I want to connect a BlueSolar MPPT 150/70 CAN and a BlueNova battery to a GX device. According to the BlueNova page on the VE site https://www.victronenergy.com/live/battery_compatibility:bluenova
Select the VE.Can & CAN-bus BMS (250 kbaud) CAN-profile in the CCGX. Menu path: Settings → Services → CAN-profile. Note that this changes the function of a VE.Can port: it is not possible to connect both VE.Can products and a Bluenova battery together.
Andre has informed me that I should use a Venus GX as it has 2 CAN bus ports. What is not obvious from the documentation on the web is which CAN bus port on the Venus GX to use with which device.
Also, the second CAN bus port only has a 3 way connector and is not isolated. Can a non-isolated port be used? What is the cable connection to the 8 way CAN bus port on the Battery or the MPPT?
According to this post: https://community.victronenergy.com/questions/19500/bluesolar-mppt-15085-can-bus-batrium-bms.html, the Venus GX cannot control the BlueSolar MPPT 150/70 CAN. If this is the case, then is there any merit in connecting it at all?
