Multiplus 2 GX Communication problem

Hi

I have several installations in which i used a Victron Multiplus 2 GX and I had some problems in most of these installations, i think the problems that I am facing are related to the communication with the built in GX device.

These are some of the problems that I faced:

1- The screen turned off in 2 installations,

2- The Connection with the GX device embedded in the inverter is not good, no data is transferred to the VRM, noting that all the connection cables are new, it works only after rebooting the remote console, but after some time, the problem returns,

3- The icon of the PV solar charger disappeared and then appeared after rebooting the remote console, but after a few minutes it disappeared, the system saw that there was no PV so the batteries were discharging, Also noting that the connection cables (VE direct in our case) between the chargers and the inverter are new as well,

4- The GX reboots randomly, and in the VRM the inverter appears OFF, the client thought that there was no electricity in the house while is was ON.

Hoping to get some help regarding this topic

Thanking you

Hi, I am experiencing the same problem at one of my clients with a three-phase 5kva GX installation. The no data alarm will trigger and then after a hard system reboot it will keep for about 2 to 3 hours and and it will fail to communicate again. It has a wifi as a main connection and LAN connection as backup, which are both functional. How do I proceed to get the GX units for the 3 X 5 kVA inverters replaced?


Thank you
