The topic of this thread is solar+battery+grid, I’m not so certain we destroyed the thread although we are getting deep into it.
As for antiislanding failing. I don’t see how that’s possible. Antiislanding means that the inverter cannot operate if grid power isn’t present. Grid tie inverters get their power to turn on from the grid, they can’t even be on without grid power being present.
I agree zero export isn’t needed for saving excess power into batteries. But it is also not just for people that don’t get paid to export. They might want to choose to not export due to not getting paid enough to export or not getting enough credit etc. Or in my case-area would have to spend a small fortune to have solar if they did export. Some people don’t have the money or know how or want to install an offgrid setup that is large enough to cover all of their homes usage. Yes they should still get the permits etc but sometimes like in my area they cost a lot. Imo my system is very safe and my system does not send anymore power back into the grid (when loads shutoff) than some motors sometimes do for a couple seconds.
Daromer your initial comment was that if the OP didn’t want to sell to the grid then they should have an offgrid system, which is generally the right way to think. I was mentioning grid tie with batteries or hybrid and zero export (legally done or not) so the option was there, that they don’t have to have a much more expensive offgrid setup that covers all of their loads-surges. Grid tied mode with or without Zero export is another way to implement solar+battery+grid. And if there’s no other option due to the extreme hoops-cost in some people’s areas they could choose to use grid tie or hybrid inverters with zero export. Although it might not be done legally, the electric company most likely would never know about it or care if you were not sending power past your meter. And as I explained above it can still be done safely
