I have 2 SmartSolar MPPT chargers connected to a Cerbo GX and plan to communicate to the Cerbo GX via CAN bus from a custom controller. The Technical-Information-Data-Communication-with-Victron-Energy-products_EN document has a section on Canbus PGN overview per product but I don't see the Cerbo GX listed (or the SmartSolar). What standard CAN messages can I expect to see and what are the PGNs? Thanks.
