Problem Possible cause and troubleshooting

Pairing failed

Power optimizers are shaded.

If you connected the inverter to the monitoring

platform, retry pairing remotely (during

sunlight). Make sure to leave the inverter

ON/OFF switch ON and that S_OK appears in

the status screen.

String voltage is 0V

Power optimizer (s) output is disconnected.

Connect all power optimizer outputs.

String voltage not 0V but lower than

number of optimizers

Power optimizer(s) not connected in the string.

Connect all power optimizers

Module(s) not connected properly to power

optimizer inputs (not applicable to smart

modules).

Connect the modules to the optimizer inputs

String reverse polarity.

Check string polarity using a voltmeter and

correct if needed.
