1. Low start-up wind speed. The lowest speed is up to 2.5m/s and the starting with breeze can be achieved.
2. High wind energy utilization and large annual power generation.Blades are molded through precision injection with new technology and generator is three phase AC permanent magnetic. It's a clean energy solution for a new generation of wind turbine.
3. High quality. The tail part is made of high quality ABS material and blades are manufactured with nylon fiber. 
4. Light weight, strong stability. It's easy to install, operates with low vibration and the cost can be reduced.
5. High efficiency. The thickness of the coil is a key part of the power generation. The stator windings are enlarge and and quality copper wires are adopted to improve the power generation efficiency of the motor at low speed.
6. High performance. Rotor magnet thickness is increased and double bearings are upgraded. Double ball bearings are used to prevent vertical vibration, improve efficiency, reduce noise and increase yaw stability.
7. Wide Application. Ideal for home use, camping in forest, monitoring use, boat/marine use, wind-solar hybrid streetlight use, etc.

KNOWLEDGE BASE --- The Different Components of a Wind Turbine (Ⅱ)
Many parts of the wind turbine are hidden and invisible inside the nacelle as shown below.
1. Low Speed Shaft
When the wind turbine blades rotate, the low-speed shaft is driven by the rotation of the wind turbine blades and the low-speed shaft transfers kinetic energy to the gearbox.
2. Transmission
The gearbox is a heavy and expensive device that can connect a low-speed shaft to a high-speed shaft. The purpose of the gearbox is to increase the speed to be sufficient for the generator to generate electricity.
3. High-speed Shaft
The high-speed shaft connects the gearbox to the generator and its sole purpose is to drive the generator to generate electricity.
4. Generator
The generator is driven by a high-speed shaft and generates electricity when the high-speed shaft delivers enough kinetic energy.
5. Pitch and Yaw Motors
Some wind turbines are equipped with pitch and yaw motors to help maximize wind turbine efficiency by positioning the blades in the best possible direction and angle.
Usually the pitch motor can be seen near the hub of the rotor, which will help to tilt the blades to provide better aerodynamics. The yaw pitch motor is be located in the tower below the nacelle and will make the nacelle and rotor face the current wind direction.
6. Braking System
The key component of a wind turbine is its braking system, whose function is to prevent the wind turbine blades from rotating too fast and causing damage to the components. When braking is applied, some of the kinetic energy will be converted into heat.
7. Control System
Internal control systems is included in wind turbines, which have multiple uses. It not only has the ability to start the wind turbine when the wind speed is high enough and but also can shut down the wind turbine when the wind speed is too high.
The control system is also a mechanism for calculating the pitch and yaw of the wind turbine effectively based on the wind speed and direction.
