SMA Technologie AG Introduction

1 Introduction

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.

The Windy Boy inverters make it possible to operate small wind turbines as grid-con­nected 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 Associ­ation for Precision Engineering and Electro technology relating to "Automatic switch­ing 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 op­erating the Windy Boy inverters. In addition to explanations of the operational meth­ods 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 charac­teristic 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.

Introduction SMA Technologie AG

The Windy Boy is compatible with all SMA communication products (RS232, RS485,
Powerline, Wireless, Display), providing numerous possibilities for diagnosis, data vi­sualization and remote maintenance of your small wind turbine system.

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 U

Start, UDCWindStart and UDCWindMax must be

PV

configured to guarantee optimum operation of your Windy Boy with your wind
turbine. The configuration process is described in chapter 5 "Turbine opera­tion” (page 31).

Apart from the parameter settings, the Windy Boy is identical to the Sunny Boy pho­tovoltaic 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.

Windy Boy

Public mains grid

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 po­wer outage.

The overvoltage protection system has the following tasks:

• When a pre-defined voltage is reached, the inverter is disconnected from the ge­nerator 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 ge­nerated 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.

Operating instructions WB11_17-11:FE4205 Page 13

Unit description SMA Technologie AG

The electronic protection systems described here are preferable to mechanical solu­tions (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 in­stalled 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.

3.3 Operating modes

The operational status is displayed using three light-emitting diodes (LEDs) in the cov­er of the Windy Boy. To allow the device to signal its operational status via the inte­grated 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 volt­age.

Grid tied inverter for wind turbines

Especially in the first year of operation, the operator of the system should
check this display under different wind speeds.

A complete description of the possible displays can be found in chapter 3.3.4 "De­scription of the operational status” (page 19). These can be split into three catego­ries:

3.3.1 Normal operation

As long as the green control LED is on, or blinking, the Windy Boy is operating nor­mally. The simultaneous illumination of all three LEDs is also an indication of normal
operation ("Initialization"). All other displays are a sign of abnormal operation.

Operating instructions WB11_17-11:FE4205 Page 17

Unit description SMA Technologie AG

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 LED

The message is repeated 3 times
and then begins again.

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.

The presence of excessive input voltage can lead to irreparable
damage! Immediately disconnect the DC input of the Windy Boy.

34

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!

3.3.3 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 dis­played (e.g. failure of the status display). In order to recognize such faults, the oper­ator 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 Windy Boy indicates a mains supply fault with this message, which can have the
following causes:

• Low mains supply voltage (VAC < "Vac-Min")

• High mains supply voltage (VAC > "Vac-Max")

• Low mains supply frequency (fAC < "Fac-Min")

• High mains supply frequency (fAC > "Fac-Max")

• A change in mains supply frequency ("dFac")

Check if a general mains supply dropout has occurred (check the operation of other
mains supply devices), and check if the fuse of the feed-in connection of the Windy
Boy is intact.

If none of these faults can be found, then the mains supply connec­tion of the Windy Boy must be checked by qualified electrical per­sonnel.

The Windy Boy has detected a fault relating to an unacceptable impedance in the
mains supply. If the Windy Boy frequently displays this fault during mains monitoring,
the cause can be a mains impedance that is too high. An electrician can usually assist
with this problem by increasing the cross section of the mains connection cable. Other
measures can be taken to correct this problem, but they require the agreement and
cooperation of the electricity supplier.

DISCONNECT DC

Overvoltage displays

Immediately disconnect the DC input of the Windy Boy. The pres­ence of excessive input voltage can lead to irreparable damage!
Make sure that the input voltage never exceeds 400 V.

Before placing the device back into operation, the input voltage must be
checked before reconnecting the DC voltage to the Windy Boy! Since the
Windy Boy is identical to the Sunny Boy, apart from the mode of operation,
the display shows "PV" (Photovoltaic) as its input source.

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.

If an excessive DC input voltage is present on the
Windy Boy, then this is indicated by rapid blinking of
the background illumination and a corresponding
message.

SMA Technologie AG Turbine operation

5 Turbine operation

5.1 Overview

The Windy Boy is a single phase inverter that converts DC current into AC current
and feeds the energy generated by a wind turbine into an existing mains grid.

The Windy Boy is externally identical to the Sunny Boy inverter for photovoltaic sys­tems.

