wind turbine off grid system including:

wind turbine 300w/24v or 12v(with 3blades, guy cable tower 6m)

off grid controller 300w/24v

deep cycle battery 12v150ah2pcs

off grid inverter 300w/24v

Features:

1. 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)

2. The design of blades: The blade casted into molding at one time with balance up to 99%.

3. Light generators (only 7.8kg for 300W) make the installation easier and cheaper.

4. 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.

5. Carbon brush casted into molding at one time, it can reduce the contact resistance effectively

   and the lifetime is up to 100000 times. (Patent No.:200920265082.7)
