Here's one, the battery is topped up off-peak, then when a rolling blackout inevitably comes along, bingo, you can still fire up your gas central heating boiler and run the circulating pump using the battery juice. Kind of handy in January in North Scotland.
The problem is that if the power goes off, the battery power has to be kept totally isolated from the incoming supply, which is apparently not a simple matter.
If its not, there is a risk of electrocution to anyone working on the supply as it can be live from the consumer's battery setup. As I understand it, the standard arrangement at the moment is that if the supply fails, the backup must switch off too.
Perhaps I've slightly misunderstood, hopefully someone with better knowledge will be able to explain it in more detail.
