duction
UCs or utility companies can prescribe feed-in limits for an inverter (e.g., max. 70% of the
kWp or max. 5 kW).
Dynamic power reduction takes into account self-consumption in the household before the
power of an inverter is reduced:
- An individual limit can be set.
- A counter for determining self-consumption per S0 can be connected directly to the
inverter (Fronius Galvo and Fronius Symo only).
- A Fronius Smart Meter can be connected to Fronius Datamanager 2.0 at the D-/D+
connections for Modbus data.
Power limit
Option to define the maximum output power of the photovoltaic system.
(1) No limit
The photovoltaic system converts all available PV energy and feeds it into the grid.
(2) Dynamic power reduction limit for the entire system
The entire photovoltaic system is limited to a fixed power limit.
(3) Field for entering the total DC system power in Wp
This value is used as a control reference and also in case of errors (e.g., counter
failure).
(4) Field for entering the max. power in W or %
If no counter has been selected in the "Counter" menu item:
Max. power generated for the entire system
If Fronius Smart Meter or S0 inverter has been selected in "Counter" menu item:
Max. energy fed into the grid
