2 Safety
2.1 Appropriate Usage
The Windy Boy is a wind power inverter, which converts rectified cur ren t of a small w ind tur bin e system
into AC current and feeds this energy into the power distribution grid, domestic grid or the
SunnyIslandsystem.
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 the
permanent magnet generators (hydro power systems, combined heat and power plant,
dieselgenerator, etc.). The manufacturer of the small wind turbine system or the generators should
have his system set up for operation with the Windy Boy (see also the Windy Boy planning guidelines
in the download area at www.SMA.de/en).
SMA Solar Technology AG recommends to operate Windy Boy and a small wind turbine system
without neutral grounding.
When designing the system, ensure that the permitted operating range of all components is
maintained at all times. Also use appropriate protective measures to make sure that the maximum
permissible input voltage of the inverter is not exceeded. Use of the WBP-Box 500-11
WindyBoyProtection Box by SMA Solar Technology AG is obligatory.
Do not use the Windy Boy for purposes other than those described here. Alternative uses,
modifications to the Windy Boy or the installation of components not expressly recommended or sold
by SMA Solar Technology AG void the warranty claims and operation permission.

SMA Solar Technology AG Mounting
4.2 Selecting the Mounting Location
Consider the following points when selecting where to install:
• The mounting method and location must be suitable for the inverter's weight and dimensions
(see section 14”Technical Data” (page85)).
• Mount on a solid surface.
• The mounting location must at all times be clear and have safe access without the use of
additional aids such as scaffolding or lifting platforms. Any possible service actions are
otherwise limited.
• Vertical installation or tilted backwards by max. 15°.
• Never mount the device with a forward tilt.
• Do not mount horizontally.
• The connection area must point downward.
• Mount at eye level to allow operating status to be read at all times.
• To ensure optimal operation, the ambient temperature should be below 40°C.
• Do not expose the inverter to direct sunlight to avoid a power reduction due to excessive
heating.
• I n a l ivi ng a rea, do n ot m oun t th e unit on pla ste rbo ard wal ls (or si mil ar) in o rde r to avoid au dib le
vibrations. The inverter can make noises when in use, which may be perceived as a nuisance in
a living area.
Installation Guide WB36TL_50TL-IEN102011 15
Mounting SMA Solar Technology AG
• Observe the minimum clearances to walls, other
inverters or objects as shown in the diagram in
order to ensure sufficient heat dissipation and
sufficient space for the removal of the Electronic
Solar Switch.
Multiple inverters installed in areas with high ambient temperatures
There must be sufficient clearance between the individual inverters to ensure that inverters
are not subjected to dissipated air from adjacent devices.
If necessary, increase the clearances and make sure there is enough ventilation to ensure
sufficient cooling of the inverters.

5.1 Safety
WARNING!
Electric shock resulting from short circuit.
If cables with a different voltage are routed in parallel, there is the risk of a short circuit in
the event of damage to the cable insulation.
• Route all cables separately.
CAUTION!
Electrostatic discharges can damage the inverter.
Internal components of the inverter can be irreparably damaged by static discharge.
• Ground yourself before touching a component.

Electrical Connection SMA Solar Technology AG
5.3 Connection to the Power Distribution Grid (AC)
5.3.1 Conditions for the AC Connection
Observe all connection conditions of the utility operator for connecting to the power distribution grid!
Residual current breaker
The inverter is equipped with an integrated universal current sensitive residual-current monitoring unit.
The inverter can automatically differ between real fault currents and "normal" capacitive leakage
currents.
If an external RCD or residual current breaker is strictly required, you must use a switch that triggers
at a failure current of 100 mA or higher.
Cable Sizing
The grid impedance of the AC cable must not exceed 1 Ohm. Otherwise, the inverter will disconnect
at full feed capacity due to excessive voltage at the feed-in point.
The wire cross-section should be dimensioned so output losses do not exceed 1% at nominal power.
The maximum cable lengths depending on the wire diameter are displayed in the following table.
Cross section of insulated
conductor
6.0 mm² 23.3 m 18.6 m
10.0 mm² 38.8 m 31.1 m
The conductor cross-sectional area required in individual cases depends on the following factors,
among others:
• Ambient temperature,
•Routing method,
•UV resistance,
•Conduction losses,
• valid installation requirements of the respective country (installation location).

Load Disconnection Unit
You must install a separate line circuit breaker for each inverter in order to ensure that the inverter
can be securely disconnected under load. The maximum permissible rating is located in
section14”Technical Data” (page85).

Information "Line Circuit Breaker" in the SMA Solar Technology AG download area at
www.SMA.de/en.
DANGER!
Danger to life due to fire.
When more than one inverter is connected to the same line circuit breaker, the protective
function of the line circuit breaker is no longer guaranteed. It can result in a cable fire or
the destruction of the inverter.
• Never connect several inverters to the same line circuit breaker.
• Comply with the maximum permissible fuse protection of the inverter when selecting
the line circuit breaker.
Installation Guide WB36TL_50TL-IEN102011 27
Electrical Connection SMA Solar Technology AG
DANGER!
Risk of electric shock.
When a generator (inverter) and a consumer are connected to the same line circuit
breaker, the protective function of the line circuit breaker is no longer guaranteed. The
current from the inverter and the grid can accumulate to overcurrent, which is not detected
by the line circuit breaker.
• Never connect consumers between the
in verter and the li ne circuit breaker without
protection.
• Always protect consumers separately.
CAUTION!
Damage to the inverter by using screw type fuse elements as a load
disconnection unit.
A screw type fuse element, e.g. D system (Diazed) or D0 system (Neozed) is not a circuit
breaker, and may not be used as a load disconnection unit. A screw type fuse element is
only used as cable protection.
When disconnecting under load using a screw type fuse element, the inverter can be
