The inverter is operating in backup power mode. The contactors K1 and K2 to
the public grid are open.

The Fronius Smart Meter monitors the grid parameters on the public grid
and passes this information to the inverter.
The stability of the returned public grid is determined by checking the meas-
ured values of the Fronius Smart Meter.
On the basis of adjustments that have been carried out, the inverter ends
backup power mode and disconnects the outputs.
The inverter deactivates K3. Power is restored to contactors K1, K2, K4 and
K5.
All circuits are reconnected to the public grid and are supplied by the grid.
The inverter does not feed anything into the grid at this time.
The inverter can start feeding energy into the grid again after performing the
grid checks required by the relevant standard.
