AIR series

Go Where the Wind Takes You
Off the grid doesn’t have to mean out of luck. AIR small wind
turbines allow you to harness nature’s energy to power your day-to-day
needs practically anywhere on Earth with sustained winds. The
best-selling small wind generators in the world, AIR turbines are ideal
for sailboats, RVs, remote cabins and offshore platforms.
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 combining the two creates a perfect complementary
system for keeping your batteries charged. AIR systems are ideal wind
turbines for hybrid systems with solar to offset those cloudy or wintery
periods.
Choose from three models according to your energy needs.
WHISPER series

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).
Your property is at least 0.5 acre (0.2 hectare) and has unobstructed views
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.
