General General remarks The examples illustrated in this document (particularly cabling variants and circuit dia- grams) are suggestions only. These examples have been carefully developed and tested, and may therefore be used as the basis for an installation. Anyone following or using these examples does so at their own risk.
The following points regarding cabling must be considered: 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-cur- rent circuit breaker of the emergency power circuits.
Public grid available again energy into the The Fronius Smart Meter monitors the grid parameters on the public grid and passes grid this information to the inverter. After a defined measuring period, the restored public grid is deemed to be stable.
The rest of the home network is not supplied with power in this case. The following points regarding cabling must be considered: 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-cur- rent circuit breaker of the emergency power circuits.
Fronius Symo Hybrid because this emergency power network has a fre- quency of 53 Hz. Transition from The public grid is monitored by the inverter's internal grid and system protection unit feeding energy and by the Fronius Smart Meter connected to it.
