The SHURflo "LCB - GO" pump controller is a DC power converter designed as an interface between a DC (Solar)-Pump (e.g. SHURflo 9300 series) and a DC power source, like solar panels and wind generators. The main function of this controller is to maximise the daily water output while providing protection for the pump. The solid state controller will protect the pump system and give trouble free service for many years. When used in a solar pumping system, directly connected to the solar power, it will protect the pump from over voltage and over current conditions as well as will provide current boosting in low sunshine (radiation) conditions. Also controls an optional tank float switch [not included].
