100kW Wind Power

Small Industrial Sites, Small Communities and Municipalities School Commercial Farms or Remote Village Wind Diesel Power Systems

The 100kW unit is a technological masterpiece with its innovative gearless design best in class reliability and pleasing aesthetics. The turbine is optimized for low wind speeds so you don’t have to live in a wind tunnel to benefit from wind power. Our turbines begin making power at wind speeds as low as 3.5 meters per second (7.8 mph) and can provide clear economic benefits in all kinds of wind regimes .

Permanent Magnet Direct-Drive technology maximizes energy capture and outperforms conventional gearbox designs. A state-of the art power converter design provides smooth, clean power to local grids simplifying grid interconnect and adding to grid stability.
