The 3kW horizontal wind turbine uses the permanent magnet generator without tail design. The wind turbine could face the wind automatically through the yaw motor and anemometer. This design was usually applied in the 10kw or 20kW wind turbines. It can maximize the annual power output of 3kW wind turbine. This 3kW wind turbine can be used for off grid application with 120V output and grid tie application with 220V output.
