Feature:1. With Good Design: The generator adopts a neodymium iron boron dilute permanent magnet synchronous AC generator, which has low noise and long service life. It adopts a tailless blade, 360 automatic adjustment of the windward direction.2. Low Speed Starts: The starting speed of the generator only needs 3.5m/s, and it can automatically adjust the direction to obtain the maximum wind speed.3. Wide Application: With high wind energy utilization and efficiency, this wind turbine can be widely used for home monitoring, RV, boat, pavilion, cabin, ocean, and any other household charging purposes.4. Premium Material: The blade is made of mixed fiber nylon basalt material, waterproof, corrosion resistant, and lightweight. And the bearing temperature range is -43 to 82 .5. Convenient Using: Low in vibration, the wind turbine generator ensures stable power generation as well as convenient installation and maintenance.Specification:Item Type: Wind Turbine GeneratorModel: K1-800WBlade and Outer Cover Material: Mixed fiber nylon basalt material.
