5-30kW Wind Off-grid Controller

Off-grid Controller is technologically the most important component in wind generator systems,which convert Three AC current from wind turbine into DC current then charge the battery bank.The GREEF wind off-grid controller can significantly boosts electricity production through dedicated MPPT technology, and employs advanced technologies such as modular design, electrical isolation, PWM unloading, and host computer control. It is equipped with a large touchscreen and IOT functionality, enabling efficient, safe, and intelligent power generation and operation & maintenance management.

    Product Features

    Power tracking: wind energy MPPT, 98% engagement with actual wind energy output curve, power generation enhancement.
    Customized development of wind energy-specific power absorption circuit:
    1.Modularized power absorption circuit, hot-swappable, easy maintenance.
    2.Input and output electrical isolation, protect the back-end load.
    3.High efficiency at low wind speed, wide input voltage range.
    4.Saturation mode, matching load power output.
    PWM unloading: 
    1.Fan self-powered mode, fast response.
    2.Limit speed and torque to ensure the safe operation of the wind turbine.
    3.Soft unloading adjustment, reduce the burden of fan output.
    Upper computer trusted control: RS485 Modbus RTU, real-time regulation of voltage and current.
    Touch screen: 
    1.Display voltage, current, power, power generation, operation status, etc., with alarm query.
    2.Historical data, alarm information date query.
    3.On-site adjustment of parameters.
    Safety protection: over-voltage, over-current, anti-reverse connection, short circuit protection.
    IOT IOT function: 
    1.Wired network, APP remote view and control.
    2.Remote data export.
