The CCGX only has one available VE.Can port. It is not possible to connect both CAN products such as VE.Can MPPT (250 kbit/s) and an B-Box battery CAN-bus (500 kbit/s) together on the CCGX. As the BYD Battery MUST be connected, you will need to use the port for that. This will mean no data is collected from the VE.Can MPPT, nor can the CCGX control it. This means you are required to use the "Allow to Charge" | The CCGX only has one available VE.Can port.

+ | With GX devices that have two CAN-bus interfaces available (eg Cerbo GX and Venus GX), the VE.Can MPPT will remain connected to the VE.Can port, while the BYD CAN-bus cable should use the specific CAN-bus connections (H, L, GND), or BMS-Can ports. | ||

The CAN-bus connections are galvanically isolated at the BYD BMU. There is no issues using the non-isolated connection of the VGX. | The CAN-bus connections are galvanically isolated at the BYD BMU. There is no issues using the non-isolated connection of the VGX. |
