Victor Max 10.2 Kw rs-232 protocol

[elproko]

I did search here (and uncle Google) but with no luck...

I try to search for rs-232 protocol for this inverter. I successfully sniffed traffic between wifi dongle and inverter but I cannot find anything about data I received.

Maybe You discover something from it?

Partially it seems like modbus (05 at the beginning is my inverter's ID)

It is 2400 baud only, 8, N, 1:
from dongle to inverter:

First field is time stamp.
Note: queries and responses have different timestamps as I could only sniff one side at a time.
So these are two separate "sessions" initiated by powering up the WIFI dongle each time

Any help here?

Attached timely synchronised traffic (sniffed two ways) showing events after attaching wifi dongle. (dongle_turn_on.txt)

Also former de-synchronised files.
