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.
• T he a ppl iance i s no t to be u sed by c hildre n or per son s wi th r educed physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction.
• Children should be supervised to ensure that they do not play with the appliance.
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
Compl y with the local r equir ements for gro unding the mod ules a nd 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
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.
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" (page42)).
• 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.
Installation Guide SB11_12_17-IEN100132 11
Installing the Device SMA Solar Technology AG
• 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
or der to g uar ant ee suff ici ent heat di ssi pat ion and to
have enough space for removing the Electronic
Solar Switch.
