Need help?
Do you have a question about the Aurora PVI-3.0-TL-OUTD and is the answer not in the manual?
Questions and answers
Error E031
Error E031 on the Power One Aurora PVI-3.0-TL-OUTD inverter indicates that the input channel operation mode selection switch is set to PAR (parallel), which may be incorrect. This can prevent the inverter from establishing a connection with the grid. To resolve this, check the status of the selection switch for the input channel operating mode and verify jumper settings between the input channels.
