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!
I'm guessing the commenter above is in the EU and operating at 50Hz normally, so running at 60Hz wouldn't be a great idea. A backup battery and such operate in the same way when islanding.
Yep. And in my case, the backup battery is connected to another DC input on the inverter and the inverter pretty much manages everything. As I understand the documentation, there is no other way to use solar AND a battery at the same time as a power source for islanding. Switching over manually with a short disruption in-between is always possible of course, as is charging an AC coupled battery from an islanding solar inverter.

IIRC some inverters are able to sync up with alternative power sources, but the documentation is extremely limited and seems to be reserved mostly for large-scale systems. I know my Solaredge system has slowly been implementing using both at the same time, but the documentation is pretty unclear as to how this works. I know at the very least it'll allow you to use a 2-wire start to kick a standalone generator on when the batteries are low, but don't know much else about how it's currently set up
