H4.6-3KW off-gird wind turbine



 


1.Advantage:

A.Advanced SCF supercritical generator technology, generator weight is 1/3-1/5 of traditional ones, make hummer wind turbine lighter,smaller and more efficient;

 

B.Innovative breeze start patent technology;

 

C.Two SKF bearing, stable inner and outer ring, it has higher rated bearings and lower noise as well as long service life;

 

D.Top quality component, hummer generator body wins 4 proprietary intellectual property rights, which be made of high-efficiency magnetic materials, special copper alloy, high-strength stainless steel and aeronautic aluminum alloys, make high generating efficiency.
