2 Security
2.1 Appropriate Usage
The Sunny Boy is a PV inverter, which converts the DC current of the PV generator to AC current and
feeds it into the public grid.
Principle of a PV system with this Sunny Boy
The Sunny Boy may only be operated with PV generators (modules and cabling) of protection
class II. Do not connect any sources of energy other than PV modules to the Sunny Boy.
When designing the PV system, ensure that the values comply with the permitted operating range of
all components at all times. The free design program "Sunny Design"
(www.SMA.de/en/SunnyDesign) will assist you. The manufacturer of the PV modules must have
approved the modules for use with this Sunny Boy. You must also ensure that all measures
recommended by the module manufacturer for long-term maintenance of the module properties are
taken (see also Technical Information "Module Technology", in the download area of
www.SMA.de/en).
Do not use the Sunny Boy for purposes other than those described here. Alternative uses,
modifications to the Sunny Boy or the installation of components not expressly recommended or sold
by the manufacturer void the warranty claims and operation permission.

2.2 Safety Instructions
DANGER!
Danger to life due to high voltages in the Sunny Boy!
• All work on the Sunny Boy must only be carried out by qualified personnel.
CAUTION!
Parts of the enclosure can get hot - Risk of burn injuries!
• Do not touch the enclosure of the Sunny Boy during operation.
NOTICE!
Foreign objects or water entering the Sunny Boy can damage the device!
Once the Electronic Solar Switch has been pulled out, the Sunny Boy only provides
protection rating IP21. The Sunny Boy is then no longer protected against water and
contamination with dirt!
In order that the protection rating IP65 is also provided during a temporary
decommissioning, proceed as follows:
• Unplug all DC plug connectors and seal them with the protecting caps provided.
• Attach the Electronic Solar Switch again.
Grounding the PV generator
Comply with the local requirements for grounding the modules and the PV generator. SMA
Solar Technology recommends to electrically bond the module frames, the racks and all
metal surfaces and ground these in order to have optimal protection of the system and
personnel.

4 Installing the Device
4.1 Selecting the Mounting Location
Observe the following conditions during mounting:
• The installation method and mounting location must be suitable for the weight and dimensions
of the Sunny Boy (see section 11 "Technical Data" (page42)).
• Mount on a solid surface.
• The installation location must be accessible at all times.
• Vertical installation or tilted backwards by max. 45°.
• The connection area must point downwards.
• Never install the device with a forward tilt.
• Do not install horizontally.
• Install at eye level to allow operating modes to be read.
DANGER!
Danger to life due to fire or explosion!
Despite careful construction, a fire can occur with electrical devices.
• Do not mount the Sunny Boy on flammable construction materials.
• Do not mount the Sunny Boy near highly flammable materials.
• Do not mount the Sunny Boy in potentially explosive areas.
CAUTION!
Parts of the enclosure can get hot - Risk of burn injuries!
• Mount the Sunny Boy in such a way that it cannot be touched inadvertently during
operation.
CAUTION!
Risk of injury due to the heavy weight of the Sunny Boy!
• Take the weight of the Sunny Boy of approx. 25 kg into account for mounting.

Installing the Device SMA Solar Technology AG
12 SB11_12_17-IEN094131 Installation Guide
• The ambient temperature should be below 40 °C to ensure optimal operation.
• The Sunny Boy must be easy to remove from the mounting location at any time.
• Do not expose the Sunny Boy to direct sunlight, so as to avoid power reduction due to excessive
heating.
• In a living area, do not mount the unit on
plasterboard walls (or similar) in order to avoid
audible vibrations.
The Sunny Boy can make noises when in use which
can be regarded as a nuisance when installed in a
living area.
• Observe the minimum clearances to walls, other
inverters or objects as shown in the diagram in
order to guarantee sufficient heat dissipation and to
have enough space for removing the Electronic
Solar Switch.

4.2 Mounting the Sunny Boy with a Wall Mounting Bracket
1. Use the wall mounting bracket as a drilling template and mark the position of the drill holes.
2. Attach the wall mounting bracket to the wall using
appropriate screws and washers.
CAUTION!
Risk of injury due to the heavy weight of the Sunny Boy!
• Take the weight of the Sunny Boy of approx. 25 kg into account.
• When mounting the bracket, use fastening material suitable for the material.

5.2 Connecting the Sunny Boy to the public grid (AC)
Cable Design
The conductor cross-section should be dimensioned in a way that output losses do not exceed 1% at
nominal power. Use "Sunny Design" (www.SMA.de/en/SunnyDesign) for this.
The maximum cable lengths relative to the conductor cross-section are shown in the following table.
The conductor cross-section required in individual cases depends on the following factors:
• ambient temperature,
•routing method,
•UV resistance,
• line losses,
• valid installation guidelines of the respective country (of the installation site).
Cable Requirements
Connection requirements of the grid operator
Comply with the connection requirements of your utility operator.

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 maximal permissible rating is located in
section 11 "Technical Data" (page42)
Detailed information and examples for the design of a line circuit breaker can be found in the
Technical Information "Line Circuit Breaker" in the download area of 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 a single line circuit breaker.
• Comply with the maximum permissible fuse protection of the inverter when selecting
the line circuit breaker.
NOTICE!
Damaging of the Sunny Boy by using screw type fuse elements as 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 Sunny Boy can be
damaged.
• Use only a load disconnecting switch or a line circuit breaker as load disconnecting
unit.
DANGER!
Danger to life due to fire!
When a generator (Sunny Boy) 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 Sunny Boy and the grid
can add up to overcurrent which is not
detected by the line circuit breaker.
• Never connect loads between the Sunny Boy and the line circuit breaker without
protection.
• Always install separate fuses for loads.
