Hello all,
 
In case is not too late and you didn't abandon the project I can confirm that the above protocol is the one used.
After many nights spent to reverse-engineering I was able to attach it to my Home Assistant and indeed it does use modbus protocol.
I wish I knew the protocol before starting to sniff the data send between the dongle and the invertor. Like that I didn't had to spend that many nights to discover what they "talk". Anyway I'm happy I was able to add it to my HA instance and now I can control it like it is with his own dongle. I was using a MAX3232 and an ESP8266 flashed with Tasmota (custom version to support ModBus). 
Also during the time I was sniffing the communication I also discovered that even the WiFi Dongle use the same ESP8266 chip. Now their dongle is flashed with that custom Tasmota firmware and I read the data via modbus-rtu with Home assistant.
With tasmota firmware you have two options:
      - one is just to read and show directly the needed values but this is just read only (at least this is what I was able to do).
     - the other one is to make it work with same tasmota via modbus-rtu over the network and the values you read directly with Home Assistant and this allowed me also  to change the modbus registers and this way can be controlled like with the original software/dongle.
Also after many days spent then I also find who made this model of inverter (from them I did get same file for protocol like the above). My finding (at least at that time) was that it is produced by JSD-Solar model Glory M5000 HHP-48. Now I don't see anymore on their website but if you search for the model name you can find it.
Mine is also from Easun but they didn't want to help me with the protocol.
Also on Easun it looks like that the model that have SMG in the name are the one with modbus protocol comunication. I did look in the manual of the new version (5.6KW) and I see is the same like mine and at the menu 25 is the parameter for the modbus Node ID the same like the older version at 5Kw.
