    SolarEdge inverters. Power optimizers with P/N starting with "OPI", “OPJ” or “PxxxI” have the IndOP™ feature. Each power optimizer transmits its module’s performance data over the DC power line. When using a SolarEdge inverter, these signals are received by the inverter and can be used for maintenance and remote monitoring.

    Make sure the modules are exposed to sunlight during this process; otherwise, the power optimizers may not be powered. If you use a tracker, the power optimizer will turn ON only if the tracker is tracking the sun and at least 2W are provided by the module.

    SolarEdge power optimizers are provided in a SafeDC mode: when connected to a PV module these power optimizers will output a safe voltage of 1VDC until they are paired either with a SolarEdge inverter or with the SolarEdge Safety & Monitoring Interface, and until power production has started.

    Chapter 3: Power Optimizer Installation Disable the SafeDC (refer to the SolarEdge Key User Manual (http://www.solaredge.com/groups/support/downloads) The SafeDC mode is now disabled and the voltage of each power optimizer equals the voltage of the module (Voc). WARNING: The DC cables carry a high voltage and the power optimizers no longer output a safe 1V output.
