Hello
I have a question about the voltage parameter between ground and PV installation. The Sun2000 8KTL M0 inverter indicates negative voltage on this parameter. Installation and construction are earthed. Equipotential connections done.
I do not know where the inverter reads this parameter, as only solar cables enter it from the PV side. At the end of production, voltage appears for a moment with a value of -1653V.
Screenshots are attached.
Best regards and thank you for any tips.

Hello, dear.
I checked out your screenshots. I think it's normal. The negative voltage in the picture should be the ground voltage. The inverter will provide a warning if there is any abnormality.
