Kestrel E220

Kestrel E220

The Kestrel e220 employs a unique variable-pitch 2.2 meter (7.2’) fiberglass rotor driving a discoid axial flux alternator, which allows for high low wind efficiency and full rated power output in all winds at or above 12 M/S (25.76 MPH) without energy-robbing yawing or electronic shutdown. Because of its large swept area and high efficiency, the e220 is a great choice for low wind sites, yet is equally at home in high winds. Suggested uses include battery charging, direct water pumping, resistance heating and utility inter-tie (with an approved inverter).
