The robust Whisper 500 delivers serious
energy for your remote power needs. The
Whisper 500 performs well in harsh, high
wind environments with it’s two-bladed,
fiberglass-reinforced design. Patented
side furling overspeed protection
optimizes output at any wind speed.
Assuming a 12 mph (5.4 m/s) wind, a
Whisper 500 will produce as much as 500
kWh per month. That is enough energy to
power the about half the needs of
average California home.
Year-Round
Energy
Whisper systems combine well with photovoltaic
solar panels to balance out fluctuating solar
and wind resources. Generally, winter months
provide more wind and less sunlight, while
summer months provide more sunlight but less
wind. A hybrid system using a Whisper wind
generator provides year-round energy production.
Whisper
Controller
The Whisper 500 ships complete with a controller
and diversion load, ensuring quiet, safe
operation of your wind turbine when the
batteries are charged. The controller installs
in minutes and it protects both your wind
turbine and battery and easily fits inside your
battery room.
Add the optional LCD display to instantly
monitor real-time data on the performance of
your Whisper 500. The display can be mounted on
the controller or up to 1000 feet (300 meters)
away, so you can monitor performance in the
comfort of your home. You can even add an
anemometer feed to compare wind speed with
turbine output to make sure you are getting the
most from your Whisper 500.
Exclusive to the Whisper
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.
