Small, lightweight, efficient and very quiet 400w marine wind generator with hybrid charge controller.

Silentwind Marine Wind GeneratorsBuilding on the success of the extremely popular Silent Power Blades and the original Silentwind,  the SilentWind 400+ marine wind generator features the new hybrid 1000 regulator, a larger deflector and an additional body bearing providing improved efficiency, earlier start-up and better wind tracking as well as up to 550 watts of solar power capacity. Maximum efficiency at all wind speeds, safe, and very low noise, the Silentwind 400+ will be fitted to all 7 Boats in the 2014 Volvo Ocean Race.

See the Volvo Ocean Race Video for more information.

Silentwind 400+Aerodynamics from the aviation industry
- By using wind tunnel testing and advanced aerodynamics combined with a three phase permanent magnet generator, with Neodymium-Iron–Boron-(NDFeB) magnets, the Silentwind 400+ and Hybrid 1000 achieve an incredibly low start up speed of only 2.2m/s ( less than 4.3 knots) as well as a top output of 420w at only 1350 RPM, 30% less rotation speed than other 400w generators.

Silent Power Blades included as standard
 - Includes the incredibly quiet Silent Power Blades. Hand laminated, UV-resistant carbon blades, successfully tested according to DIN EN 61400-2 at hurricane speed 122 km/h (5480 rpm, with close to speed of sound at the blade tips). Almost silent with 70% less noise compared to other generators. This specially shows up in the frequency range between 1 and 12.5 kHz, that is most disturbing to human ears.
See Our Comparison video.

External Hybrid 1000 regulator, up to 550W of solar panels
 -  Silentwind features an external hybrid regulator with built in start/stop switch and multifunction LCD display for simultaneous use with both the Silentwind generator and up to 550 watts of solar panels, simplifying installation and cost on boats with both wind and solar power. The LCD display shows all relevant charging information and is adjustable for lead-acid, gel and AGM batteries. 

Marine aluminium powder coated body
- The compact aluminium body of the Silentwind is both lightweight and wind tunnel optimized for minimum noise. The elegant design will not look out of place even on the most stylish yachts.
