2.1 Intended Use
The Sunny Boy is a PV inverter which converts the DC current of the PV array to AC current and feeds
it into the power distribution grid.
Principle of a PV plant with this Sunny Boy device
The Sunny Boy may only be operated with PV arrays (PV 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 plant, 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 PV 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 component parts not expressly recommended or
sold by SMA Solar Technology AG shall void any warranty claims and the operation permission.
