1. Can the Kiss
Extractor™ be used with other wind generators?
a. Yes. The
Extractor™ will work with any three-phase generator with a nominal 12V and less than 45 amp output.
Extractor™ will Stop or slow the blade rotation when the batteries are charged.
Extractor™ will enhance the wind generator output at low wind speeds. However,
tuning of the Extractor™ must be performed to retain optimum output at all wind
Extractor™ will Stop or slow the blade rotation, if desired, to prevent wind
generator overheat. But the overheat set-point may not be right for other wind
2. How does the
Extractor™ Stop the blade rotation?
rotation is stopped by shorting the three phases of the wind generator through
b. This is
similar to flipping the Stop switch on the old Kiss controller. But the old
Stop switch had contacts that might develop corrosion and wear, reducing the
c. By using
solid-state switches there is no corrosion or wear and Stops have better
d. The blade
rotation will only be slowed depending upon wind speed. At wind speeds below
~42 knots, the blade rotation will be stopped or slowed. Above ~42 knots, the
Kiss will freely rotate and overheat.
3. What is
meant when the batteries are charged?
batteries are charged when they reach a user selectable voltage or 12.6, 13.2,
13.6, or 14.4V.
b. This charge
voltage is an estimate only. The Extractor™ has proprietary circuits that
improve the battery charge estimate despite constantly varying charge currents
from the changing wind speeds and wind generator output.
c. But, for
example, if the Extractor™ charge voltage is set for 13.6V, the Kiss will be
Stopped usually within +/- 0.2V of the setpoint.
4. What happens
when the Kiss overheats?
a. The Kiss
wind generator has thermostats inside that disconnect the phases from each
other when the Kiss heats up.
b. Once the
phases are disconnected the Kiss blades rotate freely and noisily in the wind.
No power is produced and no more heat is generated inside the Kiss. The
Extractor™ automatic and manual Stop switches will not stop the Kiss from
rotating when overheated.
c. If the Kiss
cools down, the thermostats will reconnect the phases automatically. Once
reconnected, the Kiss will again generate power, but it will also generate
heat. Since the Kiss is already warm, that heat will quickly overheat the Kiss
again. In high winds, the overheat and cooling cycles might be so fast that one
does not notice that the Kiss is being connected or disconnected. It spins
madly, creates vibration, and leads to stress on board.
d. If the winds
do not abate, the only way to stop the Kiss safely is to rotate the Kiss out of
the wind by pulling on the tail. Once the Kiss has cooled down, the automatic
and manual Stop switches will prevent or slow blade rotation.
5. What causes
the Kiss to overheat?
a. The Kiss
will overheat when producing greater than 22 amps for a period of time.
b. This is just
an average. The Kiss will overheat if there is a burst of wind causing it to
produce greater amp output.
c. It is
important to note that if the Kiss is producing greater than ~15.5 to 17 amps
for a period of time, it cannot be automatically or manually stopped by the
Stop switches. That is because when a Stop occurs, an enormous amount of heat
is generated inside the Kiss to cause the Stop. This extra heat sets off the
thermostats and disconnects the phases.
6. How does the
Extractor™ overheat Stop work?
Extractor™ circuitry monitors the average current production over a period of
time and initiates an automatic Stop when that average goes above 15.5 amps.
This output occurs in ~20 knot winds.
Extractor™ may not always Stop before the Kiss overheats. For example, suppose
there is a continuous 18 knot wind and then a sudden gust. The Kiss is already
warm because of the continuous work, but the gust produces a burst of energy
production and heat. The Extractor™ tries to Stop the Kiss, but just stopping
the blades in the gust may lead to overheat of the Kiss.
c. If the Kiss
still overheats, try turning the overheat trim pot counterclockwise a few
turns. Or, you may want to replace the thermostats in the Kiss.
7. I want more
power out of the Kiss and don’t want the Overheat feature. How do I turn it
a. The Overheat
feature can easily be turned off by opening the Extractor™ enclosure and
flipping the left dip-switch down on the circuit board.
b. When the
Overheat feature is off, the Kiss will give the same maximum output as a
non-Extractor™ Kiss. The low wind enhancement will still work and the automatic
battery voltage Stop function will still work.
8. Why does the
Extractor™ have the choice of Charge Voltage Stops?
customers have different needs, batteries, and battery charging philosophies.
b. The 12.6V
setting is for use with some lithium ion batteries. It is often harmful and
possibly dangerous to overcharge lithium batteries. The Charge Voltage rotary
switch should be set to 12.6V and the Enhancing Voltage dip switch should be
set to 12.6V as well, for some lithium batteries.
c. The 13.2V
setting might be used when the Kiss is being used to maintain a certain amount
of charge on the batteries during long term storage. If wet cell lead acid
batteries are only charged to 13.2V or less, they will not produce gas bubbles
in tropical conditions. This means that there will be no loss of electrolyte.
The batteries will still be wet at the end of the storage period.
d. The 13.6V
setting is near the recommended float voltage for many lead acid batteries.
Using this setting ensures that lead acid batteries will not be harmed when
charging via the Kiss.
e. The 14.4V
setting is for those that desire maximum battery charge. Continuous charging at
this voltage or to this voltage may decrease battery life when charging with a
f. The Charge
Voltage feature cannot be turned off. For those wishing to “disable” the
feature, set the Charge Voltage to 14.4V.
9. How do I
know when the Enhancement feature is working?
a. When the
Extractor™ is enhancing low wind performance; one can hear a faint “tea kettle”
like sound when standing near the Kiss. You can also sometimes hear it near the
b. The right
most rocker switch turns the low wind enhancement feature on and off. If you
are monitoring the current output of the Kiss you can note the change in output
when the rocker switch is turned On or Off.
10. I hear radio
noise associated with the Kiss. How to I reduce the noise?
Extractor™ enhancement feature may create radio interference at certain
frequencies. Try pushing the On/Off switch to the Off position.
Extractor™ enclosure is not grounded. Try running a ground wire from Bat – to
the enclosure. Or try connecting the enclosure to a ground plane strap.
c. If the noise
continues after trying the above, flip the Blade Rotation switch to Stop during
radio operation. If the noise continues, it’s not the Kiss or the Extractor™.
1 11. How tight should the cable nuts be? Use ~29 in-lbs to tighten the nuts.
12. During high
wind periods, the Extractor™ enclosure gets hot. What should I do?
Extractor™ enclosure provides the heat sink cooling for the circuitry inside.
Generally if the enclosure does not feel to hot to touch (i.e. less than 140°F
or 60°C) everything is operating normally.
enclosure should be mounted on a vertical surface such that air flows in the
gap between the wall and the bottom of the enclosure.
