i am a proud owner of a new PV-System with a “SUNNY TRIPOWER 8.0” Inverter. This one can communicate via Modbus. I am using the attached thing to communicate with the Inverter.
I am using Openhab 2.4 (and i am affraid to update it because most of the things are working fine)
Anyway the communication with the Inverter is also running fine most of the time, Openhab shows me the correct Power most of the time, but then all of a sudden, the shown power drops by the factor of 2 (approx) and then jumps back to the correct power after a very short while.
Does someone have an idea what the problem could be? Tbh, i am rather thinking of an EMI/EMC Problem on the line then on a software issue in Openhab, what do you think?
