[Low Noise] The aluminum alloy case of the wind turbine is light and pretty, low vibration. [High Efficiency] Optimized design of aerodynamic contour and structure enable the generator to start-up in low wind speed, and improve the utilization of wind energy, so that the annual power generation can be increased. [Safe and reliable] Adopts mechanical and electromagnetic dual over-speed control design, improve safety and reliability in operation. [Durable and Sturdy] The shell is covered by high quality primer and enamel, protecting it from UV, mould, salt spray and damp air. The wind turbine can be used for 15 years without any maintenance if it is correctly applied; 3-year warranty is provided. Can work at -40° C ~ 80°C. [Automated] Auto wind direction adjustment. By operating with the controller, it can monitor the data constantly during operation and give fault alarm in time.
