SolarEdge Key

The SolarEdge Key is a service tool that enables SolarEdge power optimizers with independent optimization technology (IndOP™) to work with third-party inverters without installation of an additional interface.
To ensure safe voltage during installation, all power optimizers are provided with the SafeDC™ feature enabled. When connected to a PV module, these power optimizers 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.

When connecting PV strings with power optimizers directly to a third-party inverter without a Safety and Monitoring Interface, SafeDC must be disabled by the SolarEdge Key before connecting the string to the inverter.
