The SunPumps PCA-30M1D Pump Controller is a microprocessor-controlled DC power converter that installs between a DC water pump and its power source and maximizes the pump's performance while also providing protection for both the pump and the power source.
A pump controller is almost essential when the pump is running solar-direct. Because it boosts the current from the solar panel(s) in low-light conditions while holding their voltage at the maximum power point, your pump can start running earlier in the morning and stay running longer into the evening.
The warranty on a SunPumps pump requires the use of this or another SunPumps Pump Controller.
