Setting: Manual
All parameters can be configured independently.
Setting: Predefined zero current
Dynamic grid support active on account of immunity to interference and
zero current feed-in. During a voltage incident, the current in the in-
verter is reduced to zero.
All parameters are pre-configured, only the activation threshold for zero
current has to be configured.
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 of active current with dynamic reactive current. The in-
verter feeds in as much active power as available. If, as a result of this,
the maximum continuous current is not achieved, the inverter supplies
additional reactive current according to the formulae (2) and (4) up to
the limit of continuous current.
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.

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.
Amplification factor for the negative sequence used in the calculation of
the reactive current using formulae (2) and (4). Can be configured inde-
pendently for drops and spikes.
