The combination of Victron products with the BMZ ESS battery has been tested and certified by the R&D departments. The combination is actively supported by both companies.
Compatible BMZ models:
All 48V Multis and Quattros. And always a GX device is necessary in the system, since that has the canbus port which is used for the (required!) communication between the ESS battery and the Victron system.
To use the BMZ ESS in Victron system, it is necessary to use a Color Control GX or Venus GX. On first commissioning an external power supply (Not the 48V from the BMZ-Battery) is needed. The GX device sends a keep alive signal to the BMZ ESS via canbus. This will only be send once the canbus baud rate is changed (see 5. GX device Configuration). Without it, the battery will have a communication fault and shut down after 10sec.
Use the VE.Can to CAN-bus BMS type B Cable, part number ASS030720018. Plug the side which is labeled Battery BMS into the BMZ BMS. Plug the side labeled Victron VE.Can into the GX device.
Then, plug a VE.Can terminator in the other VE.Can socket on the GX device. Two VE.Can terminators are included with the package of the GX device as an accessory, only one is used. Keep the other one as a spare.
More information about the cable can be found in its manual.
Without properly connecting this cable, the battery will stop charging/discharging after several minutes. Also, the battery will not show up on the display of the GX device.

Enabling DVCC changes a GX device from a passive monitor into an active controller. The available features and effects of enabling DVCC depend on the type of battery used. The effect also depends on the installed Victron components and their configuration.