The Windy Boy inverter has a special operational mode for wind generators howe­ver, which allows performance adjustment to the characteristic curves of many diffe­rent manufacturers' generators ("Turbine" operating mode). In this way maximum
yields can be obtained from your wind turbine.

The mechanical power of the wind turbine is presented to the inverter in the form of
a direct, rotation speed variable DC voltage (RPM) and current intensity (torque).

Most small wind turbines have a so-called permanent magnet generator and a down­stream rectifier for converting the variable frequency AC generator voltage into DC
current.

5.2 Characteristic curve function

The "Turbine" operating mode of the Windy Boy uses a programmable power/volta­ge curve to regulate the input current depending on the generator voltage (V/I cha­racteristic curve).

Every wind generator is designed to have an optimum working point for voltage and
current, at different rotational speeds or wind speeds. This behavior is not linear.

The Windy Boy uses an approximation based on a simple ramp function. The function
can be programmed by the user so that it comes close to the behavior of the wind
generator being used and thus provides power adaptation.

The feed-in AC power depending on the DC input voltage of the inverter is shown

The correct configuration of the parameters shown in the diagram is absolutely nec­essary to guarantee optimum operation with wind generators from different manufac­turers.

The basic parameters of a Windy Boy (factory settings) are shown in the following

The correct configuration of the parameters above is absolutely necessary to guaran­tee optimum operation with generators from different manufacturers. Preconditions
for changing the operating parameters are described in chapter 5.4 "General setting
example” (page 35).

To perform the configuration process, the DC input voltage must be greater
than <UpvStart> and the Windy Boy must be connected to the mains grid.

Operating instructions WB11_17-11:FE4205 Page 33

Turbine operation SMA Technologie AG

5.3 Characteristic curve operation in "Turbine" opera-

ting mode

Please note: The linear characteristic curve of the Windy Boy only approxi­mates the actual characteristics of a real wind generator. Consult the manufac­turer of your wind generator for the typical characteristics of your generator
before changing the characteristic curve parameters.

As soon as the DC input voltage defined in the parameter <UpvStart> is reached, the
inverter begins a number of self tests, measurement processes and synchronizes with
the mains grid. If the self tests are successfully completed, and the DC input voltage
remains above the value defined in <UpvStart> for the time defined in <T-Start>, the
inverter connects to the mains grid.

As soon as the DC input voltage reaches the value defined in <UdcWindStart>, the
inverter begins feeding power into the mains grid. As you can see from the charac­teristic curve, the power fed into the mains grid rises with the DC input voltage.

As soon as the DC input voltage reaches the value defined in the parameter <Udc­WindMax>, the Windy Boy feeds the mains grid with the maximum possible power.
If the input voltage continues to rise, the Windy Boy continues to feed the mains grid
at maximum power.

The characteristic curve ends at the maximum permissible input voltage of the Windy
Boy, which must never be exceeded.

If the wind strength is so low that the DC input voltage falls below <UpvStart>, then
the inverter ceases feeding power into the mains grid for the period defined in <T­Stop>.

If the DC input voltage increases again, then the Windy Boy will again operate ac­cording to the characteristic curve.

If the DC input voltage falls below the internally calculated minimum operating value
of <Umin>, then there is insufficient energy for the on-board electronics and the Win­dy Boy will switch off.

If the DC input voltage lies between <Umin> and <UpvStart> for the time defined by
<T-Stop>, then the inverter will also switch off.

After the switch-off process, the whole process begins anew.

Only change the operating parameters when you know exactly what you are
doing!

Page 34 WB11_17-11:FE4205 Operating instructions

SMA Technologie AG Turbine operation

5.4 General setting example

Please note that the following example only represents a starting point for operating
with a wind generator.

• <UpvStart> is set to the lowest possible value:
This achieves an early switch-on of the Windy Boy.

• <UdcWindStart> is set to the same value of <UpvStart>:
This achieves an early mains grid feed-in. If the wind turbine does not properly
start, or the inverter frequently switches on and off, it is recommended that you
increase <UdcWindStart> in (e.g.) 10 V steps.

