20KW Low Speed 220v 380v Alloy Blade Vertical Wind Turbine ON Grid System
Using vertical blades and triangular double-fulcrum, The problems of blade lose/broken or leaf flying-out have been well solved. Horizontal rotation and aircraft wing design reduce the noise to an unperceivable level in natural environment. Horizontal rotation and triangular double fulcrum design make it only bear a small wind pressure even in strong wind. Smaller rotation radius than other types of wind turbines, space is saved while efficiency improved. The power generation increasing gently, it could produce 10% to 30% more power than other types of wind turbines. Effective wind speed range. Special control principle expended the wind speed to 2.5 25m/s, utilizes wind resource effectively and obtains a higher power generation. The blade itself has speed protection, and can configure manual mechanical and electronic brake meantime. Without gear box and steering mechanism, the wind turbine only needs regula check every 6 months. Top net weight: 420kg. Wind turbine diameter: 3.5 m. Rated wind speed: 12m/s. Start wind speed: 2.2m/s. Survival wind speed: 40m/s. Generator: 3-phase permanent magnet synchronous generator. Lifespan: More than 20 years. Warehouse: HRB or for your order. Blade Material: Aluminum alloy. Shell Material: Aluminum Alloy. Permanent Magnet Material: Rare Earth NdFeB. Working temperature: -40 to 80. 1 x Wind Turbine Generator. 3 x alloy blades. 1 User Manual 1 15m tower 1 on grid inverter 1 dump load. PLEASE NOTE: The mast is not included as the mast height needs to be 4-6 meters. We therefore recommend that you prepare the mast yourself. We can provide flange size for reference. The blade material is synthetically injection molded with high-strength FRP material. At the same time, the fashionable spiral blade is also designed with aerodynamics to make the rotor run smoothly, reliably and quietly. Coreless PMG provides lower start torque/wind speed and longer service life. Design service life 1015 years. No higher than 300RPM, regardless of the wind speed. Designed with three-phase AC PMG, it boasts low torque, high-power tracking intelligent microprocessor that can effectively regulating the current and voltage. It obviously increases wind energy utilization and annual power generation. With dual bearings, the fan movement is more stable. Low vibration and low noise. In addition, with its compact shape, it has the lowest starting wind speed and a larger windward area, enabling it to generate electricity at lower wind speeds. All things you need for installation are included. You can also get extra installation tool (two wrenches). Humanized and convenient flange design, easy to install and maintain. It is ideally suited for boats, gazebos, cabins or mobile homes, as well as for green windmills, home, corporate and industrial energy supplem.
