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.
