2.1 Intended Use
The Windy Boy is a wind power inverter, which converts rectified current of a small wind turbine
system into AC current and feeds this energy into the power distribution grid, domestic grid or the
Sunny Island system.
Principle of a small wind turbine system with Windy Boy
Furthermore, the Windy Boy can be used as an inverter for power conversion units based on
permanent magnet generators (hydro power systems, combined heat and power plant, diesel
generator, etc.). The manufacturer of the small wind turbine system or generator must have approved
his plant for operation with this Windy Boy.
When designing the PV plant, ensure that the permitted operating range of all components is
maintained at all times. In addition, ensure that through the use of appropriate protective measures
the maximum permissible input voltage of the inverter is not exceeded. SMA Solar Technology AG
offers you the corresponding components, such as the Windy Boy Protection Box
(overvoltage protection for wind power inverters including the rectifier).

Load Disconnection Unit
You must install a separate miniature circuit-breaker for each inverter in order to ensure that the
inverter can be securely disconnected under load. The maximum permissible fuse protection can be
found in Section 11"Technical Data" (page76).
Detailed information and examples on the design of miniature circuit-breakers are available in the
Technical Information "Miniature circuit-breaker" to be found in the download area of
SMA Solar Technology AG at www.SMA.de/en.
DANGER!
Danger to life due to fire
In the event of parallel connection of more than one inverter to the same miniature
circuit-breaker, the protective function of the miniature circuit-breaker is no longer
guaranteed. It can result in a cable fire or destruction of the inverter.
• Never connect several inverters to the same miniature circuit-breaker.
• Observe the maximum permissible fuse protection of the inverter when selecting the
miniature circuit-breaker.
DANGER!
Danger to life through electric shock
When a generator (inverter) and a load are connected to the same miniature circuitbreaker, the protective function of the miniature circuit-breaker is no longer guaranteed.
The currents from the inverter and the grid can accumulate to form overcurrents that are not
detected by the miniature circuit-breaker.
• Never connect the load between the
inverter and the miniature circuit-breaker
without protection.
• Always protect the load separately.
NOTICE!
Damage to the inverter due to the use of screw-type fuses as load disconnection
units
A screw-type fuse, e.g., DIAZED fuse or NEOZED fuse, is not a switch-disconnector and
must never be used as such. A screw-type fuse only acts as cable protection.
Disconnection under load using a screw-type fuse can damage the inverter.
• Use o nly a switch-di sconnecto r or a mi niature circui t-breaker as a l oad dis conne ction
unit.

5.5 Connection of the SMA Power Balancer
The inverter is standardly equipped with the SMA Power Balancer. This enables a circuitry of
3 inverters to a three-phase feed-in system.
Each of the three inverters in a group must be connected to a different line conductor of the
low-voltage grid (L1, L2, L3)!
If this electronic circuit is activated, you can specify how the other two inverters should react if there
is a device fault in the third inverter or a line voltage fault occurs in its phase.
The connections for the SMA Power Balancer are galvanically isolated from the rest of the inverter
electronic circuit.
5.5.1 Configuration
With configured country standard VDE-AR-N4105-MP or VDE-AR-N4105-HP, in the WB 5000A-11
and WB 6000A-11, the default setting of the SMA Power Balancer is activated and set to the
operation mode "PowerGuard". With all other country standards, the default setting of the
SMA Power Balancer in WB 5000A-11 und WB 6000A-11 is deactivated.
In WB 5000A/WB 5000A-IT/WB 6000A/WB 6000A-IT, the default setting of the
SMA Power Balancer is always deactivated, regardless of the configured country standard.
The SMA Power Balancer can be activated and configured via a communication product. To change
the "PowerBalancer" parameter, you need a personal access code, the so-called SMA Grid Guard
code. The application form for the personal access code is available in the download area at
www.SMA.de/en, in the "Certificate" category of the respective inverter.

