As far as I know, there are pre-build nut-2.2.0 packages available for
Debian.

So are unclean shutdowns. If you can't lower the load on your UPS (which
seems to be the root cause of your problems), it might be better than a
corrupt filesystem. Choose your poison.

If this is right after your system restarted, the UPS probably didn't
shutdown because of a low battery. Or the charge indicator should be
really way off the actual charge level. I'm not familiar with the Pulsar
Evolution UPS range, but on my Evolution 650 it gives a decent indication
of the charge remaining.

> battery.charge.low: 30

See here? The UPS won't signal a low battery until it reaches 30%
remaining capacity. If it nevertheless shutsdown automatically, this is
probably due to an overload or -temperature situation, or a crappy battery
or battery connection.

You have nothing connected to it? Or is it just reporting erronous values?

As I already expected, this is probably only a subset of what your UPS
supports. You really should upgrade to a more recent NUT version and the
'newmge-shut' driver (or 'usbhid-ups' if you have USB available).
