Due to Silentwind’s continuous improvement process, we are happy to present you a new and improved wind generator – the Silentwind 400+. This generator has higher efficiency due to it’s earlier charging start-up. It also features faster wind tracking and stable operating performance due to an enlarged wind-deflector. The Silentwind 400+ has an additional body bearing for a more precise guidance of the wind generator and smoother operating. The new generator has reinforced mast support for higher safety reserves under strong winds.
