Repetitive Easy Solar Overload alarm while no load

Hi, my EasySolar keeps giving overload errors, then shuts itself down and starts up again.
VE.Bus System - EasySolar [276] Overload L1: Alarm

EasySolar v566, Cerbo GX v3.73,
LifePO4 200 Ah battery.
I do not have any problems on the DC side. Charging also works fine via solar and Orion.

I have tried everything I could find on the community site:

  • Switched off all AC circuit breakers, input and output.

  • Completely disconnected all DC power for 15 minutes.

  • Replaced even the main fuse

  • Checked all cables

  • Set the system to charging only mode

Nothing worked.
Any ideas?

Is the battery idling when this happens? Sometimes with small draws they change bahaviour to prevent the parasite draws and are actually diconnecting which the inverter will notice.

The overload alarms happen in this state as well?

Does the overload alarm appear when it is left like this as well? Or were you just doing this to clear the alarm?
Overloads can also happen from wiring shorts.

Yes, in both states, charge only and with all AC breakers off I get the overload alarm. Also after switching it off and on in this states it keeps appearing.
