Whisper 500


Serious off-grid performance

The Whisper 500 delivers significant energy for battery-charging applications. Its simple and rugged design includes a corrosionresistant body and mechanical overspeed protection. Ships with a Whisper Controller, diversion load and display. Ships standard with corrosion resistant finish for coastal or extreme environments.


Exclusive to the Whisper, the side-furling angle-governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. This angle-governor lets the Whisper 500 continue to safely spin and deliver energy even in high winds.
