A new generation of wind turbine with silent power blades

Wind generators are a practical and effective investment. When the wind blows at anything more than 8 knots you will simply have all the power you need. It's possible to greatly reduce or even completely eliminate engine running for charging purposes in a yacht to achieve reduced engine hours and save valuable fuel when on a long voyage.

The Silentwind 400 Wind Generator is the result of Silentwind's continuous improvement process. This generator has higher efficiency due to its earlier charging start-up. It also features faster wind tracking and stable operating performance due to an enlarged wind-deflector. The Silentwind 400 Wind Generator 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.

Silentwind 400 Wind Generator Features:

• 3-phase brushless AC-generator with permanent magnets
  
• Available in 12V / 24V or 48V
  
• Weight: 6.8kg
  
• Low noise emission
  
• Hand laminated, UV-resistant carbon fibre (CFRP) - rotor blades; successfully tested in the wind tunnel at hurricane wind-speeds of 122km/h, creating 5480rpm with sonic velocity at the blade tips
  
• Very good start up performance due to low cogging torque at 2.2m/s wind speed
  
• Fast chargfing start-up
  
• Universal application at low, middle and high wind speeds
  
• For marine and land-use and professional applications
  
• Durable and low maintenance
  
• Includes an external Hybrid-Charge Controller with LCD display for all relevant operational data as W, A, V, Ah, kWh
