Plug the communication cable with the side which is labeled Battery BMS into the Pylontech CAN port
of the master battery.
Some GX devices (such as the Cerbo GX), have multiple CAN ports. If your GX device has a BMS-Can
port, this should be used. If your GX device ONLY has VE.Can ports, you will need to change the
VE.Can port profile to CAN-bus BMS (500 kbit/s) for the battery (and then it cannot be used for other
VE.Can devices).
Plug the side labeled Victron VE.Can into the GX device.
Then, plug a VE.Can terminator in the other VE.Can socket on the GX device. Two VE.Can terminators
are included with the package of the GX device as an accessory, only one is used. Keep the other one
as a spare.
More information about the cable can be found in its manual.
Without properly connecting this cable, the battery will not show up on the display of the GX device.
The battery will also turn itself off.
It is important to ensure this connection and display of the battery on the GX device display before
attempting firmware updates or settings changes on other devices if they depend on the power
supply from the battery. Without this connection, the battery may turn off unexpectedly.
4. GX Device Settings
When the Pylontech battery is connected to the BMS-Can port of a GX device (running v2.80 and
later) the following DVCC settings will be set and enforced automatically.
If you are running a GX firmware version prior to this, these will need to be manually configured.
Manual Configuration
On the GX device,
If your GX device has a BMS-Can port, the battery should be connected to this.
If you connect the BMS to the VE.Can port you will need to adjust the port speed. Select the
CAN-bus BMS (500 kbit/s) CAN-profile in the GX device. Menu path: Settings → Services →
VE.CAN port.
After properly wiring and setting the correct CAN-bus speed, the Pylontech will be visible as a battery
in the device list. If you have multiple batteries a single entry will show up, which represents all
batteries:
