I have multiple problems with my PV setup and it is unclear for me if that is caused by faulty hardware or just wrong values reported by the GoodWe integration for home-assistant. The e_day values look reasonable for that kind of setup and the PV technician has measured voltage values for all 4 strings while disconnected from the inverter. So i tend to believe that something is not correct with the values collected via ModBus TCP.
Problems
2 of the 4 PV strings report no power values, but voltage and current are reported
2 of the 4 PV strings report "PV panels not connected"
