The SunPumps PCC-BT-M2 Solar Pump Controller is a microprocessor based solid state DC power converters designed as the interface between a solar module array and a permanent magnet brush type DC pump motor. The purpose of the controller is to operate the high efficiency brush type DC motor, 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.
The PCC-BT series controllers will boost the current of solar modules in low sunlight conditions while holding the voltage of the solar modules at the maximum power point. This allows a pump to start much earlier in the morning, reach maximum production faster, operate better on cloudy days, and run longer in the evenings.
Sun Pumps PCC-BT series pump controllers have many unique features designed specifically for water pumping. These features include maximum current regulation, maximum voltage regulation, sometimes referred to as “motor speed control”, two remote switch circuits, low power shut-down to save wear on the pump, indicator lights and an LCD screen that displays motor voltage, current, motor speed and power .
PCC-BT-M2 pump controller has a very wide input range to match a variety of systems and can operate with voltage inputs from a 24 volt battery system to a 300 volt open circuit photovoltaic solar array. Output voltage range is from 0 VDC to 195 VDC. The maximum output power is rated at 2730 watts.
The built in LCD screen displays various operating parameters including input voltage and current, motor voltage and current, power, controller board temperature and various system status messages.
The controller is mounted in a high quality, powder coated, cast aluminum enclosure rated for outdoor use.
