With the advent of PV feed in, how do DNO guys safely isolate?

Did they ever?

Have they always worked live or do they now have to work under the assumption that everything is live?
 
All grid tied generation equipment should have “island protection” this means if it can’t detect a mains frequency it will not try to feed into it.
 
The P.V inverter is powered from the DNO mains.
No mains, no power from the panels will get onto the DNO network
They don't need to isolate each P.V, but they always work safe.
That makes sense, I'll sleep soundly tonight.
