According to Solis you can control power limit just like in the Solis Cloud app via the API. But I don’t understand the API data sheet.
*edit, found a Control API document.
https://oss.soliscloud.com/doc/SolisCloud_control_api_command_list.xlsx
I think we want to serve cid:15 “Power Limit Value”.
In the tester you can also generate the code. Choose controlSettings, CID 15, (hybrid mode off)
You will then get:
Request Constructor:

Content MD5 is something about encryption. And the second part of the API key looks like a checksum when I test multiple times. So this is way above my level. @Kim_Kokholm Is this information something you can work with? In connection with negative feed-in tariffs it would be very nice if we could get this working.
