Part Number:

The Silentwind 400+ is the result of Silentwind's continuous improvement process. 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.
