4. SAFETY PRECAUTIONS
Our primary concern when we have developed the SILENTWIND Pro was your safety. The information
provided is to ensure your safety during mounting, operation, and in case of trouble.
If you have any additional questions, please contact us.
4.1 MECHANICAL RISCS
The blades are produced in carbon fiber and their aerodynamic shape have very sharp edges which
can cause severe injury in high wind conditions. For several reasons, the turning rotor system must
be handled with caution. You cannot see the end of the blades in high wind speeds, so you may not
recognize the inherent danger.
Always keep clear of the turning blades in all circumstances.
Never try to touch the turning rotor system.
Never try to stop the turning rotor system manually.
Blades can break due to ropes or other objects touching them in very strong winds
If one of the blades is damaged, immediately activate the BRAKE function using the stop
switch on Hybrid Boost Charge Controller. 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.
4.2 ELECTRICAL RISKS
A running SILENTWIND Pro can generate a considerable AC voltage and current per phase. High
voltage and current can cause serious injury and fire if you do not pay attention to safety.
Only person with appropriate technical skills and knowledge should carry out
the electrical installation.
Caution is recommended for people with cardiac pacemakers.
Never touch the open end of the wires.
The current when charging the batteries can reach more than 30A.
Careful to never short-circuit the battery.
Always provide enough ventilation for batteries.
To reduce installation problems, keep wire run as short as possible and mount all system
components as close to the batteries as possible.

March 2019
4.3 INSTALLATION RISKS
Please observe the following precaution during SILENTWIND Pro installation:
Do not install on a windy day.
Only use or build mounting/support system that can handle the load of the SILENTWIND Pro and
the blast pressure of the wind in any condition.
Make sure that nobody is close to the mast.
Before a storm the SILENTWIND Pro should be manually stopped with the stop switch on the
Hybrid Boost Charge Controller and one rotor blade must be fixed to the mast due to the risk of
damage by flying objects.
4.4 WHEN WORKING ON THE SYSTEM
Never work on the system during charging. The current is very high.
Major risk, severe injury or dead. Risk of fire.
Stop the system first by following the below sequence!
4.5 DISSASEMBLY SEQUENCE
1
st
Brake the wind generator. Tie the blades with a rope if possible.
2nd Disconnect the SILENTWIND Pro . If you have not tied the rope to the blades, to avoid
risks, once you remove the 3 wires from the generator please put at least 2 wires from
the generator together to cause a short circuit and slow down the rotation of the blades.
Use a tape to keep it on short-circuit.
3rd If you are using solar panels, cover them and disconnect them from the charge
controller.
4th Disconnect Battery. This is very important. Otherwise the Hybrid Boost Charge
controller will be damaged.
To assemble to equipment, follow the reverse order.

5. INSTALLATION
Before mounting the SILENTWIND Pro find a suitable position for the wind. The ideal position is when the
wind flows without any obstacles in the surroundings.
Please note that the SILENTWIND Pro can never be fully efficient if it is not mounted in the prevailing wind
direction or distracted by obstructions. Therefore, it is important to find a position without obstructions.
5.1 RECOMMENDATIONS
5.1.1 SITE
Make sure that you install the SILENTWIND Pro in a position where nobody can touch the
blades.
On a vessel, always ensure it is mounted at an enough height above the deck.
Further info on the following chapters.
Electrical assembly illustration

Silentwind Pro – User Manual
March 2019
5.1.2 THE MAST
The mast is a separated product and it is considered a third-party component.
On vessels, look for the advice on your vessel manufacturer or on your vessel maintenance company.
On land use, look for advice of a structural engineer.
The mast should be as short as possible but high enough that the blades do not interfere with any
objects and nobody can get hit by the blades. Usually at a height of 3 meters. Make sure that
SILENTWIND Pro gets “clean air”.
The mast must be well secured so that it is safe in strong winds and in adverse sea conditions.
The mast and the mast stays should be assembled in such a way that vibration will be not magnified.
The SILENTWIND Pro is a lightweight equipment but some precautions must be followed.
MINIMUM RECCOMENDED SPECIFICATIONS:
For marine applications, choose preferentially a marine grade stainless steel mast.
Aluminum masts are not recommended. Use aluminum masts only manufactured by certified
mast manufacturers.
The recommended diameters are 48 or 50mm.
The mast profile on steel, must not be less than 1,5mm thickness on 3m high maximum. The mast
must be anchored with rigid rods or steel cables (see the example below).
Use the proper anchorage.

March 2019
5.1.3 THE BODY
To avoid any damage to the powder coated aluminum housing please touch up any scratches, chipping of
paint work during installation. Sea water will penetrate the scratches and peel off the paint slowly.
As an additional precaution against electrolytic corrosion between dissimilar metals, you can use
“Duralac” or “Tefgel” on the 4 yaw bearing mast bolts/nuts.
5.1.4 ELECTRICAL INSTALLATION
Make sure all wires are placed in the correct position so that damage cannot occur.
The 3 AC cables need to have the same cross section and the correct mm²/AWG.
A damaged cable is a severe safety risk.
Wires with inadequate cross section can cause fire.
Make sure the electrical connections (crimping) are done 100%.
Any voltage drops can influence the control of brake functions.
Use tinned copper cables for marine installations.
When connecting Hybrid Boost Charge Controller to the battery, sparks can occur.
A short circuit is to be avoided.
Always ensure enough ventilation in battery location.
If the Hybrid Boost Charge Controller is not easily accessible, you can use a remote brake switch
connect with the external stop switch to the Hybrid Boost Charge Controller. You can choose the type
of stop switch suitable to your instrument panel.
Connect the mast or support to the ship´s grounding system whenever possible.
Check your battery specifications carefully. Read the battery manual if available.
If you are not qualified to perform electrical installations, don’t do it.
Work safely.
To execute the tasks, use the proper tools.
5.2 REQUIRED TOOLS AND EQUIPMENT
Mast with 48mm to 50mm diameter.
Extension cables to connect the three AC SILENTWIND Pro phases to the Hybrid Boost Charge
Controller.
Connectors for the three-phase cables and crimp plier

5.4 MECHANICAL INSTALLATION
5.4.1 INSTALLATION ON LAND
The height depends on the distraction of the wind by surrounding objects. You can simply test this
fixing 3 meters long by 4 cm wide strip of plastic at the top of 4 meters (or longer) pole. You can use
a second strip at 2 meters height.
If the upper plastic strip flows horizontally or up to 30 degrees from the horizontal you have found
the suitable position. In case the plastic strip shows more than 30 degrees from the horizontal or
turns around the mast, the position is unsuitable. This test should be carried out at moderate wind
conditions and must be considered as an additional information only.
We recommend doing several tests for an optimal site assessment. However, you do not need to
do this test if the SILENTWIND Pro is mounted far away from obstructions. You can also get help
from specialists on a small wind generators.
Having found a suitable position, an appropriate mast with suitable hardware must be chosen. The outer
mast diameter must be between 48mm to 50mm and it should be made of stainless steel or aluminum*.
Please also consider possible future maintenance work.
Earthing of the mast is highly recommended. On vessels you can use the central earthing point for mast
and engine. Ask a specialist for advice.
*Please check the aluminum mast maximum load with the manufacturer.
5.4.2 INSTALLATION ON A VESSEL
The assembly height must be chosen in a way that no member of the
crew is endangered by the rotor blades (around 3 meters). The
mechanical fixation of the mast foot must withstand the mechanical
loads occurring specially in rough sea conditions. We recommend
additional rigging to the sea rail or the deck of the ship.
Please consult your vessel manufacturer or your vessel maintenance
partner for advice.

Silentwind Pro – User Manual

Vessel/motorhomes equipped with wind generators typically have a dedicated mast used as the mounting
post for the wind generator.
Vibrations generated by all wind generators will be transferred down into the vessels hull or the
motorhomes walls via the mast and the fittings. These are called “harmonics”.
Therefore, how the mast is fitted to the deck/motorhomes is one of the most important parts of the
installation.
In order to eliminate harmonics and get best performance out of the SILENTWIND Pro we recommend the
following when installing on a vessel/motorhome:
Do not position SILENTWIND Pro in line with a backstay or centered position on your stern. It
needs to be positioned above the Bimini, coach house or any other construction. To work most
efficiently and with the lowest noise emission all wind generators need “clean air”. During the
wind tunnel testing it was clearly proven that any turbulence will decrease the SILENTWIND Pro
performance. The anemometer on a vessel is usually on a different Hight of the wind generator,
the windspeed shown will not be the same as on the wind generator. Please take this is account.
Avoid attaching the mast on any existing structure; for instance, a frame which holds solar panels,
Biminis, rail fitting, etc.
Use rubber inserts between deck and mast base, rubber washer for screws or bolts to remove any
latent vibrations before entering the hull/motorhome.
Use the supplied rubber insert between the SILENTWIND Pro and the mast.
All brackets, like mast clamps, need rubber strip insertions (3-4mm thickness and of medium
density) between parts.
An upper mast bracket should be installed approximately 20 cm below the lowest part of the
blades tip to stabilize the mast.
Once the mast is mounted you can start the installation of the SILENTWIND Pro.

