The H40 is designed to operate in a site with medium to high wind speed averages of 12 mph, 5.4 m/s, and greater. The H40 provides 100+ kWh per month, 3.4 kWh per day, in a 12 mph average wind speed location. The H40, with its 7 ft. (2.1m) rotor diameter and 40 sq. ft. swept area, is rugged enough for extreme environments.

The redesigned H40 turbine incorporates a permanent magnet brushless alternator, which combined with Whisper's high efficiency composite airfoil blade design, delivers 900 watts peak power at 28 mph (12.5 m/s).

The H40 comes with the new EZ Wire II Controller that offers greater reliability and superior control for battery charging. Its compact, safe cabinet design features easily settable voltage regulation points, load dump and load dump isolation from the battery. The price of the system includes the H40 turbine and EZ Wire II Controller.

the side-furling Angle-Governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. Unlike other wind turbines that lose as much as 80% of their output when furled, the Angle-Governor allows the Whisper to achieve maximum output in any wind.