• <UdcWindMax> is initially set to approx. 10 % below the maximum MPP voltage
of the Windy Boy:
In this case the slope of the ramp function is relatively flat. The maximum output
power is this only reached with a relatively high DC input voltage, which avoids
"braking" of the wind generator through excessive power consumption. This set­ting is especially suitable in locations with little or weak wind. Once the properties
of the wind generator are known, then the reduction of the <UdcWindMax> pa­rameter may be necessary, in order to extract the maximum power from the wind
generator even at low DC input voltages (low wind speeds). The ramp function
will then be steeper.

Contact the manufacturer of your wind generator for the typical properties of
your generator (voltage/power characteristic).

• <T-Stop> is set to the maximum value:
Here, the inverter remains connected to the mains grid, even at low DC input vol­tage levels, and "waits" for the next gust of wind. This delays an early switch-off
of the inverter.

• <T-Start> is set to the minimum value:
This achieves a reduction of the switch-on time (please observe the regulations of
the energy supplier responsible).

Only change the operating parameters when you know exactly what you are
doing!

SMA Technologie AG Maintenance and care

6 Maintenance and care

Because the Windy Boy can be used outdoors in places that are difficult to access,
the Windy Boy has been constructed for low maintenance. To guarantee safe oper­ation, it is usually adequate to check the device visually for damage approximately
every two months. It should also be checked if the red LED is illuminated and, if nec­essary, remove the fault by referring to chapter 3.3.4 "Description of the operational
status” (page 19).

In the interests of maximum yield, the operator should check, weekly if possible, un­der various conditions of wind, if the display of the Windy Boy indicates plausible
normal operation (cf. chapter 3.3.4 "Description of the operational status”
(page 19)). Naturally, this information can be obtained by using one of the commu­nication options.

Cleaning of the Windy Boy is only necessary when the heat dissipation is limited by
dirty cooling fins or a dirty space between the Windy Boy and the wall. The dirt
should be carefully removed with an appropriate soft brush or paintbrush.

If the LEDs are so dirty that they can no longer be seen, then they can be cleaned
with a damp cloth. Solvents, abrasives or corrosive liquids must not be used!

7 Expansions

As with all inverters in the Sunny Boy family, the Windy Boy can also be expanded
with a range of communication interfaces. This provides the operator with the possi­bility of requesting detailed operational data and error messages, for subsequent
analysis on a PC using (e.g.) the free software available from SMA.

The data can currently be transferred in five different ways:

• using Powerline

• using a separate RS485 cable

• using a separate RS232 cable

• using a wireless link (Sunny Beam)

• using a USB-Service-Interface (USBPBS)

The wind turbine can be monitored by the Windy Boy in a number of different ways.
SMA offers a range of products for this purpose, allowing you to install a tailor-made
monitoring system for your system. If you require detailed information about the Win­dy Boy products, please request the Sunny Family catalogue or visit www.SMA.de.
In the following sections the currently available communications options are schemati­cally described.

7.1 Sunny Data

Sunny Data is a PC program for direct monitoring of
your system. The connection of the Sunny Boys or the
Sunny Mini Centrals with the PC is described in the fol­lowing sections.

9 General information

9.1 Measurement channels and messages

If your Windy Boy is equipped with a communication component, then numerous
measurement channels and messages can be consulted. These can be useful for both
performance improvement and for fault prevention.

The following abbreviations apply:

BFR: Operation control unit

SRR: Current control unit

E-total Total amount of feed-in energy
Fac Grid frequency
Faults Fault type display under "Disturbance" status
h-total Total hours of mains supply feed-in operation
Iac-Ist Grid current

Ipv DC current
Netz-Ein Total number of mains supply switch-ons
Pac Mains supply performance provided
Riso Insulation resistance of the system to the mains supply connection
Seriennummer Serial number of the Windy Boy
Status Display of the current operational status
Uac Grid voltage
Upv-Ist DC input voltage
Upv-Soll Nominal DC voltage
Zac Mains supply impedance

The measurement channels provide information in German (e.g."Fehler“), or in
English (e.g. "Error“), depending on which software you are using (Sunny Data
or Sunny Data Control).

Operating instructions WB11_17-11:FE4205 Page 53

9.1.1 Status messages

The Windy Boy produces a range of status messages, depending on the mode in
which it is currently operating. The status messages can vary, depending on the type
of communication system you are using.

sary yield losses, the configuration and string size should be
checked. Check if the Windy Boy can be located in a better posi­tion with better ventilation, thus providing better heat dissipation.

