Why has pairing failed on my SolarEdge SE100K Inverter?
If pairing failed on your SolarEdge Inverter, it might be because the power optimizers are shaded. If you connected the inverter to the SolarEdge 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.
Why is the string voltage higher than the number of optimizers on my SolarEdge Inverter?
If the string voltage of your SolarEdge Inverter is higher than the number of optimizers, it could be due to several reasons. First, check if an extra power optimizer is connected in the string. If not, verify that only power optimizers are connected in the string and that no module outputs are connected without a power optimizer. In addition, a power optimizer might be malfunctioning: disconnect the wires connecting the power optimizers in the string and measure the output voltage of each power optimizer to locate the one that does not output 1V safety voltage. If a malfunctioning power optimizer is located, check its connections, polarity, module, and voltage. Contact SolarEdge Support if needed, and do not continue before replacing the malfunctioning power optimizer.
What to do if the string voltage is lower than the number of optimizers in my SolarEdge SE100K?
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. Ensure all power optimizers are connected in the string. Also, check that the modules are properly connected to the power optimizer inputs. Finally, verify the string polarity using a voltmeter and correct it if needed.
How to fix a 0V string voltage on my SolarEdge SE100K?
If the string voltage of your SolarEdge Inverter is 0V, it indicates that the power optimizer output(s) are disconnected. Connect all power optimizer outputs to resolve this issue.
