SMA Sunny Island SI6048 W331 Grid/generator disconnected
For Sunny Island to say "anti islanding" it has to think it is on grid. Maybe a different quick-start configuration would fix that. But without it ever see power on its AC input it shouldn''t ever close those relays. You don''t have AC1 and AC2 connected together, do you? (people have done that.) What is supposed to keep the battery charged?

5 FAQs about [Norfolk Island islanding in smart grid]
Should micro-grids be alerted about unintended Islands?
Micro-grids (MGs) have proven to be a viable alternative in such circumstances. However, these occurrences are highly unpredictable, resulting in unintended islands of MGs with negative consequences. As a response, alerting its distributed generations about unintended island is indeed a crucial issue for enhancing grid resilience with MG.
Why do we need a proper islanding plan?
A proper islanding plan may make the occurrences less severe, allowing for a more rapid and effective reaction. A system that is not connected to the main power grid but energized by distributed generators (DGs) is referred as an island system (Dutta et al. 2022 ).
