I think I get that, thanks. So an Island grid is less stable and could cause itself damage if two microinverters say are trying to sync up to each other vs a beefy, stable main grid?
So how does a backup battery system work when islanded? Typically also at 52Hz?
Or can it go into a 60Hz beefy mode?
It would be nice to get all the little island solar inverters working when the grid goes down!
