IMPORTANT SAFETY FEATURE:
Each power optimizer is equiped with a SafeDC mechanism which ensures the optimizer outputs a
safe 1V voltage until connected to the SolarEdge inverter or SMI, and the inverter/SMI are turned
ON.
When connecting the power optimizers to a non-SolarEdge inverter without a Safety and
monitoring Interface, you must disable the SafeDC before connecting to the inverter. Refer to the
SolarEdge Key manual for more information on how to disable the SafeDC
After disabling the SafeDC, opatimizers will always output the module voltage regardless of
inverter state.
The following table summarizes the safety considerations when using the power optimizers:
