The Kestrel e400n micro wind turbine is rated at 3.5kW.
Electricity produced by the turbine is processed by an electronic inverter and fed into the grid. The electricity supply is preferentially wind power and any shortfall during peak demand is supplied by the grid. The end user's energy bill is therefore reduced by the amount of wind energy harvested.
This wind turbine comes standard with Kestrel’s patented pitch control. The blade pitch angle is adjusted automatically in high wind speeds, thereby ensuring maximum power output while reducing the thrust force on the turbine.
The Kestrel e400n is rated at 3.5kW and, being a high-quality machine, has a mass of 250kg with a blade rotor diameter of 4m. It has an electrical brake, which needs to be switched on manually.
