numbers and wifi codes.
GX Error #47 - Data partition issue

GX Error #48 - DVCC with incompatible firmware
This error is raised when the DVCC feature is enabled whilst not all devices in the system are updated
to recent enough firmware. More information about DVCC and minimal required firmware versions in
chapter 4 of this manual.
Note for systems with BYD, MG Energy Systems, and Victron Lynx Ion BMS batteries:
Since Venus OS v2.40, released in December 2019, the DVCC feature is automatically switched on in
case the systems detects one of mentioned battery/BMS types connected. And it is not possible to
switch DVCC off in that case.
This creates an issue for systems installed and commissioned a long time ago, from before DVCC was
available and later due to mandatory work for such systems.
The solution is to:
1. Disable automatic updates; Settings → Firmware → Online updates.
2. Roll back to v2.33; See Settings, Firmware and then Stored backup firmware.
3. Make sure that DVCC is disabled again.
Please do consult your installer, to check if the battery system is managed with two wire control (no
DVCC needed) or not:
In case there is no charge- and discharge- wiring between BMS, inverter/chargers and charge
controllers, then DVCC is required for the above mentioned battery brands, and this also has certain
minimum firmware requirements for connected Inverter/Chargers and Solar Charge Controllers.
Whats new since Venus OS v2.40 is (a) that it automatically enables DVCC when it sees the above
mentioned battery types, and (b) that when DVCC is enabled, it checks the connected devices for the
minimum firmware, and raises Error #48 in case the firmware of one or more connected devices is
too old.
