2.1 Appropriate Usage
The Sunny Boy is a solar inverter that converts the DC current of the PV array into an AC current and
feeds it into the grid.
Refer to the inverter installation guide for detailed information about the product and its intended use.
The limit values specified in the installation guide of the respective inverter must be strictly adhered to.
The inverter may only be operated with PV arrays (modules and cabling) that have protective
insulation. Do not connect any power sources 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.
Contact the SMA Serviceline if you need clarification regarding proper use of the inverter.
Principle of the string inverter
The string inverter connects solar modules that are connected in series (strings) to the power
distribution grid. Thus, even large PV arrays can be set up using multiple individual strings, each
having its own respective string inverter.
