NOW WITH A FIVE YEAR WARRANTY!
Formerly the Whisper H40, the Whisper 100 has been updated
for 2005 with new features and added flexibility for your
renewable energy system. Now, any Whisper 100 can have its
voltage changed, 12-48V DC, within a few minutes in the field.
The Whisper 100 is designed to operate in a site with medium to
high wind speed averages of 12 mph, 5.4 m/s, and greater. The
100 provides 100+ kWh per month, 3.4 kWh per day, in a 12 mph
average wind. Worried about noise? The Whisper 100 is one of the
quietest wind turbines ever tested by the National Renewable
Energy Labs. Click on the link above for a copy of the noise
In addition to its patented smooth acting side furling
design, the Whisper 100 has a number of new features that make
it idea for any new or existing photovotaic system.
- A new four bearing spindle for a smoother operation and
- An upgraded Yaw shaft that more efficiently delivers
current to your batteries
- New bronze bushing and larger diameter furling pin for
smoother furling action
- New castings that allow easy access to the stator for
with every whisper is our new Whisper Controller. Unlike many of
our competitors, the Whisper controller includes a diversion
load to ensure quiet safe operation of your wind turbine when
the batteries are charged.
It installs in minutes and it protects both your wind turbine
and battery. The Whisper controller fits easily inside your
battery room. Add the optional LCD display and you will
instantly receive real time data on the performance of your
Whisper 100. The display can be mounted on the controller or a
1000 (300 meters) away letting you know what is happening. You
can even add an anemometer to your controller and now you can
measure wind speed and compare it to the output to make sure you
are getting the most from your Whisper 100.
Whisper 100 is designed for even the novice. The Whisper can be
installed in just a few hours with no welding, no concrete or
cranes. Our engineers designed the work out of installing wind
turbines. Now wind is as easy to use as photovoltaics.
Why small wind? Solar and wind resources often compliment each
other. Generally when it is sunny it is calm and when it is
cloudy it is windy. This complimentary effect is even greater
during seasonal changes. During the winter and spring when the
sun is at its least exposure, the wind is at it highest. A
Whisper 100 during these periods is essential to keep your
batteries charged and your lights on.
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. 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.
