Detailed Product Description top quality horizontal wind turbine 1.CE proved+7patents 2.high efficiency 3.NO MOQ+wholesale price 4.facotory top quality horizontal wind turbine Though larger in size and weight ,compared with smaller Hummer turbines ,25kw wind generator's efficiency is still kept over 0.8 . And to ensure longer lifespan and better performance ,25kw wind generator adpots S.K.F bearings .All nuts and blots are made of stainless steel . Furthermore ,inside the generator we placed a temperature detector .If the temperature rises over alert level , it will stop working automatically . The main technical datas of hummer 25kw wind turbine generator is as bellowing : Rated power(W) 25000 Maximum output power(W) 37000 Charging voltage (V) DC 240 Blade quantity 3 Rotor blade material GRP Rotor blade diameter(m) 9.0 Start-up wind speed (m/s) 3.0 Rated wind speed (m/s) 11.5 Rated rotating rate (r/min) 180 Wind energy utilizing ratio (Cp) 0.4 Generator output Single-phase frequency conversion AC Rated charging current (A) 104 The maximum charging current (in a short time )(A) 156 Output AC frequency (Hz) 0~320 Generator efficiency >0.87 Free standing tower diameter(mm) 105075016000 (2pcs) Tower height(m) 16 The weight of generator(kg) 496 Battery 12V 150Ah/200Ah 20pcs
