Braun Antaris Windturbine

Information about Antaris Small wind turbines

The ANTARIS wind turbine is a wind energy system that is ideally suited to inland sites. It is designed specifically for feeding power into the grid, charging batteries (24 V / 48 V etc.) and for supporting heating systems.
As a result of its sturdy design, the ANTARIS is also suitable for locations exposed to storm-force winds, optionally with different rotor diameters (2.30m – 5.10m).

The hand-laminated rotor blades benefit from a computer-designed aerodynamic profile. Needless to say, each blade is statically and dynamically balanced, carries an identification number and comes with relevant documentation.

Uncomplicated from the aspect of configuration, importance has been attached to ensuring that these turbines can be quickly assembled and installed by hand. As a result of its robust design, the ANTARIS works with extreme efficiency and not only comes at a highly attractive price in its basic version. Particular attention must be drawn to its excellent start-up behaviour (at wind speeds as low as 2.2 m/s) and very quiet operation (49 dB). This means the system can also be installed in residential areas.

Grid-connected operation requires the Windy Boy inverters (Windy Boy 1100 - 5000TL) with characteristics matched to the ANTARIS and local wind conditions. Alternatively, in less windy areas, grid-connected operation is also possible with a Windy Boy 1700.
The inverters carry an appropriate declaration of conformity and are approved for grid-connected operation – the ENS (electronic grid guard system) is already integrated!
Inverter communication takes place through USB/RS 232 interfaces etc.; for more information, go to the "SMA" link.
When the ANTARIS is used in heating applications, a control cabinet with control electronics provides optimum control of the wind characteristic in conjunction with a 6000-watt heating element.
The azimuth bearing is configured as a double-support plain bearing equipped with lubrication nipples for re-greasing. The supporting element with generator and wind vane jib is fully galvanised (see picture gallery).

As power is conducted directly to the power consumer, a flexible cable is required inside the mast.
Storm protection: On reaching maximum power output, the ANTARIS goes into the helicopter-type rotor-blade protection position (see picture gallery), reducing blade area exposed to wind. In addition, the control electronics in the control cabinet monitor system voltage and slow the wind energy system down by means of braking resistances (6.0 - 12.0 kW) when maximum voltage is attained.
This option has clear advantages over generator short-circuit as the repeller's rotating movement is not actually interrupted. This ultimately improves the wind energy system's overall level of efficiency.

By way of option, the ANTARIS is also available with slip rings for collecting electrical power and no-maintenance azimuth bearings with double ball bearing!