5.4.3 SILENTWIND Pro ASEMBLY
1ST - CONNECT THE 3 BLADES TO THE ASSEMBLY HUB WITH THE ENCLOSED SCREWS
The fastening torque is 7-8 Nm equivalent to a
weight of 7-8kg on a 10 cm long lever arm, upright to the
lever arm. If the fastening torque is too high, this will
destroy or damage the blades. If the fastening torque is
not high enough, the blades can get lose. A wrong
fastening torque is a considerable safety risk.
Move each rotor blade in
running direction towards
the edge of the blade guide
of the hub. The running
direction is clockwise
looking from the front.
Before the final tightening of
the blade screws, make sure
that the distance between
the blade tips is the same, in
order to avoid vibrations.
Take a measuring tape and measure the distance from all three tips of the blades and adjust
accordingly (Approximately 990mm ± 5mm tolerance). The blades have been balanced statically
and dynamically.
An incorrect tightening torque represents a significant security risk. Regularly control
the fixation of the blades!
The enclosed nylon discs protect against electrolytic corrosion.

2nd FIX THE SET TO THE SILENTWIND Pro SHAFT WITH THE ENCLOSED SCREW NUT
(use the enclosed hexagon socket screw key).
The M16 Nut and the Hub is marked. The
arrow on the central nut should point towards
SILENTWIND Pro head. Do not over tighten
the central nut.
3rd SNAP THE NOSE CONE INTO PLACE ON THE ASSEMBLY
HUB
If possible, it is best to attach the hub with the blades
to the shaft at the very end of the mounting procedure.
After a week or so check the central nut which
connects rotor hub to shaft for tightness. Also check the 6
bolts which fix the blades to the hub.

4th MOUNT THE SILENTWIND ON THE MAST
Fix the 4 hexagon screws to the yaw clamp after
inserting the rubber pad.
When tightening the screws take care for a
uniform, circumferential tightening of the 4
screws.
The tightening should be made with small
increments in order to avoid damaging the
marine grade painting.

5.5 ELECTRICAL INSTALLATION
Make an extension of the 3 cables AC, using a crimp connector
insulated will be necessary since the SILENTWIND Pro will be
fixed in the mast and the Hybrid Boost Charge Controller will
not be fixed in the same place.
If there is enough wind speed when connecting SILENTWIND
Pro, this will immediately generate electric power at the end
of the 3 AC-wires without being connected to the Hybrid
Boost Charge Controller. Therefore, we recommend blocking
the SILENTWIND Pro blades with a rope before connecting the
wires to the Hybrid Boost Charge Controller.
Video Link - Silentwind Cable Connection:
https://www.youtube.com/watch?time_continue=1&v=1W4HlPHQ_C4
Connect insulating screw joints in the end of the wires coming from the battery. In case you do not use
the connecting wires, we recommend the use of crimp type cable sockets to connect your wires directly
to the Hybrid Boost Charge Controller.
Install a fuse between the Hybrid Boost Charge Controller and the battery positive pole, as
close as possible to the battery.

