Key Features
- Low start-up wind speed -
1.8m /s, greatly improves efficiency.
- Low rotating speed, 40 rpm to
generate rated power.
- No noise, <63db at 10m
distance.
- Blades to regulate angles
automatically every 30 seconds, to increase the windward area at low
speed and decrease it at fierce wind.
- Hydraulic tower for easy installation
and maintenance.
- Remote monitoring.
- Optional heating blades.

The angle of the blade can be adjusted by the eccentric rod, controlled by the controller that collects data from anemometer and dogvane.
Under normal wind speed, the blades obtain maximum windward area by just face toward the wind direction. Then the rotation speeds up to achieve the maximum wind utilization.
However, under extreme high wind the blades decrease its windward area to slow down the rotation to protect the device.
