Hi,
Are you sure that this is a inverter of 1st generation, regarded to the name should it be an 2’nd generation inverter?
If so, shall you use the Kostal 10-20 part of inverter and configuration as: ( mine is without battery, so just Please try with Inverter Type with battery )
Another thing you can try is to in an Web-browser do like:
http://‘Inverter-IP’/api/dxs.json?dxsEntries=83888128 //Self Consumption
http://‘Inverter-IP’/api/dxs.json?dxsEntries=83886336 //Home Consumption PV
http://‘Inverter-IP’/api/dxs.json?dxsEntries=83886592 //Home Consumption Bat
http://‘Inverter-IP’/api/dxs.json?dxsEntries=83886848 //Home Consumption Grid
then should you get the value back for each dxsEntries.
Please try, and let me know!!
