question

I'm using Modbus TCP with Home Assistant.

Take this for refference

Here are the Unit IDs and Addresses for your counters:

Unit ID 227 Address 76 "Energy from AC-In 1 to battery"

Unit ID 227 Address 80 "Energy from AC-In 2 to battery"

Unit ID 227 Address 92 "Energy from AC-out to battery (typically from PV-inverter)"
