Product Description:
Off-grid Controller plays a critical role in wind generator systems as it is technologically the most essential component. It is responsible for converting Three AC current produced by the wind turbine into DC current, which is then used to charge the battery bank. The GREEF wind off-grid controller stands out by significantly enhancing electricity production through its dedicated MPPT technology.
Furthermore, the controller incorporates cutting-edge features like modular design, electrical isolation, PWM unloading, and host computer control. With a large touchscreen and Internet of Things (IoT) functionality, the GREEF wind off-grid controller facilitates efficient, safe, and intelligent power generation. It also supports operation and maintenance management, making it a comprehensive solution for wind energy systems.
