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.

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 instructionsWB11_17-11:FE4205Page 13
Unit descriptionSMA 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!

3.3 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.

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 instructionsWB11_17-11:FE4205Page 17
Unit descriptionSMA 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
illuminates 4 times
LED on
LED off
3s1s1s1s 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.

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).
