My Chinese built inverter functions just fine without Internet, but I'd have to take over doing what Amber Energy are doing if I lost access to the cloud.

But that's residential scale: at grid scale these things wouldn't be online in the same way anyway.

and what if they can use your inverter to destabilize not only your netwrok, but the local grit as well? and how far it can go if sychrnoized with malicious intend?
