2 Safety
2.1 Appropriate usage
The Sunny Boy is a PV inverter which converts the DC current of the PV array to AC current and feeds
it into the grid.
More precise information on this subject and on your device can be found in the installation guide.
The operational limits specified in the installation guide for the particular inverter must be observed.
All inverters may only be operated with PV generators (modules and cabling) with protective
insulation. Do not connect any sources of energy other than PV modules to the inverter.
Do not use the inverter for purposes other than those described here. Alternative uses, modifications
to the inverter or the installation of components not expressly recommended or sold by the
manufacturer void the warranty claims and operating permission. If you have questions regarding the
proper usage of the inverters, contact the SMA Serviceline.
Principle of the string inverter
The string inverter is used to connect a number of series-connected PV modules (strings) to the public
supply grid. This way, even a large PV generator can be constructed from a large number of
individual strings, each having its own string inverter. The energy is then combined on the AC side.
