4. variable pitch wind turbine 3kw features
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.

Certification
Workshop, office and stock
1. Wind turbine model selection
It depends your local annual average wind speed, daily/monthly home power consumption.
Low average wind speed place, select larger blades rotor, higher rated working voltage;
Rich wind place select speed limited wind turbine: variable pitch wind turbine, stall out vertical axis wind turbine.
The safety and steady working system is the first choice.
2. Wind turbine tower selection
Now we have guy wire tower, stand alone tower, tilting up tower, hydraulic tower.
Guy wire tower cost is lower, easy to delivery. But the installation area is larger;
Tilting up tower is for 500w-5kw wind turbine. Easy installation, small installation area. But the delivery cost is higher.
Hydraulic tower: It is used for no crane place. Easy installation and put down. The cost is higher.
Stand alone tower for the installation place with crane.
The tower height: Make sure blades rotor is higher than wind turbine surrounding barrier height.
3. Working system selection
On grid system: wind turbine with tower + PWM controller with dump load + grid tie inverter;
Off grid system: wind turbine with tower + PWM charge controller with dump load + battery group + inverter;
Wind solar hybrid on/off grid system: Safety and reliable than only wind or solar system.
Wind turbine water heating system: work in rich wind place. Average wind speed higher than 8m/s.
For more question, pls contact with us directly. We will give you a professional response.