It’s very important that you first connect the Hybrid Boost Charge Controller to the battery
with the right polarity. The confusion of plus (red) and minus (black) will destroy your Hybrid
Boost Charge Controller.
After the connection of the battery you can connect to SILENTWIND Pro, the solar panel and if required a
load output with maximum 10A.
The 3 AC output wires must be connected to the 3-screw terminal on the back of the Hybrid Boost Charge
Controller. In a 3 phase AC system the connection order/polarity does not matter.

of the Hybrid Boost Charge Controller or from your smartphone or tablet using SILENTWIND Pro APP that
is available for Android and IOS devices.
The settings to operate the Hybrid Boost Charge Controller and SILENTWIND Pro are done through APP
or directly on the charge controller. The Hybrid Boost Charge Controllers are parametrized by default with
standard settings.
You must check all the parameters by yourself. Wrong settings can permanently damage your batteries,
your charge controller and your wind generator.
The Hybrid Boost Charge Controller must be adjusted according the type of battery and according to your
individual requirements. Please read the Hybrid Boost Charge Controller user manual.
End of charge Voltage – Batteries maximum voltage
Overvoltage – Load Output 1 and 2 Voltage protection
Low Wind Boost – set the boost to achieve an earlier start of charging in to the batteries
Storm Brake – Maximum amperage allowed. It will limit the maximum rpm speed and prevents
overheating.
Under Voltage Switch Off – To avoid fast discharging, below this value the Outputs are turned Off
Under Voltage Recovery On – Above this value, the Outputs are turned On
Solar Switch Off – Above this value, it will turn the Outputs Off
Solar Switch On – Below this value, it will turn the Outputs On
If the break adjustment and charge cut off voltage is reached, the SILENTWIND Pro will stop for
approximately 10 minutes.
If the capacity of the batteries is less than 150 Ah, or old batteries that have lost their original
capacity, the point of max. voltage can be reached very fast although the battery is not fully
charged yet. In this case it can be useful to connect an electric consumer to the Load-output,
as this will reduce the voltage and thus prevent that the break mode is activated too early.

7. MAINTENANCE
Your SILENTWIND Pro was manufactured for long term use without any maintenance. However, simple
and regular verification ensure the necessary security.
Before starting the verification, make sure the blades are stopped and the battery is not
connected to the Hybrid Boost Charge Controller. Please follow the DISSASEMBLY SEQUENCE
chapter.
The following verification should be carried out:
7.1 ROTOR BLADES
Check if the blades show damages like broken edges, damaged surface or cracks. If you notice any
damage, the SILENTWIND Pro must be immediately stopped.
7.2 SCREWS
Check that all accessible screws are correctly fixed. Especially the hexagon screws from the hub, the
central shaft nut and the fixing of the mast must be checked.
7.3 BEARING AND GASKETS
The bearing of the SILENTWIND Pro shaft and the yaw bearing of the shaft are permanently lubricated.
Check these bearings for free movement, or noise. Damaged bearing must be replaced.

9. FAQ
Could you please advise/confirm the 12v Wind.solar.hybrid set is suitable for marine use?
Our Hybrid kit is especially made for marine use, where we sell about 90% of our goods
The solar panels will be mounted on the push pit rail aft and will need to be able to swing from
vertical to horizontal. Do you include rail mountings in the package and price?
There’s no problem to use our panels horizontal or vertical. We don’t have rail mountings because
there are many different installation situations. You should check a suitable mounting system with a
chandlery nearby.
Please advise how to get the nose cone off.
To remove the nose cone, please just pull the nose cone out. The nose cone has three plugs that keep
it in place.
I have many Vibrations on the SILENTWIND Pro although the support is adequate.
90% of all the vibrations are due to the Mast Systems. Please use Rubber pads on all connections from
the Mast System into the vessel to absorb vibrations. Additionally, please check following points:
- Adaptor HUB – rotate the Hub to see if it is unbalanced.
- Nutt M16 – Check if uncalibrated - Replace Nutt.
- Rotor Blades - Blades Tips must have the same distance between the 3 blades.

12 QUICK INSTALLATION QUICK GUIDE
THE MAST / THE SITE
Vessel/motorhomes equipped with wind generators typically have a dedicated mast used as the mounting
post for the wind generator.
Vibrations generated by all wind generators will be transferred down into the vessels hull or the
motorhomes walls via the mast and the fittings. These are called “harmonics”.
Therefore, how the mast is fitted to the deck/motorhomes is one of the most important parts of the
installation.
In order to eliminate harmonics and get best performance out of the SILENTWIND Pro we recommend the
following when installing on a vessel/motorhome:
Do not position SILENTWIND Pro in line with a backstay or centered position on your stern. It
needs to be positioned above the Bimini, coach house or any other construction. To work most
efficiently and with the lowest noise emission all wind generators need “clean air”. During the
wind tunnel testing it was clearly proven that any turbulence will decrease the SILENTWIND Pro
performance. The anemometer on a vessel is usually on a different Hight of the wind generator,
the windspeed shown will not be the same as on the wind generator. Please take this is account.
Avoid attaching the mast on any existing structure; for instance, a frame which holds solar panels,
Biminis, rail fitting, etc.
Use rubber inserts between deck and mast base, rubber washer for screws or bolts to remove any
latent vibrations before entering the hull/motorhome.
Use the supplied rubber insert between the SILENTWIND Pro and the mast.
All brackets, like mast clamps, need rubber strip insertions (3-4mm thickness and of medium
density) between parts.
An upper mast bracket should be installed approximately 20 cm below the lowest part of the
blades tip to stabilize the mast.
Once the mast is mounted you can start the installation of the SILENTWIND Pro.

