    1000 W In this case, the inverter would need to reduce the PV power to 0 W, as the output power of the Fronius Symo Hybrid 3.0-S is max. 3,000 W and the device is already fully utilised through the discharging.

    Settings – System overview System overview PV generator If there is no solar module connected to the Fronius hybrid inverter, the PV power option must be deactivated. The connected PV power must be entered in the field underneath. Battery If a battery is connected to the Fronius hybrid inverter, it must be activated here.
  • Page 110 If the function is activated, the inverter remains permanently connected to the grid so that energy can be drawn from other producers at any time. Once the meter is connected, its position must be configured in the Fronius Datamanager. Several Fronius Smart Meters can be installed in the system. A different address needs to be set for each Smart Meter.

  • Page 111: Settings - Meter

    A primary meter and several optional secondary meters can be selected. The primary meter needs to be configured first before a secondary meter can be selected. Fronius Smart If the Fronius Smart Meter is selected as the meter, the meter position needs to be con- Meter figured in the "Settings" field.

    With the Fronius Symo Hybrid, any PV power that is not allowed to be fed into the grid is used to charge the battery instead so that it does not go to waste. Dynamic power reduc- tion is only activated if the battery is full or cannot be charged for some other reason.
