|Wind, The Perfect Compliment to Any Solar System or
A Stand Alone Energy Producer
VAWTs (Vertical Axis Wind Turbines) accept wind from any direction, as
opposed to HAWTs which
have to constantly rotate so they face the wind Focus on output not
rated power Our
blade design is optimized for performance at typical lower wind
speeds. The result: higher annual
output - more kilowatt hours.
We provide an all inclusive package: turbine, controller/inverter, and
mounting system that is ready to use in four or five hours.
Certified Grid -
Our UL/CSA certified inverter is ready to be connected to a
bi-directional utility meter.
Eliminating the need for a tower simplifies installation and
significantly reduces your cost.
The ECO 1200 is designed to rotate at around 225 rpm versus 900 rpm for
competitors. Large rpms on other turbines result in vibration and noise.
Continuous Rated Output Power 1200 W
Continuous Output Voltage 120 VAC
Dynamic Loading: Peak Power Tracking Algorithm
Distortion less than 5% (2.5% typical)
Efficiency (Max) 94%
Temperature Operating Range 0-40 C; 32-140 F
Altitude Operating 4500m; 15,000ft

Electricity produced by wind generation can be used directly, as in
water pumping applications, or it can be stored in batteries for
household use when needed. Wind generators can be used alone, or they
may be used as part of a hybrid system, in which their output is
combined with that of photovoltaics, and/or a fossil fuel
generator.Hybrid systems are especially useful for winter backup of
home systems where cloudy weather and windy conditions occur
The most important decision when considering wind power is determining
whether or not your chosen site has enough wind to generate the power
for your needs, whether it is available consistently, and if it is
available in the season that you need it.
The power available from wind varies as the cube of the wind speed. If
the wind speed doubles, the power of the wind (ability to do work)
increases 8 times. For example, a 10 mile per hour wind has one eighth
the power of a 20 mile per hour wind. (10 x 10 x 10 =1000 versus 20 x
20 x 20 = 8000).
One of the effects of the cube rule is that a site which has an average
wind speed reflecting wide swings from very low to very high velocity
may have twice or more the energy potential of a site with the same
average wind speed which experiences little variation.This is because
the occasional high wind packs a lot of power into a short period of
time.Of course, it is important that this occasional high wind come
often enough to keep your batteries charged. If you are trying to
provide smaller amounts of power consistently, you should use a
generator that operates effectively at slower wind velocities.
Wind speed data is often available from local weather stations or
airports, as well as the US Dept. of Commerce,National Climatic Center
in Asheville,N.C.You can also do your own site analysis with an
anemometer or totalizer and careful observation. Installation of
generators should be close to the battery bank to minimize line loss,
and 30 feet higher than obstructions within a 300 foot radius. The
tower should be well grounded.
