An inverter DC imbalance exists SMART_UPS 3000 RM rack

Anonymous user · ‎2021-06-29

after a power cut

power went back and one of my two ups(SMART_UPS 3000 RM) I get a loop with this message

An inverter DC imbalance exists

followed by

The output power is turned off

Please help I have no physical access for the moment

What can I do to make it transmit power to my servers connected to this ups, I do not have other plugs to connect them.Any possibility to make it by pass?

Any ideas welcome, I will have onsite access within 24 hours but I would like to know what to check/test.Is it the ups that's faulty or the coming power from the building?

Thanks in advance

Do you know the exact model of the UPS? If it does not have it's own automatic or manual bypass (which only select 3000VA models provide) then you may need to move it to a different power source. For the future, a wrap around bypass panel (also called a service bypass panel) can provide power output if the UPS is not functioning properly.

Besides physically resetting the UPS, I can't think of anything remotely that could fix this because the inverter converts DC to AC and is a critical component of the UPS. Via the management card you could try controlling the output to turn it off/on but it sounds doubtful that it will change anything.
