4. Configure CAN-bus Speed: BlueNova batteries typically use a CAN-bus speed of 500kbps, which is the default for new batteries. Newer batteries may allow selectable speeds of 250kbps or 500kbps, sometimes requiring a firmware update for older models. If a setting change is needed, use the GX device menu path //Settings -> Services -> CAN-profile//.
5. Understand DVCC (Distributed Voltage and Current Control): DVCC is automatically activated when a BlueNova battery is connected via CAN-bus to a GX device with the latest firmware. This feature can be enabled or disabled in the Settings → System Setup menu.
6. Shared Voltage Sense (SVS): SVS is enabled by default when DVCC is active. It can be disabled in the Settings → System Setup menu if necessary.
7. Limit Charge Current: The user-configurable maximum charge current setting can generally be disabled for BlueNova Energy batteries.
8. RacPower Specifics:

• • RacPower (BP & DU) range BlueNova Energy batteries require CAN-bus terminations, which are supplied with each RacPower unit.
  • For RacPower batteries (latest "DU" and "BP" models) with CAN-bus and RS485, contact BlueNova Energy Technical Support for correct interlink comms cable configurations, especially if a BlueNova Energy BMAC Online unit is present.

9. CCGX Limitations: Note that it is not possible to connect both VE.Can products (such as VE.Can MPPTs) and a BlueNova Energy battery to a CCGX simultaneously. For such setups, a Cerbo GX, which features two separate sets of ports, is required.
10. Monitoring Multiple Batteries: To monitor individual paralleled BlueNova Energy batteries, a BlueNova Energy BMAC Online unit can be installed between the batteries and the Victron Energy GX device.

Common Compatibility Issues and Solutions

Victron System Configuration for BlueNova Batteries

Integrating BlueNova Energy LiFePo4 batteries into a Victron Energy system relies heavily on proper communication protocols and firmware synchronization. The Victron GX device acts as the central hub for this communication.

Firmware Requirements

Maintaining up-to-date firmware across your Victron system components is crucial for optimal compatibility and performance with BlueNova Energy batteries. The following minimum versions are specified:

• GX device firmware: Minimum v2.02 (recommended latest).
• ESS Assistant version: 164 or later (released in November 2017).
• BlueNova Energy 123SmartBMS firmware: v5.13.
• BlueNova Energy BMMC firmware: V3.5 +.
• Multi/Quattro firmware: 422.
• MultiGrid firmware: 424.
• GX device firmware (for DVCC): v2.12.
• VE.Direct MPPTs firmware: v1.29.
• Lynx Ion + Shunt firmware: v2.04.
• Lynx BMS firmware: v1.09.

CAN-bus Communication

The CAN-bus protocol is the primary method of communication between BlueNova batteries and Victron GX devices.

• Connection: The CAN-bus cable connects the BlueNova battery's RJ45 CAN-bus port to a VE.Can or "BMS Can" socket on the GX device.
• Termination: For BlueNova Energy "SSS" range batteries, a VE.Can terminator is not necessary for the other VE.Can socket on the GX device. However, RacPower (BP & DU) range BlueNova Energy batteries require CAN-bus terminations, which are supplied with each unit.
• Speed: The default CAN-bus speed for new BlueNova batteries is 500kbps. Some newer batteries offer selectable speeds of 250kbps or 500kbps. If you need to adjust the baud rate or configure a VE.Can port for BMS-Can, navigate to //Settings -> Services -> CAN-profile// on your GX device.

Distributed Voltage and Current Control (DVCC)

DVCC is a key feature for managing lithium battery charging and discharging in a Victron system.

• Activation: DVCC automatically activates when a BlueNova battery is connected via CAN-bus to a GX device running the required firmware (v2.12 or later).
• Functionality: It allows the GX device to control the charge and discharge parameters of connected Victron inverters and solar chargers based on information received from the battery's BMS.
• Configuration: You can enable or disable DVCC in the Settings → System Setup menu of your GX device.

Shared Voltage Sense (SVS)

SVS works in conjunction with DVCC to ensure accurate voltage readings across the system.

• Default State: SVS is enabled by default when DVCC is active.
• Adjustment: You can disable SVS in the Settings → System Setup menu if your specific system configuration requires it.

Multi-Battery Monitoring

For installations with multiple paralleled BlueNova Energy batteries, a BlueNova Energy BMAC Online unit can be used. This unit is installed between the BlueNova batteries and the Victron Energy GX device to allow monitoring of all individual batteries.
