2.1 Appropriate Usage
The Sunny Boy is a PV inverter which converts the direct current of a PV generator into alternating
current and feeds this into the public grid.
Principle of a PV plant with this Sunny Boy
The Sunny Boy must 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 device. 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 SMA Solar Technology AG void the warranty claims and operation permission.
