A bit of a hijack but..

You can't - at least the ones I know of will turn off for safety once the grid is lost.
Imagine if Mr ElectricMan turns off the power to your street and works on the cables, your grid-tie inverter is still holding the cables live and would give him a rude wakeup call.

edit - how rude Omarhosny, a double post.
