** Moved to a separate git repository, containing only this add-on.
Installing the add-on is a matter of putting the jar file under openhab/addons/ directory, replacing /usr/share/openhab/runtime/system/com/neuronrobotics/nrjavaserial/5.2.1.OH1/nrjavaserial-5.2.1.OH1.jar with https://github.com/dilyanpalauzov/nrjavaserial/releases/download/5.2.1-hidraw/nrjavaserial-5.2.1.jar and cleaning the OH cache. It is tested with openHAB 4.3 and 5.1.
As can be seen in the Readme file the only tried communication is by using USB cable, plugging the USB-B end in the inverter and the USB-A end on the openHAB-side. The Readme file describes also how to replace the nrjavaserial jar file from the openHAB distribution to make the communication work.

I hope this binding will be useful for all openHAB users with such hardware. I created this binding, as I wanted to transfer data from the inverter to openHAB in short polling cycles on low powered devices.
Updates of the add-on might change the channels structure and this would require writing transition files for things created over the UI. I do not plan to write such transition files, so either create the thing as a file in the openhab/things/ directory, or delete the thing from the UI before installing new version of this add-on.
