I have all the equipment to start trying to do this now, I believe that growatt actually communicates to the pylontech batteries over rs485 and not can-bus but I have the can hat module so I will be able to use rs485 and can, from reading a lot about people connecting actual pylontech batteries it's using the rs485 at 9600 and needs some dip switches changed and possibly some firmware updates on the inverter to get it to work. currently have my inverter to lead-acid but it doesn't always start charging the batteries unless they are below 50% as it thinks they are still full.
