunPumps PCA-30-M1D series controllers were designed specifically for SunPumps SDS-series, DC
submersible pumps. When properly installed and configured, the unique features incorporated into this
stand-alone system will automatically control and protect your pump system permitting many years of
dependable, trouble free service.
When used as a solar electric panel direct system the PCA series controllers will provide pump protection
from over-voltage and over-current conditions as well as current boosting in low sunlight conditions.
