I think I read the error occurs if there is >5v difference between
neutral and ground. The Strange thing is that it's happening at the
same time every day.

good luck. APC has a little guide for troubleshooting them, but never
much detail. we have a couple sites that always have it, never had any
impact. I suspect its overloaded ground. Maybe the smart meter shunts
voltage to ground for some safety verification or something like that,
or more likely to identify utility theft since all those smart meters
are about is profit

I have a UPS that I recently installed pulling a 'Site Wiring
Fault' for 20 seconds a few times a day, at the exact same time
daily. There are no other local electrical device at the location
that I can find turning on or off at the same time, or that would
have this kind of regularity.
There is a smart meter at the location, could the smart meter be
doing some polling that would cause this? I have another
Identical UPS off the same utility HV line, but different
transformer and meter, and it does not have any errors.
Has anyone seen these before and been able to track down a cause?
On the APC forums, one reply was to simply disable the alert,
saying otherwise you'll descend down a never ending rabbit hole of
diagnosing and tweaking your electrical plant.
