The Last Power Event is "AC utility power too high, use battery power at date+time".

I'm no expert, but 1,824,680 over voltage events in the last 24 weeks seems a tad excessive.

73,630 in the last week - 303,620 in the last 4 weeks, 931,319 in the last 12 weeks.

Seems to be a consistent issue.

What remedial action should I be taking? If any.

Is (for example) the voltage coming out of your wall sockets 240v but the UPS is configured to expect 220v? If so, a UPS can 'buck' (reduce) the output voltage. Can you change the UPS settings to tell it that 240v is your normal voltage so it doesn't need to freak out? :)

I can see where it tells me the current voltage is 236V, though it did say 239V a few minutes ago.

Looking to see if I can find a setting I can change from 220 to 240.

UPDATE:

My UPS (CyberPower BR1200ELCD) does not support setting voltage thresholds.

But the specs say it supports 230V +/- 10%.

While sticky-beaking through PowerPanel I found it wanted a software update, which I have applied.

It seems for now that those particular warnings have stopped.
