1.3 Range of application
The electric power generated by the Superwind charges batteries and can
directly be used for 12 VDC or 24 VDC-appliances (depending on the system
voltage). AC-appliances are supplied via an optional inverter. There is a wide
range of high quality 12 VDC or 24 VDC equipment available like energy saving
lamps, refrigerators, deep-freezers, water pumps, ventilators, consumer
electronics, TV, radio and navigation equipment, etc.
Examples of ideal applications include sailing yachts, campers, summer cottages,
mountain shelters, and industrial applications such as navigational aids, security
systems, environmental monitoring stations and communications. For rural
electrification the Superwind supplies basic power to families, schools, small
health care facilities, etc.
In many integration sites, energy supplies from sun and wind complement each
other. That is why the Superwind is used in wind / solar and in combination with
other charging systems to optimize the availability of power (at minimized battery
capacity).

3 SAFETY INSTRUCTIONS
Please carefully study this manual before starting assembly and installation. The
information provided is to ensure your safety during mounting, operation, and in case of
trouble. If you have any additional questions please contact your dealer, a Superwind
service partner, or the manufacturer.
3.1 Potential sources of danger
Wind turbines in general – including small wind generators like the Superwind –
are electrical machines and thus potential sources of hazards.
3.1.1 Mechanical dangers
The main danger is the spinning rotor. The rotor blades are sharp and
can cause serious injuries, even at very low speed.
Never touch a spinning rotor.
Never try to stop the rotor by hand.
Do not mount the unit where personnel can come in contact with
the spinning rotor.
The rotor blades are made of carbon fiber reinforced plastic. This
material is extremely sturdy and enables your Superwind to cope with
heavy storms; however the rotor blades can break if any objects (e.g.
ropes, loose sail battens, branches etc.) come in contact with a spinning
rotor. The fragments of broken blades are sharp and can be thrown off of
the rotor at very high speed.
Protect the spinning rotor from impact with foreign objects.
For aerodynamic reasons the trailing edges of the rotor blades are very
thin and sharp.
Be careful when unpacking and handling in order to avoid injuries
as well as damage to the blades.
3.1.2 Electrical dangers
The generator can produce dangerous open circuit voltages up to 52
VDC (12 V version) and 105 VDC (24 V version) at no-load operation if
the electrical connection to the battery or consumer (load) is interrupted.
This open circuit voltage will be reached at a wind speed of
approximately 35 m/s.
The charging current will reach up to 30 Ampere DC (12 V version) or 15
Ampere DC (24 V version)! All wires, electrical components and
connectors must be rated for 40 Amps (12 V version) or 20 Amps (24 V
version). For correct dimensioning (gauge) refer to Section 6, Tables
6.3.1.1 and 6.3.1.2 on page 19.

V 01-2017 www.superwind.com
10
Smaller gauged wires with insufficient cross section
(diameter) will get extremely hot and can cause an electrical
fire.
To reduce installation problems, keep wire runs as short as practical and
mount all system components as close to the battery as possible. For
details see Section 6.2 on page 17
NEVER SHORT-CIRCUIT THE BATTERY. Doing so can
cause serious damage to the battery and wiring, such as fire,
explosion, and the release of acid toxic gases.
Be extremely careful to never short-circuit the battery.
Charging lead-acid batteries can produce dangerous
flammable gas. Unsealed lead-acid batteries have vent holes
releasing hydrogen during charging, which can form potentially
explosive gases in enclosed areas. A small spark (such as
from an electrical switch) can detonate this explosive gas
mixture. To prevent such explosions always provide sufficient
ventilation in battery storage areas.
Never install batteries in locations where the danger of sparks
exist.
Provide sufficient ventilation for batteries at all times.
The diversion load (power resistor) of the Superwind 350 charge
regulator (SCR type) can become very hot. This device requires
adequate space and ventilation to prevent the resistor from overheating.
To prevent damage to the device and to protect against fire, never mount
the power resistor on flammable surfaces or close to flammable
materials.
Never install the power resistors on a flammable surface.
3.1.3 Dangers when mounting
These instructions also apply during disassembly, when conducting
checks or other work carried out on your wind generator.
Only use mast and support designs capable of safely withstanding the
loads of your wind generator. The mast not only has to withstand your
wind generator’s weight and mass moment of inertia (e.g. on a sailing
yacht) but also the considerable thrust caused by high wind speed. For
details see Section 7 on page 27.
Work on the mast or on your wind generator only on a calm and windless
day. Do not step beneath or stand under hanging loads (e.g. a tilted
mast) and prevent other persons from doing so.

