The 902 LCB Controllers boosts the 9300 Submersible pumps performance by up to 30%. The controller optimizes the solar water pumping system by translating the current and voltage from the photovoltaic panels into a combination that is better matched to that needed by the pump. With the optional float switch installed, the controller will automatically stop the pumping when the reservoir is full.
The 902-200 controller has additional features which include a switch selector for 12V operation, a manual on/off switch for easy pump maintenance, high/low water level sensors so the pump will not run when the well water is too low and a waterproof enclosure.
