【Premium Material】Wind generator blades are made of Nylon fiber which is waterproof, corrosion-resistant, and lightweight, along with die-casting aluminum alloy fuselage and stainless steel fittings, making this product sturdy and strong. 【Powerful Performance】The unique magnetic circuit design makes the starting torque very small, ensuring wind turbine generator breeze starting ability. Moreover, the 3-phase AC permanent magnet generator help this machine reach the maximum wind speed of 50m/s. 【Low Vibration&Noise】The thickened ball bearing makes it more stable with low vibration.And the 40db low noise provides a more comfortable environment. 【Rotating Aluminum Alloy Body】Wind turbine with yaw adjustment system, the wind direction position is automatically read and the rotor position is adjusted to capture the maximum wind energy. The tail fin is designed according to the aerodynamic principle. 【8nylon Fiber Blades】The 8‑blade wind turbines adopts a humanized design, which is easy to install, maintain and repair. Used for boats, terraces, cabins or mobile houses charging, etc. Combined with optimized design of aerodynamic shape and structure, can increase annual power generation.
