My system, from time to time, is switching to inverter mode for couple seconds at a time.
I do not see the obvious reason why it does that.
Is there a log of the events with the record of the reason for this switching?

System monitoring and event log
What is your configuration?
Do you have a GX device?
Is there an internet connection available?
Anyone willing to help?
Again I had my system go to inverter mode without apparent reason.
I can understand it happening when grid voltage drops below limit and it occurs between testing points on the VRM graph, but events are supposed to be reported regardless of the log interval set in remote control.
The resolution of VRM may not include your (short) problems. Even in the detailed view it may not show. I assume you already tried setting the log interval to 1 min.

Or maybe the XLS download from VRM does include something which does not show in the graphs?

Thank you for the link. I will play with it. Fact that you can get samples every 2 seconds is interesting.
Today I noticed an interesting situation.
System reports a grid failure and power assist!
Why would there be power assist in the system that is not connected to any load other that the multis themselves?
My system is not connected to the house circuits jet. It is just running itself and reacts to the grid.
From time to time grid voltage goes out of the limits set for it, and system goes into inverter mode. That is recorded by VRM in the alarms section as a grid failure.
Problem is that not every event, of switching to inverter mode, is recorded by VRM in the alarms log.
I can see them in VE,Bus,State graph but not in the Alarm log.
You are correct, I have now set the log interval to 1 minute, but the events are suppose to be recorded regardless of the log interval., and it is not so. Things happen but are not recorded in the log.
You can see it better when I zoom in:
The event on 13:30
The event on 17:00
You can see, that only events that happened at around 13:30 were recorded (not all BTW).
What happened in the other two instances?
Is there a lower time limit for the duration of the event to be notices and incuded into the Alarm log?
Also this power assist puzzles me.
