Power Optimizer Troubleshooting 

If the inverter status screen indicates that not all power optimizers are 

paired or not all are reporting (P_OK xxx/yyy, and x<y), those optimizers 

can be identified through the LCD. Refer to 

https://www.solaredge.com/sites/default/files/non_reporting_power_

optimizers.pdf

Malfunction

Possible Cause and Corrective Action

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.

Panel(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.
