Detailed Product Description wind energy turbine 1.CE proved+7 patents 2.high efficiency+small size 3.NO MOQ+wholesale price 4.professtional factory wind energy turbine Model: H4.6-3kw H4.6-3kw wind energy turbine adopts permanent magnetic material,Cuprum alloy and Aerometal to approach the aim of small size,light weight and high efficiency. Hummer wind energy turbine is designed with seven technical patents,one of which is the technology of starting-up in breeze.Due to the technology,Hummer wind energy turbine has lower start-up wind speed than ordinary wind turbine. Hummer wind energy turbine has off-grid and on-grid model which is based on friendly design and advanced control system.So Hummer wind turbine has the feature of stable operation. Hummer wind energy turbines have been awarded CE,and exported to more than 100 countries and regions. Hummer H4.6-3kw wind energy turbine is well used in: Housing, office and farm Telecommunications Station TV Transfer Station Monitoring Station (military, hydrology, observatory) Water-pumping Station shipping use Main technical data Rated power (W) 3000 Maximum output power (W) 4500 Charging voltage (V) DC 180 Blade quantity 3 Rotor blade material GRP Rotor blade diameter (ft.) 16 (4.8m) Start-up wind speed (mph) 6 (2.5m/s) Rated wind speed (mph) 22 (10.0m/s) Rated rotating rate (r/min) 265 Wind energy utilizing ratio (Cp) 0.4 Generator output Frequency conversion AC Rated charging current (A) 16.7 The maximum charging current (in a short time)(A) 28 Output AC frequency (Hz) 0~360 Generator efficiency >0.8 Wireless tower diameter (in.)
