20kw wind turbine, with three-phase generators, blade design of low wind speed, can reduce noise and increase wind energy utilization effectively, it has the mechanical brake system and electronic brake system, and they will effectively protect the 20kw wind turbine in high wind speed, electric voltage, or generator temperature.
20kw wind generators have been used as grid-connected in Italy, UK, France, Greece and many other countries.
