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 .
