How to choose solar water pump controller

The solar water pump controller is the brain of the entire irrigation system and must be strictly matched with the pump. ·

-Type matching:

select the corresponding DC controller or AC inverter according to whether the pump is DC or AC.

-Parameter matching:

The rated voltage, power and maximum current of the controller must be greater than or equal to the rated value of the pump. Considering the extension cable, we usually recommend an inverter model one step higher than the rated power of the pump.

-Functional requirements:

must have MPPT (maximum power point tracking) function and perfect protection functions (such as dry turn protection, over voltage, over current, under voltage protection, etc.).
