Unfortunately, I have no knobs left to turn in the powerpanel software.
I've varied every parameter and checkbox feature available in the data
I've already provided.

I can try to force the UPS into a few different situations prior to
starting up the software and we can see if those values change during
the initial sequence.

1) I will cut the power to the UPS and have it running on battery before
starting the powerpanel software.

2) I will disconnect the batteries in the UPS and see if that changes

Can you think of any other scenario that you might like me to try?
