... and back feed into the grid with electricians working on it during a power cut ...

always wondered how 'solar to grid' units stop feeding the grid when the grid goes down?

It is 100% false. It is not possible for your improperly connected backfeeding generator to injure or kill a lineman, it can only provide an opportunity for them toiinjure of kill themselves by not following their mandatory safety procedures.

I have actually done something similar to that plug to connect my generator to the house service panel in an emergency. In order to be sure that I didn't feed the grid I switched off the main breaker in the service panel.

Since then I have hardwired a receptacle for the generator that goes through a dedicated circuit breaker along with a mechanical interlock that prevents that circuit breaker from switching on unless the main is switched off.

I wold think either a transfer switch auto or manual or a big ass diode

All units feeding into the grid take the grid as a load and use the frequency for synchronisation. When the voltage is missing they stop. I do not know details, but in case of a power cut the voltage would drop, even with a certain current being fed into the grid.

I am just working on going off grid, too many power cuts, too expensive and I do not believe that the grids will stay stable in the future, see what happened in Spain recently.

I have a younger step brother that pulled that crap. Face resembles the little trouble maker in the photo

Reverse power relaying does the trick. Trips the circuit breakers on the load side of the inverter, which then disables the inverter output. Not much difference from a conventional turbine generator. Was in the biz for nearly 40 years and wrote software for auto-synchronizing big generators to the grid with PLCs. Fun jobs those.

OK, HOW does it sense that the 'line' is 'dead' as the solar array is supplying power to the 'grid' or 'line'. To me it's a chicken and egg problem. I tried asking 'solar sellers' got nowhere of course.

It very much is a chicken/egg situation. If you want to take this private and let the jokes resume (before we become the butt of the jokes while we’re nerding out), pm me and I’ll be happy to explain in detail. I’m old and retired with lots to say and the time to say it.

Maybe closed captions don't always represent the spoken word. I believe she said "chaotic, erratic policies":

Why not start a separate OT thread so other who may be interested can follow...
