Silent Power Blades

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 PRO and Hybrid MPPT 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 High Tech MPPT Hybrid Boost Charge Controller

Boost-Function: The adjustable boost function increases performance and optimizes the power yield, in light winds an earlier start of charging is guaranteed and an increase in performance is also possible in high wind regions.

Bluetooth-Function: The controller has a a built-in backlit LCD display showing all system parameters. This data can also be displayed on Android and IOS devices via a Bluetooth connection. Using this connection, system set-up and adjustments can also be done from a mobile device. The new external antenna increases range and improves connection.

Multi-stage charge process: After reaching the set charge voltage, the controller will switch to trickle charge mode, allowing a true 100% charge and avoiding battery discharge. Batteries are maintained in this full charge condition without the risk of gassing, an ideal solution for long battery life. The charge end voltage is adjustable for all battery types including Lithium.

Stop function: When the batteries are fully charged, the Silentwind PRO automatically stops or switches to trickle charge mode with a significant reduction in RPM. The Storm mode activates above a wind speed threshold to preventive damage and the new App features a stop function to remotely stop the wind generator directly from your mobile device..

Military grade components: By using certified military electronic components, the Boost Controller is insensitive to extreme temperatures, and remains stable even with electromagnetic interference.

Marine aluminium powder coated body
