      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.

      Step 3: Connecting Power Optimizers in Strings Connect the Minus (-) output connector of the module to the Minus (-) input connector of the power optimizer. Figure 3: Power optimizer connectors Step 3: Connecting Power Optimizers in Strings You can construct parallel strings of unequal length, that is, the number of power optimizers in each string does not have to be the same.

  • Page 20: Step 4: Verifying Proper Power Optimiser 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 poweroptimizers 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.
