FYI - Just confirmed with the installer that...
although not designed as a feature or advertised in any way there will be a mains "disconnect" inside of the Service Gateway device. The Service Gateway is basically the brains of the whole system and decides when to discharge/charge batteries, use solar, or use grid. Because there needs to be a mains breaker here "I can simulate a grid outage."
If we've sized this thing correctly... I will be able to go 100% solar + battery manually. Say, for instance, when I'm listening to Pink Floyd.
If I leave the breaker alone then the gateway decides automagically when to do the switching based on conditions.
