Can’t upgrade VE.BUS firmware with BMS connected

I have a Multi 5000/48 with SmartLithium batteries connected with the Victron VE.BUS BMS. AFAIK there’s no information regarding BMS in the VE.BUS FW Upgrade documentation. VictronConnect says I can’t upgrade the FW when there’s a BMS connected, so I wonder what’s the recommended procedure in order to install the FW upgrade?


The reason for the upgrade is that I get “VE.BUS Error 11 reporting requiring minimum VE.BUS firmware version 454.”. I’m running v430.

Hi @RallyHagge


What exactly is the problem? you disconnect BMS as instructed, does something go wrong?
