Hello - anyone out there having the specification for the APX battery MODBUS RTU protocol. I have tried to get it from Growatt with no luck, Or maybe some one has an idea how the register mapping is organized in the APX battery.
I am trying to connect a GroWatt MID 12KTL3-XH to a non Growatt Battery system via RS485. via a Rasperry PI ( rumning Node-Red) for protocol convertion between the inverter and the Battery RBMS ( a High Voltage 40 KWh battery).
I do have the GROWATT INVERTER MODBUS RTU PROTOCOL_Ⅱ Version 1.37 dated 2024.01.29 but it do not include the register mapping for the APX series
Any help will be much appreciated
Best Regards
