Smaller scale wind power turbines for residential scale use are available. They are usually approximately 7 to 25 feet (2.1–7.6 m) in diameter and produce electricity at a rate of 300 to 10,000 watts at their tested wind speed. Some units have been designed to be very lightweight in their construction, e.g. 16 kilograms (35 lb), allowing sensitivity to minor wind movements and a rapid response to wind gusts typically found in urban settings and easy mounting much like a television antenna. It is claimed, and a few are certified, as being inaudible even a few feet (about a metre) under the turbine.

The majority of residential small wind power turbines are traditional horizontal axis wind turbines,but vertical axis wind turbines are a growing type of wind turbine in the small-wind market. The generators for residential small wind turbines usually are three-phase alternating current generators and the trend is to use the induction type. They are options for direct current output for battery charging and power inverters to convert the power back to AC but at constant frequency for grid connectivity. Some models utilize single-phase generators.

MINI Residential Small Wind Power Turbine Characteristics:

1.Low start-up wind speed
Low wind speed series wind turbines generate more than 60% effective power than the same rotor diameter wind turbine annually.

2.High-efficient Generator
Three-phase permanent magnet synchronous wind turbine,more than 10% of the efficiency of ultra-GB,starting resistance,only be 1/3 of the GB limit,motor insulation rating class H insulation.

3.Unique patent design
Inserted design of the blade and hub, it will prevent the blades fly away when turns in high wind speed. Also the pin at the shaft, it is the double protection of the wind turbine.

4.Innovative Noise Reduction Technology
Start and product electricity at the 1.5m/s,noise only at 40db at 13m/s/.

5.Perfect Wind Wheel System
The wind turbine wheel are made of a low temperature resistance,aging high strength compound material,can cope with a variety of complex wind conditions,charge wind energy into electrical energy efficiently and sustainably.

6.Unique Design Of The Rudder
Wind turbine rudders are ale to respond to the wind speed and wind direction flexibly,enhancing the efficiency of power generation.
