I think plugin batteries are coming too. Right now (well 27th August) you can plug your inverter into a battery but you can't connect the battery to a ring main you have to connect devices directly to it. That is under assessment though so there's a good chance they could copy the way Germany does it, just like they're doing with the panels.
