Appendix A: Errors and Troubleshooting Problem Possible Cause Possible Solution String voltage is higher than the number of optimizers WARNING! If the measured voltage is too high, the installation may not have a safe low voltage. PROCEED WITH CARE! A deviation of ±1% per string is reasonable. Si la tension mesuree est trop haute, la tension basse de securite pourrait manquer dans l’installation. REDOUBLEZ DE PRECAUTION. Une deviation de ±1% par string est raisonnable. One or more extra power optimizer are connected in the string Check if an extra power optimizer is connected in the string. If not – proceed to next solution. Verify that only power optimizers are connected in the string and that no module A module is connected directly to the outputs are connected without string, without a power optimizer. a power optimizer. If the A malfunction of one of the power optimizers problem persists, proceed to the next step. o o o Disconnect the wires that connect the power optimizers in the string. Measure the output voltage of each power optimizer in order to locate the power optimizer that does not output the 1V safety voltage.If a malfunctioning power optimizer is located, check its connections, polarity, module, and voltage. Do not continue before finding the problem and replacing the malfunctioning power optimizer.If a malfunction cannot be bypassed or resolved, skip the malfunctioning power optimizer, thus connecting a shorter string.

Power Optimizer Troubleshooting Problem Possible Cause Possible Solution SafeDC mode was previously disabled using the SolarEdge Key Enable the SafeDC using the SolarEdge Key. Pairing to the inverter failed The power optimizers are shaded If you connected the inverter to the SolarEdge monitoring portal using one of the communication options, you can perform pairing remotely. Before leaving the site, make sure that the inverter ON/OFF switch is ON and S_OK indication appears on the LCD to indicate connection to the monitoring portal. 80 SolarEdge-Installation Guide MAN-01-00057-3.1
