The Sunny Island also has an integrated anti-islanding feature which prevents islanding on the utility
grid. If this process is triggered, the system also completely changes to stand-alone mode without
interruption.
The Sunny Island can be integrated into different system constellations. The following graphics show
the devices of a Sunny Island system and the different wiring options (single-phase / single-phase
parallel, split-phase, double-split-phase and three-phase).
