Detailed Product Description wind turbine equipment 1.CE proved+7 patents 2.high efficiency+small size 3.NO MOQ+wholesale price 4.professional factory wind turbine equipment Hummer H3.8-2000w wind turbine generator has the following features : A. With high output efficiency wind alternator generator ,which has four patented technologies . B .The blades are made by the precise ejection model technology ,which is alary and high-efficiency . So Hummer H3.8-2000w wind turbine generator can start up with a low wind speed and use the wind power more efficiently . Compared with the traditional materials ,this new type adopts glass fiber, which can reduce the weight and enhance resistant corrosion . C. Auto-defensive function for over charging ,over discharging ,over speed , over loading ,short circuit etc . D. With the help of hummer wind-solar wind turbine ,2kw wind turbine generator can be connected to solar panel within 1000w . E. Hummer H3.8-2000w wind turbine generator with CE certificate ,easy to install , very suitable for home use .
