true for Victron Energy lithium batteries with the VE.Bus BMS, the Lynx Ion + Shunt BMS or the Lynx
Ion BMS. DVCC is the preferred operating mode for Redflow ZBM2/ZCell batteries using the Redflow
CANBus BMS.
Firmware versions
Do not use DVCC in cases where these requirements are not met. In all cases we recommend to
install the latest available firmware during commissioning. Once running well, there is no need to pro-
actively update firmware without reason. In case of difficulty, the first action is to update firmware.
Required minimum firmware versions:
Multi/Quattro: 422
MultiGrid: 424
CCGX / Venus GX: v2.12
VE.Direct MPPTs: v1.46
VE.Can MPPTs with VE.Direct: v1.04
Older style VE.Can MPPT Solar Chargers (with the screen) cannot be used: they do not support
the new control mechanisms.
Lynx Ion + Shunt: v2.04
Lynx BMS: v1.09
From Venus firmware v2.40, there will be a warning message 'Error #48 - DVCC with incompatible
firmware' when one of the devices has an incompatible firmware while using DVCC.
In case of an ESS System, the ESS Assistant needs to be version 164 or later (Released in November
2017).
4.3 DVCC effects on the charge algorithm
Our inverter/chargers and MPPT Solar Chargers use their own internal charge algorithm when in
stand-alone mode. This means that they determine how long to remain in Absorption, when to switch
