I am getting this "#1 device switched off" problem and cannot find the reason for it.
Here is what Victron documentation is saying.
VE.Bus Error Codes Error 1 - Device is switched off because one of the other phases in the system has switched off One of the phases in a multi-phase system has failed. Commonly because of a Low battery, Overload or High temperature alarm. When this happens, the other phases will show VE.Bus Error Code 1. Trouble shooting: Look for the failing phase, which will be the phase that is not showing VE.Bus Error Code 1. And check the LEDs on that phase to find out what the reason was for the shut down. Diagnosing on VRM First make sure that Automatic alarm monitoring is enabled; that is necessary to create the Overload and Temperature errors in the log. You will see Overload and Temperature alarms occurring at the same time as VE.Bus Error 1. Note for split- and three-phase systems: VRM, nor the GX device, will indicate on which phase the overload or the temperature alarm occurred. To find out on which unit the error occurs, go to system after it has switched off. And look on the LEDs. The unit with the overload or temperature alarm, will have the corresponding alarm LED lit continuously. The other units will indicate a VE.Bus error, indicating that they miss one unit. Recovery: auto-restart once the error is gone.
In my case there is no overload, temperature or low battery.
System simply drops the output power and auto-restarts after less than a minute.
Grid Input voltage is ok as per VRM. My Grafana also is not showing grid problems.
I have no way to see which phase is causing it because problem is gone before I can get to do system and see the LEDs, especially when it happens in the middle of the night and I have to look for the flashlight. :(
It is 3 phase system with 2 MP-II 48/3000 parallel per phase.
Any ideas where and how to look for the culprit?
