I have integrated two SUN2000. First unit communication is not the best (sometimes it gonna show wrong values or zero but controlling commands work). Haven't diagnosed that if problem is in the network, dongle or inverter. With other one all works like a charm. Make sure that dongle FW is latest.
Here is register list for SUN2000.

Hello fleeceable,
Can you please share your modbus.json for the Huawei Sun2000 and battery system?
I will receive my PV system in a few weeks and would like to integrate it into my Schneider Homeylink.
Unfortunately I have never worked with Modbus.
