qr5 4200 7400 Direct-drive permanent magnet synchronous generator integrated into the base of the rotor Grid Connection Peak power tracking constantly optimises turbine output for all sites and windspeeds Overspeed braking above 14m/s wind speed, auto shutdown in high wind speeds (above 16m/s) Carbon fibre and epoxy resin blades and connection arms 3 3.1 5 15.5 11 4.5 16 450 Turbines are mounted on 6m tilt down masts (shorter 3.4m alternative available for sites with space restrictions), or ground mounted on 15m tilt down mast 25 years (annual inspections recommended) Two years on components Cost of turbine: ÂŁ25 000 The aerodynamic helical blade design results in very smooth, quiet operation. Due to the vertical axis geometry of the rotor, the blade tips are close to the axis of rotation and travel a shorter distance per revolution. This results in a lower blade tip speed further reducing noise levels.
