Resolved after improving the earthing and switching the + / - wires.
With defective earth, no data was received the correct +/- wiring, and \x00 was received with the incorrect +/- wiring leading me to think the incorrect way was the correct way but I wasn't sending the right modbus commands.
Hello,
I've tried this code, but it fails as my inverter is just returning a 2 byte \x00 response.
Would you happen to have any idea what this might signify?
