e400nb (3.5kW) Wind Turbine with Mechanical Brake

The Kestrel e400nb micro wind turbine is fitted with a mechanical band brake that will stop the turbine safely in severe wind conditions. The brake is activated by a simple manual operation at the base of the tower.

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 e400nb is rated at 3.5kW and, being a high-quality machine, has a mass of 250kg with a blade rotor diameter of 4m. Note: The same wind turbine is available in selected countries without the mechanical brake and is designated the e400n.

Certifications:

The Kestrel e400nb 3.5kW small wind turbine is the first of its type to be MCS (Microgeneration Certification Scheme) certified. Therefore, it is UK Government approved and qualifies for the Feed-In Tariff (FIT). It is also certified with the North American Small Wind Certification Council (SWCC). The incentives to install wind energy in the US include tax credits, interest-free loans, and FIT schemes.
