• Measuring and transferring the required parameters for energy management and Solar.web by the Fronius Smart Meter
• Disconnecting from the public grid to enable operation in emergency power mode if the grid parameters are outside the country-specific standards.
• Reconnecting to the public grid when the grid parameters are within the limits specified by the country-specific standards.
• Option of having a separate emergency power circuit or several emergency power circuits that are supplied even during failure of the public grid. The total load of the emergency power circuits must not exceed the nominal output of the inverter. Furthermore, the performance of the attached battery must also be considered. The other circuits are not supplied in the event of a power failure.

The use of contactor K2 is optional in Australia.

If not all the consumers in the home need to be supplied in an emergency power situation, the circuits need to be divided into emergency power circuits and non-emergency power circuits.
The total load of the emergency power circuits must not exceed the nominal output of the inverter.

The emergency power circuits and non-emergency power circuits must be fused separately according to the required safety measures (residual-current circuit breaker, automatic circuit breaker, etc.).
In emergency power mode, only the emergency power circuits are disconnected from the grid by contactors K1 and K2 3-pin. The rest of the home network is not supplied with power in this case

• The main contacts of contactors K1 and K2 must be installed between the Fronius Smart Meter and the residual-current circuit breaker of the inverter or the residual-current circuit breaker of the emergency power circuits.
• The supply voltage for contactors K1 and K2 is provided by the public grid and must be connected to phase 1 (L1) after the Fronius Smart Meter and fused accordingly.
• An NC contact for relay K3 interrupts the supply voltage to contactors K1 and K2. This prevents the emergency power network of the inverter from being switched to the public grid.
• The NO contact of relay K3 gives feedback to the inverter on whether the locking was successfully performed by relay K3.
• Additional inverters or other AC sources can be installed in the emergency power circuit after the main contacts of K1 and K2. The sources are not synchronised to the network of the Fronius Symo Hybrid because this emergency power network has a frequency of 53 Hz.

1. The public grid is monitored by the inverter's internal grid and system protection unit and by the Fronius Smart Meter connected to it.
2. Failure of the public grid
3. The inverter carries out the necessary measures according to the country standard and then switches off.
   Contactors K1 and K2 drop out. This disconnects the emergency power circuits and the inverter from the rest of the home network and from the public grid, as the main contacts of the contactors K1 and K2 3-pin open.The NC auxiliary contacts of contactors K1 and K2 send feedback to the inverter that the contactors are open (a condition for starting the emergency power mode).
4. The inverter activates relay K3, which interrupts the supply to contactors K1 and K2. This prevents unintentional activation of contactors K1 and K2 and thus a grid connection when voltage is restored in the grid.
5. The NO contact of relay K3 gives optional feedback to the inverter on whether the locking was successfully performed by relay K3.
6. Based on the feedback from the contactors and the measurements at the inverter terminals and at the Smart Meter, the inverter decides that emergency power mode can be started.
7. The inverter starts emergency power mode after a defined checking period
8. All loads in the emergency power circuits are supplied with power. The remaining loads are not supplied with power and are safely isolated.

1. The inverter is operating in emergency power mode. The contactors K1 and K2 to the public grid are open.
2. Public grid available again
3. The Fronius Smart Meter monitors the grid parameters on the public grid and passes this information to the inverter.
4. After a defined measuring period, the restored public grid is deemed to be stable.
5. The inverter ends emergency power mode and disconnects the outputs.
6. The inverter deactivates K3. The contactors K1 and K2 are reactivated.
7. All circuits are reconnected to the public grid and are supplied by the grid. The inverter, therefore, does not feed anything into the grid.
8. The inverter can start feeding energy into the grid again after performing the grid checks required by the country standard.

• The external grid and system protection unit must be installed after the Fronius Smart Meter. Precise installation and cabling notes for the external grid and system protection unit can be found in its separate Operating Instructions.
• The remote trip input of the external grid and system protection unit must be set to NC according to the manufacturer's Operating Instructions.
