I'm graphing my UPS in and output voltages and they haven't changed
much. Max/Average/Min has been 254/249/247 volts with a steady decline
since September, the minimum being now.

If its power related, its more likely to be spikes rather than just it
being over 240V.

Nighttime electricity is noisier.
