While fundamentally working, I'm having a few issues with the driver...
The default voltage quads (for every model) are way off... Showing
~95v when it should be ~117V. I've changed the 4th/final coefficient
to +5.0, but haven't tested extensively (with fluctuating voltages).
The input/output voltage appears to be swapped _most of the time_.
When doing a battery test, or when unplugged, the input stays steady,
and the _output_ voltage reports a drop to ~15V. OTOH, when the UPS
is shutdown, the ordering appears correct, as the input stays steady,
and the output shows ~5V.
For the above, the Powercom upsmon software appears to special-case
those ~5/15V results, and on the next update, report it as 0V. I have
no idea how to even special-case the screwy input/output-swapping
behavior...
