Victron VE.Can to CAN-Bus BMS type A Cable 1.8m
CAN-bus Wiring
You can connect multiple battery modules together to form a single large battery by connecting the RJ-45 cable supplied by Pylontech using the link ports on the battery. This is shown in more detail in the example wiring diagram and Pylontech manual.
The communications for UP2500 can be paralleled up to 20 modules per string (and cannot use the LV-HUB). Other models can connect up to 8 battery modules (see Pylontech data sheets), in those models when using more than 8 parallel units, some limitations, additional configuration or equipment (e.g. Pylontech LV-Hub) may apply. See your Pylontech dealer, and Pylontech documentation for more details.
The batteries will automatically detect and link to each other, no adjustment of dip switches on the battery module are necessary.
The battery with the empty link port 0 is the master battery.
Type A cable
The Victron VE.Can to CAN-bus BMS type A Cable, part number ASS030710018 is used for connection with US2000C / US3000C / UP5000 / US5000 / US5000B / Force-L, BYD B-Box.
Type B cable
The Victron VE.Can to CAN-bus BMS type B Cable, part number ASS030720018 is used for connection with US2000 / US3000 / UP2500, LG Chem Resu, AXIstorage, BMZ, Pylon Batteries to BMS;
Note you cannot use the comms cable supplied by Pylontech for this connection between the master battery and the GX device.
Connections
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.

Off-Grid and Backup
The presence of a functional electricity grid is not always as obvious as it would seem to be. An insufficient infrastructure is often the cause for an unreliable grid. Things become even more difficult when there is no grid at all. And yet you are in need of a reliable electricity supply. A local and properly functioning system is the only answer at this point. Victron Energy offers you such an answer. We are proud to offer you our modern translation for freedom and independence. Energy, Anytime, Anywhere

Energy Storage
As more solar and wind power comes on line, it becomes increasingly difficult and expensive, to ensure stability of the grid. Intermediate energy storage is therefore rapidly becoming an essential tool to keep power fluctuations on the grid within manageable limits. Moreover, as feed-in tariffs are decreasing, the business case for a home energy storage system that increases self-consumption becomes more solid every day. Intermediate energy storage increases self-consumption of harvested solar and/or wind power. The natural next step is 100% self-consumption and independence from the grid.
