Yeah, non-USA for this atm, as much fun as it would be to plug such a system into an apartment.
I believe that the US requires that a direct-feed system has to plug into a physical kill switch setup to prevent back-feed of power during an outage.
Still pretty neat, though!
These systems automatically turn themselves off during an outage.
That's great, but it doesn't matter unless it has the physical cutoff that's required to bring that kind of system up to the current electrical code for such a system.
Physical shutoff via relays is required by the standard. We've just been through a scandal where a manufacturer skimped out on putting them in and had to recall the devices.
