Since I am currently double checking every value my Sungrow Inverter reports this is appreciated!

The newest revision I have found is 1.1.5:
TI_20240924_Communication Protocol of Residential Hybrid Inverter-V1.1.5-1.pdf (422.0 KB)

However, after the latest firmware update I noticed that register 13022 Battery Power is now reported as S16. In this document it is still labeled U16. Is there any reliable source for the latest revision of this document?

Hi,

I’m new to this forum, being generally interested into Smart Home topics and specifically for accessing my Sungrow SH10RT-v112 inverter via Modbus. For this I am looking for a documentation of the Sungrow modbus registers and came across this thread, but I am not able to download any of the PDF files here. Are there other sources except of the Sungrow support for this document?

Thanks a lot for any help and best regards,

Schorsch

Hmmm…I can’t open this one either - it says “Oops! That page doesn’t exist or is private.”
Anyone know how to fix that please?
