Content
Both in off-grid systems and in the event of grid failures in battery-backup systems, grid fluctuations in the stand-alone grid
are possible. This may cause severe deviations in nominal voltage and nominal frequency. Despite such fluctuations, all
of the components in these systems must function without problems.
This technical information will inform you about the following topics:
• Which PV inverters you can use in off-grid systems and battery-backup systems
• Which parameters you need to set in the PV inverter
• What type of communication you need to install in battery-backup systems
• Which values the parameters of PV inverters will take in stand-alone mode
• How the output power of the PV inverter can be limited by the Frequency-Shift Power Control (FSPC) function of the
