How to tell why system is dropping grid

The last couple of days my 3 phase multiplus II 5kva system has been deciding around 11am to disconnect from the grid and run off of battery/solar until around 4pm.


I presume the system is upset about grid voltage or something, but I can't actually spot any place inside the Cerbo GX that may indicate what it considers to be the problem.

As far as I can tell, the grid voltage on all phases is less than the overvoltage 10 minute average value configured in ve.config for each multiplus.

Is the system connected to the internet?
If yes you could use the VRM portal to take a look at some diagrams maybe you can see there a voltage drop or something like that.
