SMA Technologie AG Introduction
Operating instructions WB11_17-11:FE4205 Page 9
1 Introduction
The Windy Boy inverters make it possible to operate small wind turbines as grid-con-
nected systems. Grid-connected means that the energy generated by the wind turbine
can be fed directly into an existing house power grid, a stand-alone power system,
or the mains grid.
To this end, the inverter converts the direct current (DC) from permanent-magnet wind
turbines, which varies with speed, into grid-compatible alternating current (AC). The
inverter requires the constant presence of mains-grid voltage!
The Windy Boy complies with all the VDEW (Verband der Elektrizitätswirtschaft –
German Electricity Industry Association) regulations for the connection and parallel
operation of electrical power units to the low-voltage grid of the electricity supply
company. This also encompasses the regulations of the German Professional Associ-
ation for Precision Engineering and Electro technology relating to "Automatic switch-
ing of electrical power units" (SMA grid guard) and/or DIN VDE 0126. In addition
to this, the Windy Boy conforms to the electromagnetic tolerance regulations and the
low-voltage regulations of the relevant combined European norms, as confirmed in
the CE conformity declaration (9.3 "Declaration of conformity (CE)” (page 61)).
The documentation provided here covers all such topics that are of interest when op-
erating the Windy Boy inverters. In addition to explanations of the operational meth-
ods of the device and detailed technical data, advice as to data capture and analysis
is also provided.
Information relating to the installation and commissioning of the Windy Boy should
be taken from the installation instructions delivered with the device. The Windy Boy
inverter has a special operation mode for wind turbines which allows performance
adjustment to the characteristic curve of the generator. In this way you will obtain
maximum yields from your wind turbine.
A wide input voltage range, high efficiency and a freely configurable output charac-
teristic curve with the highest level of reliability are only some of the properties that
are useful for your grid-connected system, or in a stand-alone system when combined
with the Sunny Island.
The installation of the Windy Boy 1100 / 1700 may only be done
by qualified technicians. The installer must be approved by the
utility company. Please read the installation guide carefully before
you begin with the installation. The installation of utility interactive
power sources must be compliant with all applicable regulations of
the utility company and with all applicable regulations and
standards.

Introduction SMA Technologie AG
Page 10 WB11_17-11:FE4205 Operating instructions
The Windy Boy is compatible with all SMA communication products (RS232, RS485,
Powerline, Wireless, Display), providing numerous possibilities for diagnosis, data vi-
sualization and remote maintenance of your small wind turbine system.
Apart from the parameter settings, the Windy Boy is identical to the Sunny Boy pho-
tovoltaic inverter and can therefore also be used as a PV inverter. Please download
the Sunny Boy manual from www.SMA.de. If you are planning to use the Windy Boy
in a photovoltaic system please contact us on the SMA hotline.
For stand-alone systems, that use the Sunny Island: Please configure your
Windy Boy according to the specifications in the Sunny Island manual.
Configuration of the V/I properties of the Windy Boy with respect to your wind
turbine: the parameters UPVStart, UDCWindStart and UDCWindMax must be
configured to guarantee optimum operation of your Windy Boy with your wind
turbine. The configuration process is described in chapter 5 "Turbine opera-
tion” (page 31).

2 Safety Information
Opening of the device, and any
•electrical installation,
•repair or
•modification
of the Windy Boy may only be performed
by qualified electrical personnel. Even
when no external voltage is present, the
device can still contain high voltages and
the danger of electrical shock.
The temperature of individual parts of the case of the Windy Boy -
in particular the temperature of the heatsink - can reach over 60 °C
in normal operation. There is the danger of burn injury when these
parts are touched!
The Windy Boy contains an independent mains disconnection device, the "SMA
grid guard". It ensures that the Windy Boy complies with the VDEW (Verband
der Elektrizitätswirtschaft – German Electricity Industry Association) regula-
tions for the connection and parallel operation of electrical power units to the
low-voltage grid of the electricity supply company (EVU) and with DIN VDE
0126, which forms a part of these regulations.

3 Unit description
3.1 Appropriate usage of the Windy Boy
The Windy Boy is designed for the conversion of DC voltage from a wind turbine
(permanent magnet generator) into AC voltage for feeding into the public mains grid.
The technical data is described in more detail in chapter 8 "Technical data”
(page 47).
Many wind turbine manufacturers offer an extra over-voltage protection module.
These components prevent the destruction of the downstream inverter in the case of
overvoltage.
Overvoltage can occur under the following conditions:
• High turbine rotation speeds under strong wind conditions
• An increase in turbine rotation speed caused by load-shedding when the inverter
is disconnected from the mains grid e.g. in the case of mains interference or po-
wer outage.
The overvoltage protection system has the following tasks:
• When a pre-defined voltage is reached, the inverter is disconnected from the ge-
nerator and a short-circuit slows the generator and/or brings it to a standstill.
• Some devices reduce the turbine rotation speed, and thus the generator output
voltage, by switching in a resistor assembly (Dumpload). The electrical energy ge-
nerated by the turbine is then converted to heat.
In grid-connected systems, we recommend the use of one of the electronic protection
mechanisms described here. Please note that overvoltage on the inverter can lead to
destruction of the device. In addition to this, you lose the right to all warranty claims
- even if the maximum input voltage of the inverter is only exceeded for a short time.

The electronic protection systems described here are preferable to mechanical solu-
tions (pitch control, "turning out of the wind") in every case.
Any other use of the Windy Boy leads to loss of the right to all warranty claims.
The presence of excessive input voltage can lead to irreparable
damage! Immediately disconnect the DC input of the Windy Boy.
When the Windy Boy receives an excessive DC input voltage, it automatically
disconnects from the mains network and no longer feeds power into the grid.
When the Windy Boy is in operation, you must always first disconnect the AC
voltage (mains supply) and only then should you disconnect the DC voltage
from the Windy Boy!

3.2 Device construction
An attractive, functional design is one of the major design objectives of the entire
Windy Boy product range. In its basic configuration, the Windy Boy has the proven
status display consisting of three LEDs. An extra display can be provided already in-
stalled or can be retrofitted.
As long as it is installed and commissioned according to the technical specifications,
the Windy Boy can be operated without any further modification or configuration.
The device parameters can however be modified, if required.
An extra communications interface is required for ideal adapta-
tion of the Windy Boy to suit the particular wind turbine being
used, and this can also be used for reporting operation data. For
further details, please refer to chapter 7 "Expansions” (page 39).

3.3 Operating modes
The operational status is displayed using three light-emitting diodes (LEDs) in the cov-
er of the Windy Boy. To allow the device to signal its operational status via the inte-
grated LEDs, the Windy Boy must be connected to the DC side of the system. There
must be enough wind energy present, so that the Windy Boy has adequate DC volt-
age.
A complete description of the possible displays can be found in chapter 3.3.4 "De-
scription of the operational status” (page 19). These can be split into three catego-
ries:
3.3.1 Normal operation
As long as the green control LED is on, or blinking, the Windy Boy is operating nor-
mally. The simultaneous illumination of all three LEDs is also an indication of normal
operation ("Initialization"). All other displays are a sign of abnormal operation.
Especially in the first year of operation, the operator of the system should
check this display under different wind speeds.

3.3.2 Critical, faulty operation
A comprehensive safety concept limits the number of critical conditions that can occur
to a single situation:
Input voltage exceeds the permitted value
This is indicated by the following blink-code on the yellow LED:
The yellow fault LED illuminates for 5 seconds when the fault occurs, and then begins
displaying the blink code of: 3 seconds off and then 4 times briefly on. This code is
displayed three times in succession. If the fault is still present, the fault display starts
again from the beginning.
3.3.3 Non-critical, faulty operation
All other fault codes indicate some form of faulty operation, which are not usually
dangerous to people or equipment, but which should nevertheless be investigated
and corrected.
Despite all precautions, it is possible that other faults may occur that cannot be dis-
played (e.g. failure of the status display). In order to recognize such faults, the oper-
ator of the system should use the explanations in chapter 3.3.4 "Description of the
operational status” (page 19) to check the plausibility of the displayed status.
Further detailed diagnoses are possible using the communication options detailed in
chapter 7 "Expansions” (page 39).
The presence of excessive input voltage can lead to irreparable
damage! Immediately disconnect the DC input of the Windy Boy.
When the Windy Boy receives an excessive DC input voltage, it automatically
disconnects from the mains network and no longer feeds power into the grid.
When the Windy Boy is in operation, you must always first disconnect the AC
voltage (mains supply) and only then should you disconnect the DC voltage
from the Windy Boy!

3.3.4 Description of the operational status
No (or low) input voltage
The Windy Boy is in Standby mode. This
situation occurs when the input perfor-
mance is too low for feeding the mains
grid (DC input voltage < approx. 80 V)
and for satisfying the on-board power re-
quirements.
Initialization
The on-board computer of the Windy
Boy is presently in the initialization pro-
cess. The DC input voltage of the Windy
Boy lies between approx. 80 V and ap-
prox. 120 V. The power is adequate for
the on-board power requirements but in-
sufficient for mains-grid feed-in or for
data transmission.
Working mode
The Windy Boy has successfully passed
the measurement electronics and SMA
grid guard self-tests and has begun feed-
in operation.
The Windy Boy is working normally and
is feeding electricity into the mains grid.
It is converting the DC voltage from the
wind turbine according to the V/I char-
acteristic curve defined by <UPVStart>,
<UDCWindStart> and <UDCWindMax>
(chapter 5 “Turbine operation" on
page 31).
All LEDs are off.
All LEDs are on.
Green LED is on.

Unit description SMA Technologie AG
Page 20 WB11_17-11:FE4205 Operating instructions
Stop
The Windy Boy is in Stop mode. Among
other functions, the measurement elec-
tronics are calibrated and then finally,
the device switches to "Waiting" mode.
The "Stop" mode can also be manually
set by the system operator via the Sunny
Boy Control or the Sunny Data PC pro-
gram. In this case, the Windy Boy re-
mains in "Stop" mode until a new
operating mode ("MPP mode", "Turbine
mode") has been set.
Maintenance, grid monitoring
The Windy Boy checks if the initial condi-
tions necessary for feeding the mains
supply are satisfied (e.g. start voltage)
and then begins monitoring the mains
network.
Derating
The temperature monitoring of the
Windy Boy has reduced the output per-
formance to prevent the device from
overheating. If this occurs often, then this
is an indication of inadequate heat dissi-
pation.
To avoid unnecessary reductions in
yield, in this case it should be checked if
the Windy Boy can be mounted in a bet-
ter position with better ventilation.
