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.
