Dynamic power
reduction by
means of invert-
er
Energy companies or grid operators may impose feed-in limits on an inverter. Dy-
namic power reduction takes account of self-consumption by the household be-
fore the power of an inverter is reduced:
A counter for determining self-consumption of the S0 can be connected directly
to the inverter – see chapter Explanation of the multifunction current interface
on page 22
A feed-in limit can be set in the Basic menu under Signal input – S0 meter – see
chapter Menu items in the Basic menu on page 96.
Setting options for S0 meter:
-
Grid feed-in limit
Field for entering the maximum grid feed-in power in W. If this value is ex-
ceeded, the inverter regulates down to the set value within the time required
by national standards and regulations.
-
Pulses per kWh
Field for entering the pulses per kWh of the S0 meter.
Zero feed-in is possible with this configuration.
When using the S0 meter and power reduction by means of an inverter, the S0
meter must be installed in the consumption branch.
S0 meter in the consumption branch
If dynamic power reduction is subsequently configured using the Fronius
Datamanager 2.0 (Inverter user interface - UC Editor menu - Dynamic power re-
duction), dynamic power reduction must be deactivated using the inverter (In-
verter display - Basic menu - Signal input - S0 meter).
