We are currently working on integrating 20x Meritsun 48V 200Ah (48/200) batteries in parallel with a Victron Cerbo GX, but we are facing challenges with communication and data retrieval.
Key Questions & Issues:
- Communication Protocol:
- Should the connection be made via VE.Can or BMS.Can?
- The available Meritsun documentation Meritsun to Victron does not clearly specify which protocol is best when integrating with Victron systems.
- Data Retrieval Issues:
- Despite following the manufacturer’s guide, we are unable to retrieve any meaningful battery information.
- The battery bank is connected, but no data is being displayed on Cerbo GX or VRM.
- Are there any specific VictronConnect or VRM settings that need to be configured for this setup?
- Termination & Proper Wiring for 20 Batteries in Parallel:
-
How should the CAN communication be wired when using 20 batteries in parallel?
-
Do we need termination resistors, and if so, where should they be placed?
-
Is there a recommended wiring diagram for this type of setup?
-
Battery Model: 20x Meritsun 48V 200Ah (48/200), connected in parallel
We would really appreciate any insights, experiences, or recommendations from the community to get this setup running correctly.
