Hi, we are also investigating the Modbus-Protocol of the Sermatec Inverter (in a Hycube System).
Our current status is summarized in this Excel spreadsheet (unfortunately mostly in English, but Google Translate can help):
https://github.com/xX-Overengineered-Xx/Hycube-PV-Research-Hub/blob/main/Sermatec%20SMT-5K-TL-LV/Modbus-Register%20(HY-5K-TL-LV).xlsx
In column "J" I have noted the values the Hycube Controller is writing into the Sermatec Inverter.
Maybe you can help to "decrypt" the not yet known registers.
0x3501
0x4046-0x404D
0x405B
0x405E
0x405F
0x4063-0x4065
0x4078
0x407B
0x40A1
0x4100
Thank you and best regards!
