It appears that the new generation wind generator SILENTWIND has changed that. Apart from the slight and inevitable noise due to wind turbulences, SILENTWIND generators can be almost noiseless.
Specially designed blades
It is the rotor blades for SILENTWIND that have been designed for efficiency and negligible noise. The design was extensively wind tunnel tested at hurricane wind speeds of 122 km/h or 5480 rpm, at which the blade tips almost reached the speed of sound. By using UV resistant Carbon Fiber (CFK) Blades and highest quality components, maximum accuracy and rigidity have ensured that the production quality of these products reliably match the design parameters. Designed and made by German engineers.
Silentwind generators come complete with a dedicated Hybrid Charge Controller. There is an option to connect solar panels of up to 180Wp. It is programmable for acid, Gel, AGM, Li-ion batteries. The controller will monitor the battery and as soon as the battery is fully charged, the generator will stop.
As soon the battery level drops it resumes charging. An integrated manual brake switch will override the electronic. A comprehensive display will show data like V, A, A/h or kW/h. There is no maintenance and it is easy to install.
The cost of the unit is about $1,995.00.
Upgrading existing AIR X or AIR Breeze wind generators
Sailors who already have the AIR X or AIR Breeze wind generators can now replace their blades with the new "Whispering" blades which will reduce the noise emission dramatically (70%) and will improve power output at the same time.
