2.1 Appropriate Usage
The Sunny Boy is a PV inverter, which converts the DC current of a PV generator to AC current and
feeds it into the public grid.
Principle of a solar 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 solar modules to the Sunny Boy.
When planning 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/SunnyDesign)
will assist you in this. 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 Application
Note 2 "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 operating license.
