1100W Doyin DYS-120 DC Solar Pump Controller – MPPT Control, Dry-Run Protection, Automatic Operation

Product Overview

The 1100W Doyin DYS-120 DC Solar Pump Controller is designed to manage and protect compatible DC solar water pumps rated up to 1100W. It regulates power supplied from the solar PV array to the pump, helping maintain efficient water pumping as available solar energy changes throughout the day.

Its control system is particularly useful for borehole, irrigation, livestock and remote water-supply installations where direct solar pumping is preferred. Integrated operating protections help safeguard the pump and controller against common abnormal operating conditions, while automatic operation reduces the need for continuous manual control.

Macire supplies the Doyin DYS-120 for correctly matched Doyin solar pumping systems and can provide guidance on pump, controller and solar-panel sizing for Kenyan installations.
