The combination of Victron products with the BMZ ESS 7.0 battery has been tested and certified by the R&D departments. The combination is actively supported by both companies.
All 48V Multis and Quattros. And always a Venus 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. The Venus device takes care of sending the necessary canbus keep-a-live message to the ESS battery. Without it, the battery will open its internal emergency relay after 10 minutes.
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 Venus-device.
Then, plug a VE.Can terminator in the other VE.Can socket on the Venus device. Two VE.Can terminators are included with the package of the CCGX 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 Venus device.
