We have regulations here in Germany (EU wide even if I am not mistaken). The solar inverters used are required to shut off within I think 200ms of the 50hz grid power going down. The inverters sold here can’t output anything without grid power being detected on the AC output.
Why is everyone in this thread making assumptions and spreading fear instead of actually looking up how it works?
Does it come with a battery that’s not rechargeable and only lasts for exactly one playthrough of the game after which you throw the whole thing in the trash?
