The SolarEdge Key is a service tool that enables power optimisers with independent optimisation technology (IndOP™) to work with non-SolarEdge inverters without installation of an additional interface.
To ensure safe voltage during installation, all SolarEdge power optimisers are provided with the SafeDC™ feature enabled. When connected to a PV panel, these power optimisers 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 optimisers directly to a nonSolarEdge inverter without a Safety and Monitoring Interface, SafeDC must be disabled by the SolarEdge Key before connecting the string to the inverter.

Key Benefits:
- Fast, one time commissioning per string
- Can be used to enable safety voltage for the power optimisers during maintenance or other instances when DC safety on the roof is desired
- A portable and rugged handheld tool
- Can be used in multiple installations
