Rotor maximum power at 20 m/s: 187 Watts
Maximum generator efficiency: 96 %
Rotor type: Savonius rotor - 2 opposed C-shaped blades per level
Rotor features: Allrounder for gusty winds and all wind speeds, fast power delivery at low wind speeds, quick reaction to changing wind speeds, self-braking at high wind speeds
Mounting options: For example, with U-clamps for mast mounting, firmly srewed and/or removable on (top)/under flat surfaces; horizontal or vertical mounting possible (on walls, roof top, boat deck/mast etc.).

Important: To ensure long-lasting operation of your ALUMINUM wind turbine, always mount it in a holder at the top and at the bottom.
