We still see inv_no_response when sending your inverter instructions. Can you check and see if you can do this via the Growatt web dashboard? https://server.growatt.com
And see if you can set Battery First time there For Time Period 1 and Save (Click the blue Yes button). Use password: growatt20251216 - making sure you change for the current day, the numbers are yyyyMMdd.
I suspect that will throw an error too, in which case you can contact Growatt.
