Kestrel e220 (800W)

Available in 12, 24, 48, 110 and 200 Vdc PictureE220-800W

  • Off-Grid Electricty Supply
  • Power water pumps
  • Charge batteries
  • Supply the national grid
  • Boost hybrid systems for increased energy efficiency

The e220 is a distinctive 3 blade turbine that has a low start up torque, increasing its efficiency. The axial flux permanent magnet brushless alternator is driven by the optimised three blade rotor, with better heat management. The e220 maintains rated output in excess wind speeds, optimising the potential power output and energy yield. The e220 is used predominantly on farms and rural installations for power where the grid does not service.
