Communication lost after a while

[tafx]

Hi, I would like to ask for a help.
My setup: 2pcs 12 kW Deye 3ph LV inverters in parallel, master connected via RS485 "Modbus" port to waveshare RS485 to ETH(B) converter, addon "dev".

Communication is working only limited time period. Usually 3 to 30 mins. After that I got timeout errors:
"09:50:17 ERROR OSError in callback read_deye_1: timeout reading 1 registers from 141; timeout reading 1 registers from 146; timeout reading 5 registers from 587; timeout reading 1 registers from 609; timeout reading 7 registers from 619; timeout reading 1 registers from 636; timeout reading 4 registers from 650; timeout reading 8 registers from 672 poll_need_to_read"

Addon restart helps to establish communication. Waveshare converter restart did not help.

Do you have any idea how to solve that?
Thanks.