6.3 Self-test in Accordance with DK 5940, Ed. 2.2 (Applies to Italy Only)
6.3.1 Starting the Self-Test by Tapping
You can start the test of the disconnection times by tapping on the enclosure lid. The requirement for
this is that the country configuration of the inverter has been set to Italy ("IT/DK5940 ") or "trimmed".
Proceed as follows for checking the disconnection times:
1. Connect the small wind turbine system to the inverter. The inverter can only initialize once the
small wind turbine system is producing enough power. It is therefore not possible to test the
disconnection time if there is no wind.
2. Connect the inverter on the AC side. To do this, you must execute the AC connection
(AC plug or direct connection) and/or switch on the miniature circuit-breaker on the grid supply
line (fuse and circuit-breaker).
3. The inverter is now in the startup phase, i.e. all 3 LEDs are simultaneously lit.
Start the self-test immediately after all 3 LEDS have gone out by tapping on the display of the
inverter.
4. The display will ask whether you would like to start
the test sequence. Confirm by tapping on the
display again within 30 seconds.
Once you have started the test sequence, the inverter will consecutively check the disconnection times
for overvoltage, undervoltage, maximum frequency and minimum frequency. During the test, the
inverter will display the values described in Section 6.3.2"Completion of the Self-test" (page51).
50 WB5A_6A-IA-IEN114540 Installation Manual
SMA Solar Technology AG Commissioning
6.3.2 Completion of the Self-test
Note the values which are displayed during the self-test. These values must be entered in a test report.
The results of each test test are displayed 3 times, one after the other. The respective message is
displayed for 10 seconds.
In the self-test, the upper and lower disconnection thresholds for each protective function are adjusted
on a linear basis with a variation of 0.05 Hz/s and 0.05 Vn/s for frequency and voltage monitoring.
As soon as the actual measured value goes outside the permitted range
(adjusted disconnection threshold), the inverter disconnects from the power distribution grid.
Thus, the inverter determines the reaction time and performs the self-test.
Overvoltage Test
The inverter begins with the overvoltage test. During the
test sequence, the voltage limit applied is shown in the
display of the inverter.
The voltage is reduced step by step until the
disconnection threshold is reached and the inverter
disconnects from the power distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
the following values:
•Disconnection value,
•Calibration value,
•Reaction time,
• Current line voltage.
Installation Manual WB5A_6A-IA-IEN114540 51
Commissioning SMA Solar Technology AG
Undervoltage Test
After the overvoltage test, the inverter proceeds to carry
out the undervoltage test. During the test sequence, the
current calibration value of the voltage limit applied is
shown in the display of the inverter.
The voltage is increased step by step until the
disconnection threshold is reached and the inverter
disconnects from the power distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
the following values:
•Disconnection value,
•Calibration value,
•Reaction time,
• Current line voltage.

Maximum Frequency
In a third step, the inverter tests the maximum frequency.
During the test sequence, the frequency limit applied is
shown in the display of the inverter.
The frequency is reduced step by step until the
disconnection threshold is reached and the inverter
disconnects from the power distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
the following values:
•Disconnection value,
•Calibration value,
•Reaction time,
• Current power frequency
Installation Manual WB5A_6A-IA-IEN114540 53
Commissioning SMA Solar Technology AG
Minimum Frequency
In the last step, the inverter tests the minimum frequency.
During the test sequence, the frequency limit applied is
shown in the display of the inverter.
The frequency is increased step by step until the
disconnection threshold is reached and the inverter
disconnects from the power distribution grid.
Once the inverter has disconnected from the power
distribution grid, the display successively shows the following values:
•Disconnection value,
•Calibration value,
•Reaction time,
• Current power frequency
When the inverter has carried out all four tests, it switches to the "Turbine" operating mode. The
original calibration values are then reset and the inverter automatically connects to the power
distribution grid. If you wish to repeat the test, you must switch off the inverter, i.e. disconnect it on the
AC and DC sides, and then recommission. You can then restart the self-test as described in Section
6.3.1"Starting the Self-Test by Tapping" (page50). The inverter recommences the test sequence as
described in Section 6.3.2"Completion of the Self-test" (page51).

6.4 Operating States of the Inverter
Startup Procedure
If the inverter has enough voltage and power, the three LEDs on the inverter light up simultaneously,
indicating that the startup process is ongoing.
As soon as the DC input voltage reaches the value configured for the parameter "Vpv-Start", the
inverter trips several self-tests, measuring procedures and synchronization with the power distribution
grid. This operating state is indicated on the inverter by the flashing green LED.
Once the DC input voltage has reached the "Vpv-Start" value for the time configured in "T-Start" and
all the tests have been completed successfully, the inverter connects to the power distribution grid and
the green LED comes on permanently. T he i nve rte r th en s wit ches to characteristic curve operation, and
regulates the input current according to the generator voltage.
Characteristic Curve Operation
After the startup procedure, the inverter switches to characteristic curve operation and regulates the
input current according to the generator voltage.
The inverter then begins to exert a load on the small wind turbine system, draws power from the small
wind turbine system according to the input voltage present, and then feeds it into the power
distribution grid. The maximum power output corresponds to the maximum AC power of the inverter.
However, it can be reduced using the "Pmax" parameter.
Shutdown Procedure
If wind strength is so low that the DC input voltage falls below an internally calculated value, the
inverter stops feeding power to the power distribution grid for the period defined in "T-Stop". As soon
as DC input voltage increases again, the inverter switches back to characteristic curve operation.
If the DC input voltage remains below an internally calculated value for the time set in "T-Stop", the
inverter will switch off.
If the DC input voltage is no longer sufficient to supply the on-board electronics with power, the
inverter switches off immediately.

