SMA Technology AG Introduction

1 Introduction

The installation of the Windy Boy 5000 / 6000 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 grid­connected 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 supply.

To this end, the Windy Boy converts the direct current (DC) from permanent-magnet
wind turbines, which vary with speed, into grid-compatible alternating current (AC).
The Windy Boy requires the constant presence of mains supply voltage!

The Windy Boy 5000 / 6000 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 5000 / 6000 conforms to the
electromagnetic tolerance regulations and the low-voltage regulations of the relevant
combined European norms, as confirmed in the CE conformity declaration (10.3
"Declaration of conformity (CE)” (page 63)).

The documentation provided here covers all such topics that are of interest when
operating Windy Boy 5000 / 6000 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 commission of the Windy Boy 5000 /
6000 should be taken from the installation instructions delivered with the device. The
Windy Boy 5000 / 6000 inverter has a special operational 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.

Windy Boy

Public Mains Grid

Many wind turbine manufacturers offer an extra over-voltage protection module.
These components prevent the destruction of the downstream Windy Boy 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 Windy
Boy is disconnected from the mains supply 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 Windy Boy 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.

Operating instructions WB50_60-11:FE4105 Page 13

Unit description SMA Technology AG

In grid-connected systems, we recommend the use of one of the electronic protection
mechanisms described here. Please note that overvoltage on the Windy Boy 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 Windy Boy is only exceeded for a
short time.

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 5000 / 6000 leads to loss of the right to all warranty
claims.

In case of overvoltage, immediately disconnect the DC input of the
Windy Boy 5000 / 6000! The presence of excessive input voltage
can lead to irreparable damage!

When the Windy Boy 5000 / 6000 receives an excessive DC input voltage, it
automatically disconnects from the mains supply and no longer feeds power
into the grid. When the Windy Boy 5000 / 6000 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 5000 / 6000!

3.3 Operating modes

The operational status is displayed using three light-emitting diodes (LEDs) in the
cover of the Windy Boy 5000 / 6000. To allow the device to signal its operational
status via the integrated LEDs, the Windy Boy 5000 / 6000 must be connected to the
DC side of the system. There must be enough wind energy present, so that the Windy
Boy 5000 / 6000 has adequate DC voltage.

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 5000 / 6000 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 WB50_60-11:FE4105 Page 17

Unit description SMA Technology 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
illuminates 4 times

LED on

LED off

3s 1s1s 1s 1s

5s

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
5000 / 6000.

12

34

When the Windy Boy 5000 / 6000 receives an excessive DC input voltage, it
automatically disconnects from the mains supply and no longer feeds power
into the grid. When the Windy Boy 5000 / 6000 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 5000 / 6000!

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 communications options detailed in
chapter 8 "Expansions” (page 41).

successfully passed the measurement
electronics and SMA grid guard self-tests
and has begun feed-in operation.

The Windy Boy 5000 / 6000 is working
normally and is feeding electricity into

The Windy Boy 5000 / 6000 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 5000 / 6000 is intact.

If one of these faults can be found, then the mains supply
connection of the Windy Boy 5000 / 6000 must be checked by
qualified electrical personnel.

SMA Technology AG Maintenance and care

5 Maintenance and care

Because the Windy Boy 5000 / 6000 can be used outdoors in places that are difficult
to access, it has been constructed for low maintenance.

In the interests of maximum yield, the operator should check, weekly if possible,
under various conditions of wind, if the displays of the Windy Boy 5000 / 6000
indicate plausible normal operation (cf. chapter 3.3.4 "Description of the operational
status" (page19)). Naturally, this information can be obtained by using one of the
communications options.

The cleaning intervals are dependent from the ambient conditions. Make sure that
enough air can flow through the fan guards. With that you can contribute to an
optimum yield of your system.

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!

A detailed description of how to clean the fans can be found in the installation
manual of the Windy Boy 5000 / 6000.

SMA Technology AG Turbine operation

6 Turbine operation

6.1 Overview

The Windy Boy 5000 / 6000 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
supply.

The Windy Boy 5000 / 6000 is externally identical to the Sunny Mini Central inverter
for photovoltaic systems.

The Windy Boy 5000 / 6000 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 Windy Boy 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.

6.2 Characteristic curve function

The "Turbine" operating mode of the Windy Boy 5000 / 6000 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 5000 / 6000 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.

Operating instructions WB50_60-11:FE4105 Page 33

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 5000 / 6000 (factory settings) are shown in
the following table.

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 6.4
"General setting example” (page 37).

To perform the configuration process, the DC input voltage must be greater
than <UpvStart> and the Windy Boy 5000 / 6000 must be connected to the
mains supply.

Operating instructions WB50_60-11:FE4105 Page 35

Turbine operation SMA Technology AG

6.3 Characteristic curve operation in "Turbine"

operating mode

Please note: The linear characteristic curve of the Windy Boy 5000 / 6000 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
Windy Boy begins a number of self tests, measurement processes and synchronizes
with the mains supply. If the self tests are successfully completed, and the DC input
voltage remains above the value defined in <UpvStart> for the time defined in <T­Start>, the Windy Boy connects to the mains supply.

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

As soon as the DC input voltage reaches the value defined in the parameter
<UdcWindMax>, the Windy Boy 5000 / 6000 feeds the mains supply with the
maximum possible power. If the input voltage continues to rise, the Windy Boy 5000
/ 6000 continues to feed the mains supply at maximum power.

The characteristic curve ends at the maximum permissible input voltage of the Windy
Boy 5000 / 6000, which must never be exceeded.

If the wind strength is so low that the DC input voltage falls below <UpvStart>, then
the Windy Boy ceases feeding power into the mains supply for the period defined in
<T-Stop>.

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 <Vmin>, then there is insufficient energy for the on-board electronics and the
Windy Boy will switch off.

If the DC input voltage lies between <Vmin> and <UpvStart> for the time defined by
<T-Stop>, then the Windy Boy 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 36 WB50_60-11:FE4105 Operating instructions

SMA Technology AG Turbine operation

6.4 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 5000 / 6000.

• <UdcWindStart> is set to the same value of <UpvStart>:
This achieves an early mains supply feed-in. If the wind turbine does not properly
start, or the Windy Boy frequently switches on and off, i t is rec ommended 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 5000 / 6000:
In this case the slope of the ramp function is relatively flat. The maximum output
power is 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 Windy Boy remains connected to the mains supply, even at low DC
input voltage levels, and "waits" for the next gust of wind. This delays an early
switch-off of the Windy Boy.

• <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!

7 Maintenance and care

Because the Windy Boy 5000 / 6000 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 solar irradiation, if the displays of the Windy Boy 5000 /
6000 indicate 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 communications 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!

the mode in which it is currently operating. The status messages can vary, depending
on the type of communications system you are using.

Derating Overtemperature in inverter ("WR"). The Windy Boy 5000 /

6000 reduces its performance to avoid overheating the device. To
avoid unnecessary yield losses, the configuration and string size
should be checked. Check if the Windy Boy 5000 / 6000 can be
located in a better position with better ventilation, thus providing
better heat dissipation.

Mpp The Windy Boy 5000 / 6000 is operating in MPP mode. The

Windy Boy 5000 / 6000 takes the highest possible performance
from the PV generator. MPP is the standard display when

mains impedance and check how often major deviations occur. If
repeated variations occur and this is causing "dZac-Bfr" or "dZac­Srr" faults, ask the electricity provider if they agree to a modification
of the operating parameters. Discuss the proposed parameters with
