Detailed Product Description wind generator equipment 1.CE proved+7patents 2.high efficiency+small size 3.NO MOQ+wholesale price 4.professional factory wind generator equipment Hummer 20kw wind turbine system with ALL-IN-ONE inverter , though it is called inverter , it is much more the name indicates . For the entire wind turbine system ,Hummer ALL-IN-ONE inverter functions as the control center .It constantly processes the environmental data and instructs wind turbine to react accordingly . Meantime ,it will keep moritoring the status of battery (off-gird model) or state grid(grid-tied model ).Through its CPU center ,it will send different orders simultaneously with the change of situation . It is desighed with cutting-edge technology ,highly efficient,compact and automatic.Through HUMMER ALL-IN-ONE inverter ,the entire system is able to run on its own without any manual operation . Hummer 20kw wind turbine system 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 . Application of Model H9.0-20000W It can drive air-condition ( ¡Ü20 horsepower), 6kw water pump or other resistive appliances (¡Ü20KW). Well used in: Housing and factory and farm Telecommunication Station TV Transfer Station Monitoring Station (military, hydrology, observatory) Water-pumping Station shipping Main technical parameter 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.) ?41.3?29.5 (1050750mm) (2 segment) Tower height (ft.) 52 (16m) The weight of generator(lb) 1093 (496kg) Suggested Battery (Ah) 800/1000