9.3 Red LED Permanently On
If the red LED of the status display is continuously on during operation, there is either a ground fault
in the system or at least one of the varistors for the overvoltage protection is defective.
In deliberately grounded small wind turbine systems, the red LED has been on ever since the inverter
was commissioned. However, this has no impact on the function of the inverter. Before you check the
small wind turbine system for a ground fault, check whether deliberate grounding has been carried
out.
In deliberately grounded small wind turbine systems, check every so often that the varistors in the
inverter are working properly, since a varistor fault can no longer be displayed.
9.3.1 Checking the Small Wind Turbine System for a Ground Fault
DANGER!
Risk of lethal electric shock
• Do not touch the small wind turbine system
• Only touch the insulation of the cables on the small wind turbine system.
• Do not touch PE.
1. Disconnect the inverter on both the DC and AC sides as described in Section 7.2"Opening the
Inverter" (page57).
2. Measure resistances between the phases and the ground potential:
– Measure resistance between L1 of the small wind turbine system and the ground potential,
and record value.
– Measure resistance between L2 of the small wind turbine system and the ground potential,
and record value.
– Measure resistance between L3 of the small wind turbine system and the ground potential,
and record value.
If the measured resistances are smaller than 10 Ω , there is a ground fault present in the small
wind turbine system. Eliminate the ground fault.
If the measured resistances tend towards infinity, there is no ground fault present in the small
wind turbine system and presumably the varistors are faulty.
– Check the function of the varistors as described in Section 9.3.2"Checking the Function of
the Varistors" (page72).
Installation Manual WB5A_6A-IA-IEN114540 71
Troubleshooting SMA Solar Technology AG
9.3.2 Checking the Function of the Varistors
Varistors are wear parts. Their functional efficiency diminishes with age or repeated strain as a result
of overvoltage. It is therefore possible that one of the thermally monitored varistors has lost its
protective function.
Position of varistors
The position of the varistors can be determined with the help of the diagram below.
Observe the following assignment of the terminals:
• Terminal A: outer terminal with loop
(varistor connection with crimp)
• Terminal B: middle terminal
• Terminal C: outer terminal with loop
(varistor connection without crimp)
You can check the function of the varistors as follows:
1. Open the inverter as described in Section 7.2"Opening the Inverter" (page57).
2. Use a multimeter to check that all the installed
varistors have a conductive connection between
connectors B and C.
Result Measure
There is a conductive connection. There must be a different error in the inverter.
•Close the inverter as described in
Section 7.3"Closing the Inverter" (page59).
• Contact the SMA Service Line.
72 WB5A_6A-IA-IEN114540 Installation Manual
SMA Solar Technology AG Troubleshooting
Result Measure
There is no conductive connection.
The respective varistor is defective and must be
replaced.
Varistor failure is generally due to influences that affect
all varistors in a similar manner (temperature, age,
induced overvoltage). SMA Solar Technology AG
recommends that you replace both varistors.
The varistors are specially manufactured for use in the
inverter and are not commercially available. You must
order replacement varistors directly from
SMA Solar Technology AG
(see Section 12"Accessories" (page83)).
• To replace the varistors, proceed to step 3.
NOTICE!
Destruction of the inverter as a result of defective varistors.
• Provide for replacement varistors immediately and replace the defective varistors.
• For systems with a high risk of overvoltage, do not operate inverters using faulty
varistors or no varistors at all.
3. Insert insertion tool into the openings of the terminal
contacts (1).
☑ This releases the terminals.
If you have not received an insertion tool for
operating the terminals together with the
replacement varistors, please contact
SMA Solar Technology AG. As an alternative, the
terminal contacts can be operated using a 3.5 mm
screwdriver.
4. Remove the varistor (2).
5. Insert the new varistor (3).
When reinstalling, the pole with the small loop
(crimp) must be mounted in terminal A (3).
6. Close the inverter as described in
Section 7.3"Closing the Inverter" (page59).
☑ Testing and replacement of the varistors is complete.
