When a grid tied system loses the grid it shuts down to protect the inverter and not back feed the grid. If there was a battery bank in between the panels and inverter and the inverter had an automatic transfer switching system it would keep power on until the batteries were drained. A larger group of panels would lengthen the battery time.
Its not a legality issue, its a financial one.

I misunderstood the first part. My apologies.
If I have a off the grid house with solar panels, I get power from the panels do I not? Assuming yes, why can that not be done on the grid and just have a switch, like they do for a house that has a generator, which cuts off power from the grid?
