Dependable Energy in Areas Where You Can’t Depend on a Power Company

Whisper wind generators capture the power of nature to provide energy to off-grid areas around the world. Whether you’re creating a hybrid system with wind and solar, powering telecommunications sites or water pumping, Whisper provides dependable energy anywhere there’s consistent wind.

Whisper’s patented side-furling design protects the turbine in high winds and maximizes output at any speed.

Will Whisper work for you?

Whisper has three models to accommodate your wind conditions and energy requirements. If your site meets the following criteria, there’s a Whisper model to meet your needs:

• At least 10 mph (4.4 m/s) average wind speed best results at 12 mph (5.4 m/s) or more
• Your property is at least 0.5 acre (0.2 hectare) and has unobstructed views
• The local zoning allows a structure that is at least 52 ft (16 m) tall. Your local Whisper dealer can help determine this

The small-wind system with big-ticket features

Whisper wind generators are designed and built in America with standard features you may not expect from a small-wind system, including the exclusive side-furling angle. Unlike other wind turbines that lose as much as 80% of their output in high winds, Whisper provides maximum output in any wind.

Every Whisper model also comes standard with the Whisper Controller, which includes a diversion load to ensure quiet, safe operation even when the batteries are fully charged. The Controller is easy to install in your battery room and protects both your turbine and your battery.

The Whisper Controller is also available with an optional LCD display that gives you instant feedback on your turbine’s performance. The display can be mounted on the Controller, or up to 1000 feet (300 m) away for remote monitoring. There’s also an optional anemometer to help you compare wind speed and output to make sure your turbine is operating efficiently.

Bringing the power of the sun and wind together. Naturally.

Combining wind power with solar is ideal for helping you meet your energy needs. In general, cloudy days tend to produce more wind and calm days more sun, so bringing the two together creates a perfect complementary system for keeping your batteries charged.
