Abnormal injection voltage of solar inverter

Troubleshooting Solar Inverters: A Must-Read Guide to Repair

If the input voltage is abnormal, check the connection of the solar panels; if the output voltage is abnormal, restart the inverter to see if the issue resolves.
Technical Information

The inverter disconnects from the utility grid for safety reasons and/or fails to connect during self-test mode. The cause is often defective insulation or a faulty plug connection on the PV modules or within
DC injection the new source of trouble | Fluke

The low network impedance of an AC network means that a small DC voltage from the grid connected inverters creates a large DC current injection. This DC
Inverter reporting DC voltage too high

Can anyone suggest why the panels would now appear to be outputting a much higher DC voltage than they''re rated for? There is another thread with a possibly similar issue that
