E400i Kestrel

Kestrel e400i

Product Description:

Wind‑powered generators that produce electricity, often used in hybrid solar‑wind systems. Kestrel wind turbines are among the best performing and most efficient wind power systems. Kestrel’s strict adherence to quality standards and continuous development of Kestrel technology has resulted in a line of high quality, quiet, powerful, and robust machines in 600, 800, 1000 and 3000 Watts rated power that are both reliable and cost effective.

All Kestrel turbines feature Full Axial Flux Discoid Technology, for high efficiency and increased energy production in lower wind areas. All models use patented pitch control, allowing blades to maintain rated output in excess wind speeds and optimizing overall power production.

Energy may be harvested at any different wind speed exceeding cut-in speed and rated output is maintained through rotor turbulence and pitch control in high winds. Energy output is intrinsically linked to your site’s wind distribution, topology and altitude as well as tower height and the height of trees or structures in the area.

Product highlights:

  • 6.3 mph cut in wind speed, 24.6 mph rated wind speed 3300W, max power rating at 12ms ̄ˡ
  • The e400i is our largest in-stock turbine and optimizes your renewable energy output and performance through efficiency and size
  • The e400i uses 3 aerofoil blades with a 13.12-foot rotor diameter
  • The e400i moderates noise emissions effectively, making it unobtrusive for its size and a reliable method of substantial renewable energy production
  • The e400i advanced direct drive alternator incorporates three main shaft bearings for longevity and increased reliability
  • Appropriate for water pumping, repeater stations, heat production, small wind farm installations, battery charging, grid tie or hybrid systems, the output voltage can range from 48, 200 and 300 Vdc
  • Used around the world to generate dedicated power for housing, community and health centers not connected to the national grid
  • Tower top mass is 331 lbs
  • Used with a tripod tower and a charge-only controller
