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.
