Power Optimiser Troubleshooting 

Malfunction

Possible Cause and Corrective Action

Pairing failed

Power Optimisers are shaded.

If you connected the inverter to the  monitoring 

platform, retry pairing remotely (during 

sunlight). Make sure to leave the inverter 

ON/OFF/P switch ON and that S_OK appears in 

the status screen.

PV string Voltage is 0V

Power Optimiser (s) output is disconnected.

Connect all Power Optimiser outputs.

PV string voltage not 0V but lower 
than number of Power Optimisers 

Power Optimiser(s) not connected in the PV 

string.

Connect all Power Optimisers.

Panel(s) not connected properly to Power 

Optimiser inputs (not applicable to smart 

modules).

Connect the modules to the Power Optimiser 

inputs.
PV string reverse polarity.

Check PV string polarity using a voltmeter and 

correct if needed.
