Wind turbine Braun Antaris 7.5 kW : Power, Efficiency, and Robustness

The Antaris wind turbine is especially well suited to inland sites. It can be used to charge 24 VDC or 48 VDC batteries and power heating systems. Thanks to its robust design, the Antaris wind turbine is also well suited to locations exposed to storms.

The rotor blades are hand-laminated and have a computer-designed aerodynamic profile, as well as being statically and dynamically balanced. Each blade carries an identification number and comes with its own documentation. The utmost importance has been attached to ensuring that this wind turbine is quick and easy to install.

Thanks to its robust, sophisticated design, the antaris wind turbine offers excellent performance at a highly attractive price. It starts up very quickly (already at a wind speed of 2.2 m/s) and operates silently (43 dB). This makes it ideal for installation in residential areas.
