I found a solution to compile a version which can be tested locally with the help of:
https://community.openhab.org/t/openhab-5-x-snapshot-requires-java-21/160890
You find the new version at:

I have added the registers 1016 … 1019 in the heat pump thing and a new channel Actual power signed in the general section.
The registers 1016 … 1019 do not show reasonable values in my setting.
@Agio: Try using the new Actual power signed to work with PV-surplus. Did you try to work with Actual power directly? It might work too or do you get an error?
The binding is compiled for 5.0.0 but with Java 17 and works in my setting.
You have to copy it to your addons-folder, restart openhab and create new things. I could use the existing 4.3.0-things parallel to the new 5.0.0-things.
I plan to add the registers 3004 … 3009 next week - too much other stuff to do…
