20KW wind generator set

A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility.Rotor Diameter (m) 10.0 Material and number of the blades Reinforced fiber glass*3 Rated power/maximum power 20/31kw Rated wind speed (m/s) 11 Startup wind speed (m/s) 2.5 Working wind speed (m/s) 3 25 Survived wind speed(m/s) 45 Rated rotate speed(r/min) 200 Working voltage DC240V/360V/480V Generator style Three phase, permanent magnet Charging method Constant voltage current saving Speed regulation method Yaw+ Auto brake Weight1496kgTower height (m) 18 Suggested battery capacity12V/200AH Deep cycle battery 80pcsLife time 15years As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system.Small wind systems for remote applications operate somewhat differently, and it needs batteries.
