Applications and
power use
Essential facts on how to make the most
out of renewable energy
-
If
possible, only use 12v DC equipment (lights, CCTV cameras, fans,
heaters, fridges or kettles).
-
Do
use the electric power generated by your wind turbine directly as
much as possible. Charging batteries is only 50% efficient.
-
Avoid converting
power as much as possible, be it from AC to DC or DC to AC. Every time
the power is converted, you will lose 25% to 30% of the power.
-
To supply Mains power the
turbine has to charge batteries first, and then convert the power to
230v 50Hz AC. This means that only 20% to 30% of the power can be
exported.
-
Never use AC
(mains powered) equipment on a DC system. It will not work!
-
Using a DC/AC inverter to
power AC equipment from a battery should not be used over a long period
of time. Even when the inverter is switched off it will consume power.
Disconnect the inverter from the battery when not in use.
-
If there is no wind, an
AC/DC inverter disconnects it after 6 hours. If there is a battery bank
then the inverter can be connected over a longer period of time.
-
When the set-up is left
alone over a period of time it is essential to have a dump load
connected to the battery charger. Overcharging will damage the battery.
-
Always connect the
negative terminal (black) first, and then the positive terminal (red).
-
Always disconnect
the positive terminal (red) first, and then the negative terminal
(black).
Installation of
250W and 500W turbines for battery charging
To produce enough power to charge a large
Battery Bank, multiple 250W, 500W Turbines and Solar panels are
required.
It is essential to follow
the written instructions in the manual as well as the instructions on
the turbine itself to assemble flat-packed turbines.
To install the turbine on
a mast please follow the mast manufacturer's instructions and plans.
For battery charging
follow the instructions set out by the manufacturer of the
charger-controller.
Failure to follow these
written instructions will void your product guarantee. No responsibility
is accepted for failing to follow instructions.
Grid inversion for
all turbine models
If you wish to have your
turbine connected to the Grid we would recommend using either our Grid
Inverter, or to use a Grid Inverter recommended by your Grid supplier.
Please note, however,
that our 250W and 500W turbines are primarily designed to charge
batteries or battery banks.
Industrial and commercial applications
The
silent wind turbine by Luethi Enterprises can be scaled up or down
according to the usage and output required.
|
Security and CCTV cameras:
in remote, inaccessible areas without mains power or to save on
electrical and installation costs. Usage includes remote weather
stations and forest fire detection.
Streetlights and traffic management systems:
for rural locations or for governments looking for
environmentally-friendly renewable energy options.
Developing countries:
the silent wind turbine can deliver power to countries and regions who
have never had electricity before. What’s more, our turbines can be
maintained even by semi-skilled engineers.
Urban
environments:
the silent-running turbine enables factories, warehouses and
supermarkets to minimise their carbon footprint by utilising renewable
power (subject to local planning and resource consents). It is
important that the wind turbine is not in a wind shadow from trees
or tall buildings.
Advertising:
the large blades of the turbine present a new medium for outdoor
advertising. |

Domestic applications
|
Urban
environments:
the silent-running turbine now makes wind power a reality for city
dwellers (subject to local planning and resource consents) - provided
the wind turbine is not in a wind shadow from trees or tall
buildings.
Pay-back:
wind turbines can be used in many countries to sell power back to the
national grid, so your investment in renewable power could pay for
itself. (Contact your local power company for details.)

Rural
and lifestyle blocks:
finally, a realistic power solution for those living in remote areas
with a need or desire to generate their own power.
The
Silent Wind Turbine by Luethi Enterprises is ideal for remote locations.
Most other wind turbines need power to run their electronics, so these
turbines either need an external power source to run, or they draw a
significant percentage (up to 80%) of the power produced. This
drastically affects the power available to the end user.
With the
Silent Wind Turbine by Luethi Enterprises, 100% of the power produced is
available to the end user.
Battery charging:
the silent wind turbine is ideal for charging battery banks.
Installation examples
Due to
its innovative features, Luethi Enterprises’ silent wind turbine can be
sited in a range of environments, including rural and urban as shown in
these simulations
-
Stacked:
the silent wind turbine can be vertically stacked, with units sharing the
same central axis or as single installations.
-
Roof tops:
subject to planning constraints, the silent wind turbine could be
used on tower blocks in urban, rural or industrial flat-roofed
buildings. Even on these buildings, the wind turbine should be on a mast
to reach into the best airflow. Like most other wind turbine suppliers,
we would not recommend installing a wind turbine on a pitched roof for a
variety of factors.
-
Masts:
make the most of the higher wind speeds at altitude by mounting a
smaller-sized turbine on top of a mast or streetlight.
