FOC specializes in advanced PMSM solar pump controllers designed for efficient water pumping systems using Field Oriented Control technology.
FOC is a brand designation representing high-performance solar pump controllers, primarily manufactured by Hober Technology (Hobertek). These controllers utilize Field Oriented Control (FOC) technology to drive Brushless DC (BLDC) motors and Permanent Magnet Synchronous Motors (PMSM) with high efficiency and low noise.
Designed for agricultural irrigation and industrial water supply, FOC controllers feature automatic MPPT (Maximum Power Point Tracking) to optimize solar panel output. The products are engineered to withstand diverse environmental conditions, offering protection against over-voltage, phase loss, and dry running. Based in Foshan City, China, the brand emphasizes robust durability and intelligent control for off-grid water solutions.

The flashing Error LED and beep alarm indicate specific faults. For example, 1 flash typically means input over-voltage, 10 flashes indicate over-temperature, and 13 flashes indicate the borehole water is empty. Consult the user manual for the full code list.
The device must be installed vertically to ensure convection cooling. It should be placed at a height of over 1.1m in a dry, dust-free environment, away from direct sunlight, corrosive gas, or rain.
The manufacturer typically provides an 18-month quality warranty. Warranty claims usually require photos or videos of the failure and the serial ID. Note that damage from improper installation or water ingress is generally not covered.
Yes, the controller is compatible with battery inputs (e.g., 24V, 36V, 48V, 96V, 110V modes) in addition to solar panel input.
