Total height: 107 cm
Material: seawater-resistant Aluminium
Spinning start: 0.5 - 1.0 m/s
Charging start 12.5 / 24.5 Volt: 3.0 - 4.0 / 5.0 - 6.0 m/s
Operating range: 0.5 - 30 m/s
Operating voltage: 0 - 59 Volts, optimised for 12-Volt applications
Operational noise: < Ambient noise / 30 dB max.
Dimensions of the rotor: B 32 x H 80 cm
Rotor nominal power at 12 m/s: 40 Watts
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 a mount 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.
