Safe - Quiet - Efficient - Building on the success of the extremely popular Silent Power Blades and the original Silentwind, Spreco has introduced the new designed SilentWind 400+ marine wind generator with improved efficiency, earlier start-up and better wind tracking with a larger deflector and additional body bearing. High efficiency at all wind speeds and very low noise.
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 achieves an incrediblly low start up speed of only 2.2m/s ( less than 4.3 knots) as well as a top output of 400w at only 1350 RPM, 30% less than other 400w generators.
Silent Power blades included as standard - Includes the incredibly popular Silent Power Blades. Hand laminated, UV-resistant carbon blades, successfully tested according to DIN EN 61400-2 at hurricane speed 122km/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.
External Hybrid Regulator, up to 100W 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 100 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 - Wind tunnel optimized for less noise.
Voted Best Choice - Skipper has voted the Silentwind as the best choice for all wind conditions. For an independent comparison of most wind generators currently available, see the following link. Tests performed on actual boats in real world conditions in the Caribbean.
Using a 12.5 volts conversion rate, we can compare output based on average wind.
7 knots - 830 Ah/month - 27 Ah/day
10 knots - 1790 Ah/month - 58 Ah/day
15 knots - 4460 Ah/month - 144 Ah/day
20 knots - 8600 Ah/month - 280 Ah/day
