When modifying an existing installation, turn OFF the inverter ON/OFF/P switch, the DC Safety Unit (if applicable) and the AC circuit breaker on the main AC distribution panel.

  • Page 14: Installation Guidelines

      IMPORTANT SAFETY FEATURE Modules with SolarEdge power optimizers are safe. They carry only a low safety voltage before the inverter is turned ON. As long as the power optimizers are not connected to the inverter or the inverter is turned OFF, each power optimizer will output a safe voltage of 1V.

     2. To minimize electromagnetic interference (EMI), make sure to minimize the distance between the positive and negative DC cables. For detailed instructions, see: https://www.solaredge.com/sites/default/files/se-emi-performance- application-note.pdf.  3. Connect the rest of the power optimizers in the string in the same manner.

  • Page 19: Step 4: Verifying Proper Power Optimizer Connection

    Make sure the PV modules are exposed to sunlight during this process. The power optimizer will only turn ON if the PV module provides at least 2W. In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V hold different meanings from those in traditional systems.
