BMS-Can is intended to be used with compatible managed battery systems, such as Pylontech, BYD, Freedomwon and many
more. These must be terminated at the Victron end (on the Color Control GX) with the included terminator (same one as used
with VE.Can). It may or may not be necessary to terminate at the managed battery, BMS or BMU - this will be documented in the
specific Victron Compatible managed battery instructions for that battery. Some batteries automatically terminate.
You can't mix VE.Can and BMS-Can on the same bus. If you wish to use both, they require a GX device with two seperate buses,
each with 2 RJ45 ports - 4 CANbus ports in total.
You cannot set BMS-Can ports to anything other than 500 kbit/s, and disabled.
You CAN set the VE.Can port from 250 kbit/s to be 500 kbit/s (or one of several other CANbus speeds for other CANbus
applications).
Other types of Batteries and BMS may claim compatibility with BMS-Can, or VE.Can, but if they are not on the battery
compatibility list then they have not been tested and confirmed to work by Victron.
One extra element of possible confusion is that there ARE some BMS products on the market that use a CANbus BMS profile at
250 kbit/s.
These can only be connected to the VE.Can port, and it must also be set to match this (VE.Can & CAN-bus BMS (250 kbit/s)) in
the services menu for the VE.Can port.
These BMS can be used in the same cable daisy chain as other Victron VE.Can devices.
2.3.5. BMV-600 series
Connect the BMV-600 using the VE.Direct to BMV-60xS cable. (ASS0305322xx)
2.3.6. DC Link box
, using the RJ-12 cable supplied. Then connect the BMV-700 to the CCGX - see connecting BMV-700
for more instructions.
2.3.7. VE.Can Resistive Tank Sender Adapter
page and manual on our website
for details about the Adapter.
To connect a product with a VE.Can port, use a
UTP cable.
Don't forget to terminate the VE.Can network on both ends using a
. A bag with two terminators is supplied with
each VE.Can product. They are also
(ASS030700000). (Available with straight or elbow connectors.)
Make sure that the CAN-bus is powered, see the
Power chapter in the Tank Sender Adapter manual
for details.
2.4. Connecting a PV Inverter
Measuring the output of a PV Inverter will provide the user with an overview of both actual power balance and the energy
distribution. Note that these measurements are only used to display information. They are not needed, nor used, by the
installation for its performance. Besides monitoring, the GX device can also curtail some types and brands of PV Inverters, ie.
reduce their output power. This is used, and required, for the
Direct connections