The Windy Boy is operating in MPP mode. The Windy Boy takes
the highest possible performance from the PV generator. MPP is
the standard display when operating with normal sunshine (PV
operation only).

The Windy Boy is in Island Mode. This mode is specially con­ceived for operation in a stand alone power system with a Sunny
Island as network controller. More information about this topic
can be obtained from the Sunny Island operating manual under
the category "Droop Mode".

Testing the mains supply status (mains impedance), relay tests etc.
This message appears during the startup phase, before the Windy
Boy is connected to the mains supply. This message mainly ap­pears when there is little or no wind.

Fault (see table "Fault messages")
This fault occurs for reasons of safety and prevents the Windy Boy
from connecting to the mains network. This mode can also be man­ually set.

Interruption of operation after a fault. This status can also be man­ually set.

The changes in mains impedance exceed the permissible range
("Bfr" or "Srr" is an internal message that has no meaning for the us­er).

The Windy Boy disconnects from the mains grid or stand-alone grid,
to avoid potential damage. If possible, check the mains impedance
and check how often major deviations occur. If repeated variations
occur and this is causing "dZac-Bfr" or "dZac-Srr" faults, ask the elec­tricity provider if they agree to a modification of the operating pa­rameters. Discuss the proposed parameters with the SMA hotline.

A data transfer fault occurred during reading or writing of data from
the EEPROM, the data is not relevant for safe operation - this fault
has no effect on performance.

Data EEPROM is defective, the device has switched itself off because
the loss of important functions has disabled the Windy Boy. Contact
SMA.

One of the duplicate data sets in the EEPROM is defective and has
been reconstructed without loss of data.

The mains frequency has exceeded the permissible range ("Bfr" or
"Srr" is an internal message that has no meaning for the user). The
Windy Boy disconnects from the mains grid or stand-alone grid, to
avoid potential damage. Check the mains frequency and mains con­nections on the Windy Boy. If the mains frequency lies outside the
permissible range because of local conditions, ask the electricity pro­vider if they agree to a modification of the operating parameters.

If the mains frequency lies within an acceptable range and "Fac-Bfr"
or "Fac-Srr" faults are still being displayed, please contact the SMA
hotline.

Overcurrent on the AC side. This fault code is displayed if the current

Imax

in the AC network is larger than specified. Check your system config­uration and the mains supply conditions.

on the DC input is defective as a result of overvoltage. Consult

trained electrical personnel to correct the fault. You can find Instruc-

tions on how to change the varistors in the "Installation manual".

ROM

The Windy Boy firmware is faulty. Contact SMA if this fault occurs

frequently.

The mains voltage has exceeded the permissible range ("Bfr" or "Srr"

is an internal message that has no meaning for the user). The Uac

fault can have the following causes:

• Mains supply disconnected (circuit breaker or fuse)

• Broken AC cable or

Uac-Bfr /
Vac-Bfr

Uac-Srr /
Vac-Srr

• AC cable has a high internal resistance

For reasons of safety, the Windy Boy disconnects itself from the

mains network. Check the mains voltage and mains connections on

the Windy Boy. If the mains voltage lies outside the acceptable

range because of local conditions, ask the electricity provider if the

voltage can be adjusted at the feed-in point or if they agree to chang-

es in the values of the monitored operational limits.

If the mains voltage lies within an acceptable range and "Uac-Bfr" or

"Uac-Srr" faults are still being displayed, please contact the SMA

hotline.

Immediately disconnect the DC input of the Windy Boy. Otherwise

the Windy Boy could be severely damaged! Check the configuration

of your system and measure the DC voltage before reconnecting the

Windy Boy to the DC voltage.

General information SMA Technologie AG

Fault code Description

The mains impedance has exceeded the permissible range ("Bfr“ or

"Srr“ is an internal message that has no meaning for the user). The

Windy Boy disconnects from the mains grid or stand-alone grid, to

avoid potential damage. The impedance is calculated from the mains

supply impedance and the impedance of the mains connection cable
Zac-Bfr/

Zac-Srr

(AC cable) of the Windy Boy.

Check the mains voltage and mains connections on the Windy Boy.

Use a mains connection cable with an adequate cross section (= low

impedance), and observe the advice to this effect in the installation

instructions in chapter 4.3. If the mains impedance is still too high,

then ask the electricity provider if the characteristics of the mains sup-

ply at the feed-in point can be altered.
