Feed-in begins at  2.5 m/s wind speed  after start-up, depending on the repeller. Wind turbine specifically designed for inland locations with weak to moderate wind conditions. For average wind speeds of more than 6.5 m/sec., a repeller with  a diameter of 4.40 m is  used.

Wind and most hydro turbines require electricity, which is delivered at different power levels depending on the speed or turbine voltage. Also known as a power curve, this curve is typically non-linear. In the past (up to 12/31/2017), wind inverters have had the ability to enter a power curve. Our inverter control unit enables power curve control for ABB inverters, including the Trio (3-phase) and Uno (1-phase) DM series inverters.

The  Sunny Island 3.0M / 4.4M  is the ideal product solution  for self-sufficient and grid-connected systems  in the  power range from 2 to 13 kilowatts .

Lattice and tubular masts with heights of up to 30 metres  are   available for the  ANTARIS small wind turbines . The  lattice masts  also offer the option of attaching an advertising space.

NdFeBo permanent magnets, these are the strongest permanent magnets currently in existence. No cogging torque and no maintenance! To ensure long and maintenance-free operation of the generators in the ANTARIS wind turbine, the copper winding in the stator is designed in insulation class H (180°C)!  Since the repeller is attached directly to the generator shaft, BRAUN Windturbinen GmbH uses special ball bearings to safely absorb the resulting axial and radial forces.

The repeller blades have a computer-aided, aerodynamic profile and are manufactured using a hand-lamination process. The mix of glass fiber and carbon fiber laminate ensures the highest quality standards at a reasonable price.
