The Features of our wind generator as follow:

1.Low speed permanent magnet generator

2.Low starting torque,High generating efficiency

3.Glassfibre high efficiency blades

4.Neodymium magnets and bearing with high performance

5.Yaw motor system

6.Designed for minimal maintenance and easy install

7.Aerodynamic brake & manul brake

   

Micro-computer intelligence controller

1.If the system meet problem ,and the wind turbine is running ,it can prevent the wind turbine race rotation .

2.have the auto-protection function of the batteries Reverse protection, anti-disconnect battery protection, battery damage protection.

3.when the charge current is high in strong wind,controller can load the wind turbine automatically. And charging the battery with low current.

4.The wind turbine brake automatically when the battery bank voltage get to rated voltage 125%; and stop charging the batteries.

5.the wind turbine get back charging the batteries when the the battery bank voltage get to rated voltage 108%

6.Controller with a manual emergency brake switch, users can use depending on the circumstances. Using this switch, the wind turbine will be brake..

 

 

Pure sine wave inverter

1.  Pure sine wave output can drive any household appliances.

2.  Use integrated circuit, less wire connection.

3.  Adopting micro-processor technology, improving system integration.

4.  Excellent protection includes over voltage shutdown, under voltage shutdown, over load  protection, short circuit protection, over thermal protection, etc.

5.  Be able to work in wind power or wind&solar hybrid system

6.  With high efficiency transformer instead of high frequency e-circuit design

7.   Automatic regulate voltage,

8.   LCD display operation status,

9.   High running stability and reliability

10. True sine wave form power output

11. High efficient transformer isolation

12. Buzzer alarm while over-loading/voltage, high-temperature
