FD3.8-2.5kw Variable pitch wind turbine IEC61400-2 home use mini Wind power generator
Advantages :
- Blades rotor: Blades rotor efficiency can reach 0.42. Noise level is less than 65db, and balance adjustment has been carried out strictly before leaving factory.
- Generator: Blades rotor drives directly. Lower rotation speed, PMG synchronous generator, over load capacity is 150%.
- Pitch controlled wind turbine: Adopt stable pitch controlled system, can be used in variable environments
- Low failure rate
- Speed regulates Performance: The precision of pitch controlled system is 10 r/min, and never over speed at gale. Low Start up Wind Speed: According to different wind conditions, adjust the blade initial angle to make wind turbine start up at low wind speed.
- The start-up wind speed is ≤3m/s.
- Manual brake: Reliable braking system, easy to operate, can stop wind turbine at any time.
- Automatically undo cable: slip rings undo the cable automatically. Ensure the cable has not twist. Double carbon brushes structure make sure power transfer without failure.
- Well-adapted Wind turbine: The operation wind speed is 3-30m/s.

Our Certificates and wind turbine test report :
Our Factory :
1. Wind tubine model selection
Pls check your local place average wind speed,then we will provide recommend model for you.
Low average wind speed place can select larger bldes rotor, higher tower, higher voltage wind turbine;
Rich wind place can select normal blades rotor diameter. Speed limited system.
2. Working system
If you local place has grid power, you can select:
off grid system +grid power hybrid system; Wind solar off grid sysem + grid power hybid system;
On grid system;
If there is no grid power, you can select wnd tubine off grid system + backup power hybid ystem;
Wind solar off grid system + backup power hybrid system.
3. Tower selection:
The blades rotor bottom tip should be higher than max surrounding barrier.
