A clear and concise description of what the problem is.

I have MUST inverter ph1800 Model 3024 plus RJ45 with RS485 interface. I tried to create a converter but it doesn't work with my inverter. Although its performance is similar to those on which these converters work. I made a request to the developer and they sent me the file with RS485 Modbus RTU communication Protocol (Attached here) And other information that I have PH1800 PV1800 EP1800 PV3500 EP3500 RS485 Modbud RTU communication Protocol1.4.15&nbsp_ 20180901.xlsx must_ph18_3024_plus_manual.pdf must_ph18_3024_plus_pasport.pdf must_ph18_3024plus_datasheet.pdf

Additional context

In addition, I want to say that I managed to connect the inverter to the Home Assistant via the USB-B cable, but the connection is unstable. The integration can work for 2-3 hours and stop collecting data from the inverter until the Home Assistant is completely restarted. Here is link on that integration: https://github.com/mukaschultze/ha-must-inverter
