***1.5 ~ 2m/s start up wind speed with low torque starting technique applied.
**The Reason: Generator make up of 27 skewed slots stator and 12 poles rotor which reduced the cogging torque. (Patent No.:201020259729.8)
**The design of blades: The blade cast into molding at one time with balance up to 99%.
Light generators (only 7.5kg for 200W/300W, **8.5kg for 400W) make the installation easier and cheaper.
**The turbine tail and yawing part (nylon and fiberglass materials with high strength) processed with reinforced ribs, enhance the reliability and can withstand the typhoon.
**Carbon brush cast into molding at one time, it can reduce the contact resistance effectively and the lifetime is up to 100000 times. (Patent No.:200920265082.7)
