Hi @BlueLghtning , welcome to the Community!
The first thought that comes to mind is that you may have the VE.Bus Smart Dongle's power supply wires connected to the DC I/O connection bolts of the MultiPlus and/or have the Dongle itself placed in or on the MultiPlus - is this the case? If so, please remove them and connect the VE.Bus Smart Dongle to the battery terminals and mount the Dongle to the batteries as specified in the user manual.
If the Smart Dongle is installed correctly, however, and the issue persists, please post additional details including photos of the installation if possible, as well as the FW version of both the Dongle and the MultiPlus, and we'll see if there's any additional troubleshooting that we can offer!
Hi, did you ever find the solution to this?
I have the same issue, I have wired up a VE.BUS BT Dongle to my Multiplus 12v 3K. The dongle is wired up to the main bus bar, not in the inverter, I have updated the software on both to the latest using the VE.BUS to USB dongle and I have even bought a Victron RJ45 cable and still have the exact same issue.
It will all boot up and work but will cut out about every 30 seconds and reboot. You can see in the app through the dongle that it is as soon as it has got all the information (going from unknown to then give the inverting/battery details) as soon as it is showing the details it cuts out about 3 seconds later and goes through the same process again.
Don't know what else to try, might it be a faulty dongle as the Multiplus works fine without it?
