    So I was able to pin down the one that’s not reporting. .swapped it to a different place in the string...did the whole thing repairing optimizers again ..and still it’s the same optimizer that’s failed to report to the inverter..my question is all of my others optimizers only shows anywhere from 0 to 5w but the failed one (panel 1.0.1 -1031A661-48) is showing 48.49 power (w) from Solaredge monitor please see pix I also included a few samples of the normal working optimizers . Can anyone pin point how ..why what wrong or just a failed optimizer ..or how do I resolve this.. much help is appreciated. Btw it’s 7:00 am here in Texas (no sun) right now. Thanks

    It's possible the optimizer has failed. If you shut the inverter off, what voltage do you read at the DC terminals? If it is not 18V, the optimizer is bad and will need to be replaced.
    The high power reading with no sun leads me to believe it is faulty, and is reporting bad information.
