Huawei SUN2000 6KTL-L1 modbus communication

I have a Huawei SUN2000 6KTL-L1 Solar Inverter, and I like know the protocol data with the 485 line.
I would like to connect a std battery to the huawei inverter. To do this I would have to reply to the inverter the data of a battery.
I should simulate a battery connected to the inverter.
Anyone have trace data with battery connected?
if there was someone who wants to do this test and study together…
many thank
