I propose to ignore these values for the 'Pulsar Evolution'.
Other (non-MGE) HID drivers regard these HID paths as indications for
'battery.voltage(.nominal)' and even some MGE devices do. Yesterday I
found that the MGE Galaxy UPS reports the battery voltage in
"UPS.PowerSummary.Voltage" in its XML report (and
Therefor, it is probably a bug in the UPS firmware that we should deal
with on a model specific basis. Since your UPS already reports the correct
'output.voltage(.nominal)' values, I think there is no point to add these
HID paths as fallback for these NUT variables.
