Describe the issue

I am always getting the following error after a few minutes of successfully connecting and getting data of the inverter

Logger: custom_components.must_inverter Source: custom_components/must_inverter/init.py:211 Integration: Must Inverter (documentation, issues) First occurred: February 1, 2024 at 11:26:30 PM (8555 occurrences) Last logged: 1:23:45 PM

I have used different methods and different adaptors, but getting the same issue When i reload the integration, it fixes it for a few minutes, then stops again so I have to reload the integration again

I have made an automation to automatically reload the integration when getting this error from the log

I have a must PV1800 3k inverter, now connected through the RJ 45 port to a USB to RS485 Converter Adapter then to my HA instance

Reproduction steps

1. Successfully connected to the inverter via RS485 and serial 2.After a few minutes, i get the error reading modbus data at address 20001 etc 3.have to reload the integration for it to pull data again from the inverter ...
