Priority – Reactive cur-
rent limitation | Active
current priority
Priority: Reactive current priority
Dynamic grid support active on account of immunity to interference and
fast feeding of residual current. The inverter feeds additional reactive
current according to the formulae (2) and (4).
Priority: Effective current priority
Dynamic grid support active on account of immunity to interference and
fast feeding with active current priority. The inverter feeds in as much
active power as available. If, as a result of this, the maximum continuous
current is not achieved, the device supplies additional reactive current
according to the formulae (2) and (4) up to the limit of continuous cur-
rent.

If one or more phase/phase or phase/neutral conductor voltages move
above the configured threshold, the inverter changes to zero current
mode. The total current is regulated to virtually zero.
Reference voltage
80 – 110 [% Unom] /
100 [% Unom] /
0.1 [Unom]
Nominal value of the phase/neutral conductor voltage used as a refer-
ence voltage for formula (1) and (3). Adjustable in the range from level 1
undervoltage protection to level 1 overvoltage protection.

pendently for drops and spikes.

Dead band
2 – 120 [% Uref] /

Dynamic grid support through fast feeding of residual current activated
in the case of voltage events with a voltage change greater than the
dead band.

Standard
: The reactive current according to the formulae (2) and (4) is
fed as
additional
reactive current. The means that sum of the pre-fault
and additional reactive current is fed in.
Only dynamic:
The reactive current according to the formulae (2) and
(4) is fed in as absolute reactive current. This means that regardless of
the reactive current before the voltage event, only the reactive current
is fed in according to the formulae (2) and (4) is fed in during the voltage
event.
