  • Page 10: Grid-Tied Wind Power Inverter Description

    1-4 Grid-tied Wind Power Inverter Description This product is a wind energy utility grid-tied system. Single-phase grid-tied wind power inverter is different from traditional stand- alone type wind energy inverter; it does not need additional expensive and large space required energy storage battery, hence free from considerable battery maintenance expense.
  • Page 11 B. High-Wind Protection (Furl Protection) In case of high wind speeds, the High-Wind Protection Function system will protect the wind turbine automatically. When furled, the rotor will turn away from the wind direction, the rotor speed will reduce, and the power output of the turbine will be significantly reduced. High-Wind Protection Function is an easy method to provide high wind speed protection.
