Our 3-blade wind turbine generator is an efficient and energy-saving clean energy generation device. It adopts a vertical and aerodynamic design, which can start and generate power output at lower wind speeds. High conversion efficiency, excellent protective performance, and simple installation make this product an ideal choice for both home use and tourism energy supply.  Key Features Long Service Life: Premium ABS and neodymium iron boron are treated with oxidation and paint spraying, which are corrosion-resistant, waterproof, not easy to rust or deform, and have a long service life.  High Conversion Efficiency: Its blades are designed with aerodynamics and it has double bearings to ensure smooth and reliable rotor operation, reduce vibration, and improve wind energy conversion efficiency.  Smooth Operation: It has a low start wind speed (6.56-8.2ft/s). At the same time, the product also has an automatic windward adjustment function, which can work smoothly in different wind directions.  Low Noise: The blades draw inspiration from the design principles of aircraft wings and horizontal plane rotation, which only produces a noise of less than 30dB.  Safe Use: After reaching the maximum speed of 300RPM, this product will automatically stop, which can effectively prevent overload. The vertical design can reduce the wind pressure caused by rotation.  Eco-friendly: This product can convert wind energy into electrical energy.  Good Protection Effect: The IP67 protection level allows the product to be used in rainy or other harsh weather conditions without worrying about the device being affected by the weather.  Details Controller with Wires: It is equipped with black, green, and red wires for easy product wiring. Colorful Fan Blades: Bright-colored blades make the product unique and easily recognizable, enhancing its aesthetic appeal.  Application This product is suitable for use in ships, pavilions, cabins, RVs, windmills, households, businesses, and industrial energy supply.
