Detailed Product Description wind power generator 1.CE proved+7patents 2.high efficiency+small size 3.NO MOQ+wholesale price 4.professional factory wind power generator Hummer 20kw wind power generator is able to automatically seek wind direction and constantly monitor:generator working status ,rotation speed ,generator temperature , wind speed and direction etc . All data will be transmitted to control center located in inverter . When abnormal situations take place ,our control center will instruct wind turbine to deflect from wind .After problem is released ,wind turbine will turn to face the wind direction again and resume generation . The main technical datas of hummer 20kw wind power generator is as bellowing : Rated power(W) 20000 Maximum output power(W) 28000 Charging voltage (V) DC 240 Blade quantity 3 Rotor blade material GRP Rotor blade diameter (ft.) 30 (9.0m) Start-up wind speed (mph) 7 (3.0m/s) Rated wind speed (mph) 26 (11.5m/s) Rated rotating rate (r/min) 180 Wind energy utilizing ratio (Cp) 0.40 Generator output Frequency conversion AC Rated charging current (A) 83.3 The maximum charging current (in a short time) (A) 120 Output AC frequency (Hz) 0~320 Generator efficiency >0.87 Free standing tower diameter (in.)
