50KW wind turbine  technical specfication: 

3. Details: 

Rotor: Rotor efficiency can reach 42%, noise level is less than 65 dB, strict balance adjustment before leave factory.

Generator:Rotor driven directly , low RPM (rotating speed), permanent magnet ,  Overload rate 150%

Use NdFeB35SH Strong Magnetic materials

Excellent bearing (NSK ), long-lasting grease, run 30,000 hours without maintenance

High wind speed halt mode:   When the wind speed exceeds safety value , the variable pitch control system make the blade angle changes, the rotor rotation speed is reduced, the wind blade variable pitch to 90 ° halt; Yaw control at the same time, the rotor axis and the direction of the wind into 90 °, the turbines stop turning. Multiple protection devices at the same time protect the blades rotor, make it safe running.

 Packaging & Shipping

 We started to manufacture wind turbine in 1994. In 2004, there are only 4 small wind turbine manufactures in China. We keep improving and develop in the small wind turbine field. We are not the leading small wind turbine exporter, but we are the leading wind turbine manufacture and designer now. 

 We manufacture 300w-30kw fixed pitch wind turbine;

2kw, 3kw, 5kw, 10kw, 20kw, 30kw, 50kw, 60kw pitch controlled wind turbine;

On grid system/off grid system, wind solar hybrid system; Water heating system;

For more details, pls contact with us via e-mail.

Contact person: Aron wang/engineer. Start sell wind turbine from 2003. Provide wind turbine system design service, technical service

 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. 

Why select us:

We are the wind turbine designer and manufacture. We know our wind turbine advantage and disadvantage in different wind condition.

I have more than 10 years wind turbine sales experience. We provide the right wind turbine and working system to different user according to their different situation and request. 

In 2004, there are 4 small wind turbine manufacture. Now there are so much trading company and manufacture, we know Chinese small wind turbine market well and can provide user more useful advise.
