Wrong data for SG10RT

[Razor094]

Hello, I want to transfer the PV data from my SG10RT via Modbus to Home Assistant. This has worked so far quite well, but I am not all data displayed, although in the Sungrow Winet module have connected via LAN cable. I have followed these instructions but I have a SG10RT.
My problem is that I do not get all the data displayed or the values do not match the cloud-data. For example, when I look at the daily or total production. There are completely different numerical values indicated which seem to represent a different measured value. Can someone help me here to find the correct measured values?

hi,

I updated the main readme file with a photo. Please check it :)

Everything will work, if you are using the internal LAN port as depicted in the photo.

if you use the LAN Port of the WiNet Stick several values won't work. The reason behind this, is that the WINET-S implementation of modbus is different to the internal LAN ports implementation. Also its kind of buggy. Unfortunately, we cannot fix these issues, only Sungrow can :/

Wow, very quick reply thanks for that.

OK then I think this would be a bigger issue for me because I am using not hybrid design.

The SG series has only one lan connection for the Winer module.

There are different modbus registers between SG and SH Inverters, so you may have a look around in the discussions. In addition search for this document TI_20220927_Communication Protocol of Residential and Commercial PV Grid-connected Inverter_V1.1.48_EN.pdf (maybe / hopefully there is a newer one, for me it fits) and rewrite the registers in the modbus_sungrow.yaml

i.e. Phase A current
from
address: 13030
to
address: 5021

name: SG6 Phase A current
unique_id: sg6_phase_a_current
slave: !secret sungrow_modbus_slave
address: 5021 # reg 13031
input_type: input
count: 1
data_type: int16
swap: word
precision: 1
unit_of_measurement: A
device_class: current
state_class: measurement
scale: 0.1
scan_interval: 30
