What to do if my Hoymiles HYS-3.0LV-EUG1 Inverter indicates a PV Reverse Connection?

If your Hoymiles Inverter displays a PV Reverse Connection error, it means the PV strings are connected with reverse polarity. To resolve this: 1. Check if the corresponding string has reverse polarity. If so, disconnect the DC switch and adjust the polarity when the string current drops below 0.5 A. If the alarm persists, further assistance may be needed.
