Dear customer
We thank you having bought our product . You have decided on a new generation of
windgenerator. Compared to traditional windgenerators the essential advantages of
our product are safety, security, efficiency and very little noise emission. You will also
profit from our experience of more than 30 years with various windgenerators used
offshore sailing. For long distance cruising the availability of electric energy without
the possibility of grid connection is essential .
Fair winds at any time
The Spreco Team
Please note that this manual is part of the product and must be read closely. Please
study the information carefully before installing the Silentwind generator. This manual
should always be kept near the product and passed on to future owners.
This manual is addressed to the person installing the Silentwind generator. This
person should be familiar with electric wiring and the use of appropiate tools.
Otherwise the Silentwind generator should be installed by a specialist.

1. Operation and use
It´s most efficient to use the regenerative electric sources of both wind and sun
combined to charge your batteries so that you can make use of daylight and wind for
24 hours. Our hybrid charge regulator is suitable for both sources. You can also
charge the batteries of an electric vehicle with this unit.
Further applications are:
Any application without grid connection, research units, traffic management systems,
emergency systems, street lamps, billboard illumination, projects in developing
countries, wireless LAN access points, holiday homes with inverters for independent
provision of electricity wherever there is no grid connection available or too
complicated to install.
The Silentwind generator is ultralight and aerodynamic so that it is possible to
connect various windgenerators in case your need for energy is high. As noise
emission is very low you can opereate the Silentwind generator in neighbourhoods
and on sailing yachts without annoying your neighbours.
Our charge regulater is suitable both for 12 and 24 volt usage and can be connected
to the Silentwind generator and solar panel.
Another advantage of the Silentwind generator ist hat it does not have any inbuilt
electronics which means that there is hardly any maintenance work on the mounted
windgenerator. The electric power is led down to the charge regulator by three
cables. The hand laminated carbon fiber blades were successfully tested in a wind
tunnel up to wind speeds of 35m/s 63 knots according to DIN EN 61400-2. Therefor
you need not worry about the Silentwind generator in any storm conditions. For
maintenance work there is an additional manual stop switch.
2. Safety instructions
Due to the high RPM and the electric energy that windgenerators generate their use
may be dangerous. Therefore carefully read the following safety instructions.
2.1. Mechanical risks
For various reasons the turning rotor system must be handled with caution. You
cannot see the end of the blades in high wind speeds so that you do not recognise
the inherent danger. Due to their aerodynamic shape the blades have very sharp
edges that may hurt you in high wind conditions. Never ever try to touch the
turning rotor system ! Never ever try to stop the turning rotor system manually.
Make sure that you install the windgenerator in a position that nobody can touch the
blades. Especially on boats ensure a sufficient height above deck.
The blades are produced from carbon fibre which is extremely solid even in high wind
speeds. Therefore keep away from the turning blades in any case. However they can
break because of ropes or other parts touching the blades in very strong winds. If
one of the blades is damaged, activate the brake function manually with the stop
switch of the charge regulator. If one of the blades is damaged, the rotor system will
be out of balance which may be a risk for the whole mounting construction. This has
to be considered before mounting the windgenerator in a safe position.

Before you install the windgenerator on a mast construction make sure that the 3phase wiring is disconnected from the charge regulator or fix one blade so that the
system cannot turn. You can also connect the 3 AC wires to block the system whilst
mounting. Another possibility to install the system is to screw the hub with the blades
to the shaft at the very end of the mounting procedure. The mast must be well fixed
so that it is safe in strong wind and sea conditions. Please ask a professional who is
able to assess the load that the system generates in strong wind conditions.
2.2. Elecrical risks
An idle running windgenerator can generate an AC voltage of 40 volt AC /15amp per
phase. Only connect all components if you are familiar with electric wiring. The high
voltage can cause serious injuries and fire if you do not pay attention to safety. Never
ever touch the open end of the wires. The currents on charging the batteries can
reach more than 30 A DC. The whole wiring electric components and connection
points must be able to carry a current of 40 A. Find information about suitable cable
dimensions on page 9
Warning:
Wires with insufficient diameters can cause fire.
Make sure that the wires are run so that mechanical damages cannot occur. A
damaged cable is a severe safety risk. Install a fuse to the batteries positive pole as
closel as possible to the battery. In any case a short circuit of the poles must be
avoided.
Warning:
A short circuit can cause fire and explosion. Never ever install batteries where sparks
can cause this risk. Always ensure sufficient ventilation!
The electrical installation should be carried out by persons with suitable skills who
know what they do. Before a storm the Silentwind generator should be manually
stopped with the stop switch on the charge regulator. In case of storms we
recommend to fix one rotorblade to the mast because of the risk of flying objects.

2.3. Installation risks
Only use mounting constructions that can take the load of the generator and the blast
pressure of the wind in any condition.
Working on the mounting unit should only be carried out on a calm day. Make sure
that nobody is close to the mast.
Disconnect the battery from the charge regulator when working at the system.
The turning of the blades must be avoided by fixing one blade to the mast.
