General System Interfacing
Victron Energy Troubleshooting
- MultiPlus-II installation shuts down with 'High DC Ripple' errors during Redflow battery state transitions
- The BMS "Discharge-Disabled SoC Threshold" parameter - Discharge control after batteries are fully discharged
- Victron system will not charge ZCell batteries
- Handling devices with high surge or startup current draw on off-grid sites
- MultiPlus-II unit stops with 'Error 11' after the AC grid is connected
- CANBus interface between BMS and CCGX is not working
BMS
- Using the BMS Digital I/O engine to send signals to external systems
- Providing dry-contact relay status signals using a MODBUS-TCP relay module
- Interfacing to the Redflow BMS using MODBUS-RTU (RS485)
- Querying the Redflow BMS using MODBUS-TCP or JSON
- Cabling considerations when connecting more than 12 batteries to a single BMS
- Using SPS mode exclusively (no RUN mode batteries on the system)
Victron Energy Interfacing
- Stable Victron site operation for on-grid/off-grid hybrid sites with AC solar and Redflow batteries
- Creating MODBUS-TCP Digital I/O Endpoints for Victron GX devices
- Off-Grid Deployment Guide for Redflow and Victron based systems
- Additional DC Capacitors required for MultiPlus-II product series when used with Redflow ZBM2/ZCell batteries
- Configure BMS to update system SoC to a CCGX using MODBUS-TCP (superseded)
- Recommended initial commissioning sequence for large systems (multiple Victron Energy inverter/chargers per phase)
