Yes I forgot the h.
Islanding is automatic with Tesla.
After the fires and blackouts down here lots of people bought gensets thinking they could just plug them in and go for it.
That came to a screaming halt.
Same thing has to have an islanding system to be legal.
What do you mean by islanding system for gensets? I have a caravan style inlet plug on my home that I connect to my genset and an isolation switch which isolates my home switchboard from the mains system and is then powered by my genie.
I had a warning buzzer fitted to the mains supply so that it will alarm when the power goes back on and then switch back to mains supply
Haven’t got to try it out yet
