Victor NM-II 5.0KW question about changing the protocol version

[audito67]

Good afternoon.

I have an inverter, Victor NM-II 5.0KW, I tried to get data from it using an interface converter and esp8266 with the firmware of this project. The inverter is not sending data. I checked the protocol version using esp8266-test-protocols.yaml and it turned out that reading is possible using the following protocol (Testing PI30/PI30MAX/PI30REVO/PI41 commands...
This is the set of commands supported by the pipsolar component!).
Question, tell me how to change the protocol version in the main program (firmware) so that data can be exchanged between the inverter and esp8266 (Home Assistant)?
I am contacting you here because on the main page of the project it is indicated that if you have difficulty interpreting the protocol, contact the community.
Thank you in advance for your understanding and support.