V 01-2017 www.superwind.com
11
Ensure that all batteries are disconnected from the system prior to
conducting any work.
Prevent your wind generator from starting unintentionally (turning in a
direct wind) during mounting by turning off the safety switch or short
circuiting the generator output wires (Red and Black).
Disconnect the battery before INSTALLATION! Short-circuit
the two generator OUTPUT WIRES (Graphic No. 3.1.3)
(Caution: Do this only AFTER disconnecting the battery!)
and/or loosely tie one blade to the mast without pressure to
prevent the blade from spinning during installation.
Never tie a rotor blade to the mast for long periods of time as
this will distort the aerodynamic design of the blade, resulting
in vibrations during operation which could damage the
generator.
Never approach a spinning rotor.
Never try to stop a spinning rotor by hand.
Never install the wind generator in areas where it can be
easily reached or approached by anyone while walking or
working around the turbine structure.

4. SPECIFICATIONS
4.1 Operational Free Space Required
The area where the Superwind turbine will be installed must be considered
carefully. Operational space for the turbine itself, as well as the working area
(including the mast and support) must be free from obstructions such as nearby
trees, walls or buildings, sailing equipment, etc. It is imperative that the turbine
operational area is completely unobscured and open to the wind to achieve
maximum energy production.
Wind turbine operations and safety are both optimized by careful preinstallation
planning. Clear, open air space provides the best air flow and performance, but
even ideal locations can be impacted by future changes to the area. Wind power
is dramatically affected by nearby structures, obstacles (growing trees, ship
bimini covers, etc), and even the turbine’s own mast structure. As such, it is
important for the installation to be designed with the end result and proper
integration in mind – such as including the highest practical mast top with the
clearest safety zone possible.

4.3 Functional description / Special features
The Superwind, like all wind turbines, uses part of the kinetic energy of the wind
and converts it into electricity.
The power is approximately proportional to the cube of the wind speed - i.e.
doubling the wind speed results in eight times higher power output. Therefore,
power from the wind at low wind speeds produces very little energy. However, as
the wind speed increases exponentially, high pressure suddenly impacts the
turbine and all of its mechanical components. During high wind events,
conventional wind turbine technology resulted in the turbine going into an “over-
speed” condition, damaging both internal electrical components as well as the
blades themselves.
To design the Superwind, special technologies were developed in order to
achieve optimum power output for a wide wind speed range, as well as maintain
maximum safety in high wind or storm conditions. The following technology has
been incorporated into the Superwind to achieve this performance.
a) The rotor blades were developed using modern computerized calculation and
simulation methods. The airfoil had been wind tunnel tested and was specifically
developed for small size rotors.
Relatively broad rotor blades combined with a special pitch angle produces a
high start-up torque, enabling the rotor to start at only 3.5 m/s wind speed.
Optimum start-up performance will be reached after a
mechanical run-in period of the bearings and their seals. This
‘break-in’ period will vary depending on the winds speed and
hours the turbine is left “on” in windy conditions.
When using the Superwind for battery charging, do not mistake rotor start-up for
the start of charging. The wind speed required to start charging the battery
depends on the battery charge load at the time and might be slightly higher than
the rotor start-up wind speed.
The term ‘cut in speed’ describes when the turbine can start producing power to
charge your batteries. This is a higher wind speed than the ‘start up wind speed’,
a lower wind value where your turbine may spin, but will not be producing power.

V 01-2017 www.superwind.com
14
At superwind, we focus on power production and not just turning blades. As such,
keep in mind that the wind speed required to start charging the battery depends
on the battery state of charge (load) and other basic electrical system factors.
Your turbine has extremely high quality bearing sets to provied
a long, nearly maintenance free service life. These special
bearings require a “ break in period“ of weeks or possibly
months to achieve the highest charging levels at lower wind
speed conditions. Leaving the Superwind turbine in the
autonomous “Run” position through all types of weather,
including high winds and storms, will help shorten this break in
period.
b) The basic innovation of Superwind is its novel aerodynamic rotor control system.
Similarly to large wind turbines, it adjusts the pitch angle of the rotor blades.
The mechanical controller is fully integrated into the hub and works without
expensive electrical or hydraulic components. Instead, the controller is actuated by
forces arising at operation of the wind turbine itself.
The forces are affected by the geometric and kinematic lay-out of the rotor and
controller mechanism.
Aerodynamic forces act as a control variable to adjust the rotor blades for power
regulation above the nominal wind speed. Centrifugal forces are the second control
variable for the rotor blade adjustment. By the special arrangement of both force
components, the controller limits rotor speed automatically (even at extreme wind
velocities) and protects the wind turbine from over-speed, even during no-load
operation. As a result, the controller limits the mechanical loads at high wind speed,
providing smooth operation under all weather conditions.

