Refer to the latest Discover Energy Systems documentation for battery values and the
latest Victron documentation for menu navigation and details on the setup procedure.
-
Set the Discover Lithium batteries to ON and the Victron GX device to ON.
-
Using a touch screen or other user interface of the GX device, set the VE.Can
port and CAN-Bus BMS communication rate to 250 kbit/s to match the
communication speed set up on the LYNK II communication gateway.
Device List > Settings > Services > VE.Can port > CAN-bus profile
• Select VE.Can & CAN-bus BMS (250 kbit/s)
(Select Victron solar inverters may operate with CAN-bus BMS 500 kbit/s)
CAN-bus profile
-
Return to the Device List, and the Discover Lithium Battery should now appear
as one of the devices.

If Discover does not appear on the Device List, confirm that the CAT5e or higher communication cable is a normal patch type, not a cross-over type. Use manufactured cables to avoid bad crimps and reduce the risk of a poor connection. |

To confirm that all batteries in the network are communicating with the Victron system, review the actual battery parameters. If multiple batteries are connected, a single entry shows the total limit of all the batteries.

Closed-loop Settings
During normal operation, the battery’s charge parameter limits are set by the BMS and communicated by the Victron GX device to the inverter-charger and MPPT.
To optimize the performance of a Victron system, manually set the following DVCC menu items using the Victron GX device and reboot the system.

Automatic Selection |
(1) Limit charge current works across the whole system. MPPTs are automatically prioritized over the mains. In cases where the BMS requests a maximum charge current different from the user-configurable setting, it uses the lesser of the two.
(2) SVS should be set to OFF (Victron support has reported instances of conflicts when SVS is set to ON with a Lithium BMS).
Saving Closed-Loop Settings
Device List > Settings > General > Reboot?
After all DVCC menu items have been set, reboot the system to complete the closed-loop configuration.
