HPE R/T3000 G5 UPS Keeps flicking from utility to battery randomly for short periods

We have updated one Server with ne newest SPP package from HP (2024.04) and we can confirm that this fixed the problem.

We now have Power Management Controller Firmware Version 1.1.4

The other server on whom the problem still exists is on version 1.0.4

(iLO Power & Thermal -> Power)

We measured 70 Volts at the protective conductor while the problem occurs and 260 volts on the input.

I think HP needs to dig into this because this can be very dangerous for the hardware and people if a rack is not correctly grounded.

Our electricians were also very confused because they never saw such a problem caused by a power supply firmware.