SILENTWIND Pro ASEMBLY
1ST - CONNECT THE 3 BLADES TO THE ASSEMBLY HUB WITH THE ENCLOSED SCREWS
The fastening torque is 7-8 Nm equivalent to a
weight of 7-8kg on a 10 cm long lever arm, upright to the
lever arm. If the fastening torque is too high, this will
destroy or damage the blades. If the fastening torque is
not high enough, the blades can get lose. A wrong
fastening torque is a considerable safety risk.
Move each rotor blade in
running direction towards
the edge of the blade guide
of the hub. The running
direction is clockwise
looking from the front.
Before the final tightening of
the blade screws, make sure
that the distance between
the blade tips is the same, in
order to avoid vibrations.
Take a measuring tape and measure the distance from all three tips of the blades and adjust
accordingly (Approximately 990mm ± 5mm tolerance). The blades have been balanced statically
and dynamically.
An incorrect tightening torque represents a significant security risk. Regularly control
the fixation of the blades!
The enclosed nylon discs protect against electrolytic corrosion.

2nd FIX THE SET TO THE SILENTWIND Pro SHAFT WITH THE ENCLOSED SCREW NUT
(use the enclosed hexagon socket screw key).
The M16 Nut and the Hub is marked. The
arrow on the central nut should point towards
SILENTWIND Pro head. Do not over tighten
the central nut.
3rd SNAP THE NOSE CONE INTO PLACE ON THE ASSEMBLY
HUB
If possible, it is best to attach the hub with the blades
to the shaft at the very end of the mounting procedure.
After a week or so check the central nut which
connects rotor hub to shaft for tightness. Also check the 6
bolts which fix the blades to the hub.

4th MOUNT THE SILENTWIND ON THE MAST
Fix the 4 hexagon screws to the yaw clamp after
inserting the rubber pad.
When tightening the screws take care for a
uniform, circumferential tightening of the 4
screws.
The tightening should be made with small
increments in order to avoid damaging the
marine grade painting.

https://www.youtube.com/watch?v=0avf_y2U3gY
ELECTRICAL INSTALLATION
Make an extension of the 3 cables AC, using a crimp connector
insulated will be necessary since the SILENTWIND Pro will be
fixed in the mast and the Hybrid Boost Charge Controller will
not be fixed in the same place.
If there is enough wind speed when connecting SILENTWIND
Pro, this will immediately generate electric power at the end
of the 3 AC-wires without being connected to the Hybrid
Boost Charge Controller. Therefore, we recommend blocking
the SILENTWIND Pro blades with a rope before connecting the
wires to the Hybrid Boost Charge Controller.
Video Link - Silentwind Cable Connection:
https://www.youtube.com/watch?time_continue=1&v=1W4HlPHQ_C4
Connect insulating screw joints in the end of the wires coming from the battery. In case you do not use
the connecting wires, we recommend the use of crimp type cable sockets to connect your wires directly
to the Hybrid Boost Charge Controller.
Install a fuse between the Hybrid Boost Charge Controller and the battery positive pole, as
close as possible to the battery.

It’s very important that you first connect the Hybrid Boost Charge Controller to the battery
with the right polarity. The confusion of plus (red) and minus (black) will destroy your Hybrid
Boost Charge Controller.
After the connection of the battery you can connect to SILENTWIND Pro, the solar panel and if required a
load output with maximum 10A.
The 3 AC output wires must be connected to the 3-screw terminal on the back of the Hybrid Boost Charge
Controller. In a 3 phase AC system the connection order/polarity does not matter.
