What to do if string voltage is lower than number of optimizers in SolarEdge SE33.3K Inverter?

If the string voltage of your SolarEdge Inverter is not 0V but lower than the number of optimizers, it could be due to several reasons. First, ensure all power optimizers are properly connected in the string. Second, verify that all modules are correctly connected to the power optimizer inputs. Lastly, check the string polarity using a voltmeter and correct it if necessary.
