This integration lets you gather sensor data and control the EMS (Energy Management System) of a wide range of Sungrow inverters, including, but not limited to: SH3.6RS, SH4.6RS, SH5.0RS, SH5.0RT, SH6.0RS, SH8.0RT, SH8.0RT-V112, SH6.0RT, SH10RT, SH10RT-V112, SH5K-20, SH3K6, SH4K6, SH5K-V13, SH5K-30. A battery is not required, but several sensors will not be available without one.
If avaliable, ensure, that you connected the inverter to the Home Assistant network using the internal LAN port. The WiNet Ethernet port and the WiNet WLAN are only partially working and we cannot fix this! (sungrow winet programming ==> no support, sorry :/ )
The documentation covers following topics:

I have a Sungrow SH10.RT Inverter and a PylonTech Force H1 battery with 14.4 kWh updating frequently to the latest Home Assistant (> 2023.3). I try to thoroughly test features before releasing them, but I cannot test everything (e.g., backup capabilities, DO-related, ...)
The Modbus register mapping is based on two documents the Sungrow support sent me (my current version is v1.0.25 from 12.01.2023. The changelogs from .23 to .25 only mention added device codes (*RT-20, *-V112 and *-V122). I am not sure if I am allowed to share the files, but you can search for them using their names. Let me know in the github discussions, if there are newer versions available.

Please let me know if the integration also works with other Sungrow models.
Community-confirmed supported inverters (thank you for reporting!)
- SH10RT (via home assistant community, brix29 Axel)
- SH10RT-V112 (github, dzarth, ViktorReinhold)
- SH5.0RT(home assistant community, ptC7H12 Paul)
- SH8.0RT (github, lindehoff)
- SH5K-30 (github, ajbatchelor)
partially working
- SH5.0RS (home assistant community, Danirb80) via WiNetS: register running_state is not available. Created workarounds using template sensors
- SH6.0RS (github, icefest) largely working, occasionally needing to restart the winet
- See #38 for some kind of a roadmap
- I included the registers, which are common between a wide range of Sungrow inverter models. There are many more registers in the Sungrow documents, which I left out, but I am happy to include them, if you need them. --> github discussions
- If you made a nice visualization - let us know! --> github discussions
- This is meant to be a simple, straightforward YAML-based integration. If you need more than this, I recommend having a look at the SunGather project: https://github.com/bohdan-s
We are happy to share our experiences - feel encouraged to share yours with us, too!
