2 Safety
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 unit. 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).
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 Precautions
DANGER!
Danger to life due to high voltages in the Sunny Boy!
• All work on the Sunny Boy must be carried out exclusively by qualified personnel.
CAUTION!
Danger of burn injuries due to hot housing parts!
• Do not touch the housing 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 degree IP21. The Sunny Boy is then no longer protected against water and
contamination with dirt!
If the device has been temporarily decommissioned, proceed as follows to restore the IP65
protection rating:
• 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 connecting and grounding the generator frame and
other electricity conducting surfaces in such a way that there is continuous conduction and
grounding in order to achieve maximum protection for systems and persons.

4 Mounting
4.1 Selecting the Mounting Location
Take the following conditions into account during mounting
• The mounting location and mounting method must be suitable for the weight and dimensions
(see section11 „Technical Data“ (39)) of the Sunny Boy.
• Mount on a solid surface.
• The mounting location must be accessible at all times.
• The Sunny Boy must be easy to remove from the mounting location at any time.
• The ambient temperature should be below +40 °C to guarantee optimal operation.
• 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.
DANGER!
Danger to life due to fire or explosion!
Despite careful construction, a fire can occur with electrical devices.
Do not install the Sunny Boy
• on flammable construction materials,
• in areas where highly flammable materials are stored,
• in potentially explosive areas!
CAUTION!
Danger of burn injuries due to hot housing parts!
• 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 Sunny Boy's weight of 25 kg into account for mounting.
