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 looks |

————Battery
banks...
A
good sized, and well maintained, battery
bank, is the basis of almost all offgrid power generation systems,
whether wind power, solar power, or engine driven generators.
Battery banks are also the cause of most problems with independent
alternative energy systems. Batteries need to be replaces between
8 and 12 years, and consequently become expensive if poorly
managed.
We
have learned a great deal from forklift owners that use large
batteries to drive these machines, and recommend that
you use the following as guidelines:.
- Always
try to utilize the smallest size battery bank that will still be workable.
- Pay
particular attention the the protection of you batteries.
- Do
all things to stretch the life span of you batteries as much
as possible.
With
these guidelines in mind, we recommend that one rather choose a larger wind generator, or higher tower, than a
larger battery bank size. Acquire good measuring instruments
to determine the effectiveness of the battery cells. Keep batteries
clean and stored in a dry place.
A good size battery bank
for a 3kWatt wind generator is 400
ampere-hour. That means if you buy 2Volt cells, and
have a 36Volts system, buy 18 of 400 ampere-hour cells. If you
buy 12Volt, 100 amp-hr units, you will need 3 x 4 , that is
12 batteries.
The discharge rate, via your Inverter, should not be more
that 10% to 20% of the battery
capacity. In the Forklift industry, they use two sets of batteries,
one being charged, while the second is in service.
Keep
in mind that if your inverter draws 60 ampere form the system,
and you wind generator is charging at a rate of 45 ampere, that
your batteries are only discharging at a rate of 15 ampere.
Make
sure that your battery bank is charged
to full capacity at least once
a week. Batteries that are running, for long periods
of time, below their maximum capacity, looses its ability to
contain its designed full load capacity. To know whether a battery
bank is fully charged, measure its acid SG. It should be between
1.24 and 1.26.
It's
that simple.
