Feature:1. After installation, the wind turbine is lantern vertical axes type, which reduces the energy consumption when the wind wheel is facing the wind.2. Using alloy steel and plastic materials, high temperature and corrosion resistance, can be used outdoors for a long time3. The external rotor AC motor is adopted, and the motor structure design effectively reduces the wind resistance torsion during operation.4. The good matching characteristics of the wind wheel and the generator make the entire unit run more reliable.5. Widely used for charging boats, terraces, cabins or mobile homes, and solar and wind power hybrid systems.Specification:Item Type: Wind TurbineMaterial: Alloy steel + plasticRated Wind Speed: 12m/sStarting Wind Speed: 2m/sSafe Wind Speed: 45m/sWind Wheel Diameter: Approx. 0.9meter / 3ftNumber of Blades: 4pcs.Package List:1 x Fastener Pack4 x Blades1 x Wind Turbine1 x User Manual1 x Fixed Piece1 x Wrench1 x ControllerNote:1.
