12.9 Behavior in the Event of a Failure in a Three-Phase System
You can influence how the Sunny Island reacts to failures occurring in a three-phase system using the
parameter "250.30 RnMod". The parameter is set to "RunAlways" at the factory. This means that the
master ignores all errors at the slave devices.
If you set the parameter to "StopAlways", the system will be put in standby mode upon detection of a
fault at the slave devices. Faults which can be removed via an autostart are not included.
