Testimonials.
In
the end, it is what our customers say that really matters.
Here are the comments of some of them:
Johnny
Hanekom, Keetmanshoop, Namibia: The two (2) machines
that I've bought, exceed all my expectatoins as far as
power generation is concerned. I am really pleased with
their performance, and I am planning to buy the third
unit.
Johnny
van der Linde, Groblershoop: We are retired on our
farm outside Groblershoop, and have always experienced
a shortage of electricity from the solar panels we had.
With our Winglette wind generator now installed, we are
seeking ways to utilize the abandance of power thats available
now!
Nico
Grobler, East Coast, Mozambique: We have a holiday
home near Vilancuro, and are well please with our Winglette.
Being a pilot for the South Africa Air ways, I just love
the Winglette's modern technology and good look! |

————Charge
Controllers...
A
charge controller is an essential part of your Winglette wind generator system. Its purpose is to keep your battery bank properly
fed and safe for the long run. Your charge controller
has the basic function of blocking
reverse current and preventing battery over charging.
Blocking
Reverse Current.
Your Winglette wind generator, is fitted with a permanent
magnet alternator, that generates three phase Alternating Current
(AC). The controller rectifies this AC current to Direct Current
(DC), suitable to charge your battery bank. During times, when
the wind is not sufficient to produce a charge current, the
rectifying diodes in the controller,
block any reverse current that might leak from the
batteries, back to the wind generator.
Preventing
Over Charging.
When
a battery bank, when charged, reaches its full capacity, it
can no longer store the charging current with which it is presented.
If charging continue after the point of full load charge, the
water in the battery acid separates into hydrogen and oxygen
and start causing what look like the acid it boiling. This results
in loss of battery fluid and a rapid
degrading of the the battery life. The gasses the
are released are very corrosive and can even explode. The controller
has the purpose of preventing this situation.
Preventing
over charging is only a matter of reducing the power flow to
the batteries, when it has reached it full capacity. For 2Volt
cells, this normally occures at a value of 2.4Volt; for a 36Volt
system at 43.5Volts; and for a 48Volt system at 58Volt. The
controller will at this point reduces the current flow to the
batteries, but diverts excess energy to a special load that
absorbs the excess power. Your Winglette wind
generator may under no circumstances, be allowed to run freely. Free running of the rotor
might cause permanent damage to the blades in very high wind
speeds.
When
the battery voltage drops back to a lower value, predetermined
by the controller, it will reactivate full charging of power
to the battery bank. This is called voltage regulation. In essence,
the controller is looking at the battery voltage, and regulates
charging current accordingly.
Check
with you battery supplier,
what their requirements for voltage regulations are. If one
sticks to these prescribed requirements, you can be assured
of good functional batteries, that will serve you well for the
full life span, that they were designed for.
Display
and Metering.
The
controller include a variety of possible
displays. The most basic is a series of LED lights
to indicate to you the charged level of the batteries. This
is very handy to know at any stage, how full or how empty you
battery bank is.
You
can also have an Ammeter build into the controller, which will at any time , indicate
the charge current from your Winglette wind generator.
You can also buy the Power monitor,
which is a digital device that indicates, battery voltage, charging
current, watts charged, and keeps records of charging history
for the past 24 hours.
