Feature:1. Three Phase Motor: The wind generator also has a three phase permanent magnet synchronous motor with high efficiency compact alternator with high performance NdFeB permanent magnet.2. Yaw Adjustment System: Our small wind generators have a yaw adjustment system that automatically reads the wind position and adjusts the rotor position to catch the maximum wind energy.3. Wind Energy Utilization: Small wind generator has high utilization of wind energy, which can make you have a good experience, the longer the blade, the more energy produced, the more power produced.4. Nylon Fiber Blade: The blade is made of nylon fiber, which is waterproof, corrosion proof and lightweight, and the tail fin is designed according to the aerodynamic principle.5. Low Speed Start: Our small wind generator is started at low speed, with low running vibration and high efficiency.Specification:Item Type: Wind GeneratorMaterial: Aluminium Alloy, Nylon FiberRated Power: 300WMaximum Power: 310WStarting Wind Speed: 2.0m/sRated Wind Speed: 13m/sSafe Wind Speed: 50m/sWind Wheel Diameter: Approx. 1.35m/4.4ftNumber of Blades: 3 BladesBlade Material: Nylon fiberGenerator Type: 3 phase AC permanent magnet generatorBraking Method: ElectromagneticWind Direction Adjustment: Automatic windward adjustment.Package List:1 x Wind Generator3 x Blade1 x Flange Base2 x Hex Wrench1 x Controller1 x Rectifier1 x Wind Wheel Hub4 x Large Screws4 x Large Nut8 x Large Washer4 x Washer13 x Small Screw13 x Small Nut
