    The e400i (3 kW) Wind Turbine

    Available in 48, 110, 200, and 300 Vdc

    The e400i is the latest development in the Kestrel range. The completely new 120 pole single axial flux direct drive alternator incorporates three main shaft bearings for long service life. The e400i maintains rated output in excess wind speeds using Kestrel patented blade pitch control. The e400i therefore gives an optimum energy harvest with no cut out wind speed. This Kestrel, like the other models optimises low wind and stays in complete control whether loaded or unloaded during excessive wind speeds.

    • e400n Wind Turbine 250 Vdc & 48 Vdc
    • Interface Module 3.5kW 600V
    • e400i Brake
    • Tower 18 meter
