As you can see on the picture, my proxy server for solar inverters works but I continously get this error mesage: "Is Not A Valid Memory Write Message To Server"
Any idea how to get rid of it?

with the help of Gemini I was able to fix the problem. The modbus write node puts its data directly into modbus-server. all I had to do was to delete the connection between modbus write and modbus server.
