In Australia, the inverters are supposed to cut out with a voltage over 254V.

Australia used to have a nominal voltage of 240V but was reduced to 230V some time ago. I don't think the supply companies have bothered to change the taps on too many transformers so we run close to the maximum at times.

I am glad I am no longer responsible for any of that.

A few years ago I built a disturbance recorder based on a MX170 to record the AC waveform for a number of cycles before and after a sudden change in voltage.
I must get back to it. Another half done project to finish.
