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.

(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).
