4 System Description

This chapter describes the individual operation operating mode and functions of the equipment.

4.1Individual Operation

In individual operation, the inverter works independently and is not connected to any other inverters. The DC infeed from the PV cells and the link to the AC mains are only connected to this inverter.

Switching operations, control commands and modifications to set- ting parameters are only performed by the unit concerned.
