Hi @wudycool,

maybe this is of help for you: https://community.victronenergy.com/questions/97434/ccgx-with-two-canbus-inputs.html

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

AFAIK the battery requires the canbus speed set to 500kbit/s, which makes it impossible to daisy chain with your MPPT (VE.Can 250kbit/s). Either you change to a Cerbo GX (two independent canbus ports) or connect your MPPT via VE.Direct to your CCGX.

@wudycool
Old model VE.Can MPPTs are not supported.
See below paragraph from the Pylontech compatibility manual:

MPPTs with a VE.Can port

New Model (2019 and later) VE.Can MPPTs are also supported from firmware version 1.06 and above. Be aware that some GX devices (e.g. CCGX) only have a single CANBus interface, and that is required for the battery communications. So if you use a new VE.Can MPPT, it must also be with a GX device that has more than one CANbus interface, e.g. the Cerbo GX.

Old model VE.Can MPPTs (pre 2019) are not supported.
