4.3 Secure Power Supply Operation
4.3.1 Activating Secure Power Supply Operation
If an outlet and a switch for secure power supply operation are connected to the inverter, you can
supply a load with current from the PV system in case of a grid failure during the day. If you
activate the secure power supply operation, the inverter supplies loads that are connected to the
outlet for secure power supply operation.
In case of overload, underload or insufficient solar irradiation, the voltage supply of the outlet is
briefly interrupted. The inverter automatically attempts to reestablish the voltage supply 20 seconds
after the interruption. This can lead to inadvertent starting of the load that is connected to the outlet.
Ensure that the load connected to the outlet does not consume too much power. If necessary,
reduce the power consumption of the load.
In case of a grid failure during the night, secure power supply operation is not
possible
During the night, secure power supply operation cannot be activated since the PV system does
not produce power that is required to supply the load.
• In case of a grid failure during the night, do not activate secure power supply operation.
• Continue to operate the inverter on the utility grid and wait for restoration of grid
operation.
• In the event of a persistent grid failure, switch to secure power supply operation after
sunrise.