6. ELECTRICAL COMPONENTS AND CONNECTIONS
6.1 General information
Ensure that any installation or repair work on the electrical system is carried out
by qualified technicians only. These technicians must also read these instructions
prior to starting the installation!
Careful pre-installation planning is a crucial first step in the
installation of your new Superwind, as well as other
system components that are also part of your project.
The actual electrical connection should be made during the
lasts steps of the installation.
Make sure that the batteries and other charging sources (such
as grid or shore power) are disconnected until the installation
is complete.
6.2 Wiring diagrams
6.2.1 Recommended charge regulator
6.2.1.1 SCR Marine Charge Regulator (12V or 24V, depending on
turbine and system voltage, Graphic No. 6.2.1.1)
The SCR Marine charge regulator has been especially designed for use
with the Superwind 350 wind generator. It allows the user to fully charge
batteries, while also protecting battery banks from overcharging via a
diversion load control, as well as temperature compensation.
Wind charge controllers are very different from solar charge controllers in
that they are designed to electrically maintain the load correlation with
the battery bank while simultaneously producing power above the ever
changing battery state of charge. This allows the batteries to be properly
charged based on ideal temperature-compensated charging rates and
consumer demands.
The Diversion mode initiates when the batteries have reached their
maximum charging voltage; the SCR Marine´s PWM circuit automatically
diverts the wind turbine´s surplus power to the diversion resistor block.
With this technology, even when batteries are fully charged, the wind
turbine continues operating (provides useable power generated when
there is ample wind) providing real time power to other electric
consumers (loads) as they come online automatically or when switched
on manually.
This ‘Diversion State’ (dumping generated power) is indicated by an LED
illuminating (turning on) on the SCR Controller when the battery bank is
full – indicating that electric power (above and beyond the battery bank
charging needs) is available to be used rather than dumped.

V 01-2017 www.superwind.com
18
The SCR Marine Charge Controller is suitable for charging lead acid
batteries, gel batteries and AGM batteries (AGM = Absorbed Glass Mat)
and some Lithium Ion batteries (NOTE: consult your Superwind
Customer Service Contact and the battery manufacturer for important
specific details before trying to charge Lithium Ion Batteries!). For special
applications, the maximum charging voltage can be adjusted to customer
requirements by superwind.
The SCR Marine charge regulator is completely sealed and protected
against moisture (such as found in a marine environment) however it is
not waterproof and should be installed in a suitable weather proof
outdoor control panel or located in an appropriate dry space aboard ship.
The SCR Marine charge regulator has the ability to charge two separate
battery banks independently, yet still work in diversion mode when both
battery banks are in a full state of charge (eg. starter battery set and the
house battery bank on a yacht).
IMPORTANT:
An advantage of using the SCR Charge Controller is that it can work
alongside other charging technologies such as solar panels, diesel
generators, fuel cells, engine power (from the alternator), and even
shore power (aboard ship or at a site) without affecting other
operations.
Please contact your Superwind customer service contact for special
configuration information or more details.

6.2.1.2 Diversion Load Resistor
The resistance of the cable that connects the load resistor with the
charge regulator can affect the charging voltage. Therefore, the
connecting resistor wire run should not exceed 1 meter with the
recommended wire gauge. If you would like to extend the resistor wire
beyond 1 meter, please refer to the AWG Wire Size Chart (Table No.
6.3.1.1 and 6.3.1.2).
Charge regulators are not protected against reversed polarity of
the wires (“+” & “-“), and will be damaged if connected
incorrectly! Connecting the wrong wire (line) polarity to your
Charge Controller will void the warranty!
Do not reverse the polarity of the wires.
If you want to use a different charge regulator than what is recommended
for use with your Superwind 350 (the SCR Marine charge controller: 12v
or 24v), make sure that it is a suitable shunt-regulator based device with
full time diversion load control. To insure you are not voiding the warranty
on your Superwind turbine, please ask your Superwind customer service
contact as many other charge controllers - especially those used for solar
photovoltaic systems - are unsuitable, since they interrupt the electric
circuit for voltage regulation and can render the wind generator into a
dangerous no-load operation!
6.3 System components
6.3.1 Wires
The cross sections (gauge) of the wires required depends on their length
and the rated voltage of your wind generator. After selecting the location
of the mast, measure the distance from the mast top to the battery and
then select the minimum cross section required on the basis of the
following tables. In order to keep the power loss of the lines as small as
possible, do not use lines with under-sized cross sections.
It is always
recommended
to use
stranded
(braded) wire.
Solid wire
should be
avoided.
