6.2.5.8.1 Island Protection
The active anti-islanding protection of the inverters is achieved by shifting the
frequency of the inverter away from nominal conditions in the absence of a
reference frequency (frequency shift). It is enabled by default.
6.2.5.8.2 Volt-var Response Mode
The QU Curve is enabled by default. The volt-var response mode changes the
reactive power absorbed or supplied by the inverter in response to the
voltage at its grid-interactive port. The diagram and table below are the
response mode required for the volt–var response according to the standard
of AS/NZS 4777.2:2020.
