MPPT 450/100 display as "NOT CONNECTED"

Hi everyone. New Victron user here :)

I have :

  • an MPPT 450/100 connected using VE.Can to a Cerbo GX (terminator connector used on each one)
  • a Multiplus-II 48/8000/110-100 connected using VE.Bus to the Cerbo GX
  • Pylontech batteries connected to Cerbo-GX using the good Victron cable to the Cerbo-GX
  • DVCC is on ( charge informations are provided by the Pylontech BMS)

I have a strange behavior with the MPPT not showing as PV Charger on the VRM online and marked as "NOT CONNECTED" on Device List.

More strange, when I connect to the MPPT solar, or when I reboot it, it appears in both device list and VRM, but only for approximatively 30 seconds and then it desappers again.

I monitored the device list and sometimes, the MPPT is showing up by his own, but only for a few seconds.

Note that the device itself is working well.

I have tried using another cable, but the behavior's still the same.

Has someone experienced the same problem ?

Maybe it is "off" at night with no PV production ?

Thanks for your help or advice :)
