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 damage protection.

3. When the change 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 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.

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 regulated 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.

1. The combination of microcomputer and full hydraulic system, the minimum speed of 60 to -20 turn, according to the design of the wind field and custom. Rotary support and ultrasonic wind speed wind direction meter, so that the generator has a very good reliability. Using a hydraulic yaw, you can stop at any position, yaw accuracy of less than 0.5 degrees, more accurate. Hydraulic brake, using a disc brakes, you can control any speed or stop and so on. Maximum wind speed tracking function, the wind turbine can set any maximum wind speed in the whole wind speed range, in any case beyond the rated wind speed, to ensure that the wind turbine speed, the maximum output power without downtime, to achieve energy The maximum use.

2. Tower pole: the use of multi-ribbed hot-dip galvanized flange connection, small footprint, three-dimensional sense of stronger, within the ladder design, into the cabin more convenient and more secure, the engine compartment installed workstations and guardrail design, maintenance more convenient.
