In order to ensure mechanical compatibility of the SolarEdge optimizers and the modules to which they are connected: ...
- Page 7 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 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.

Page 8: Chapter 2: Introducing The Solaredge Power Optimizers
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. To monitor the modules when using a non-SolarEdge inverter, add a SolarEdge Safety and monitoring interface device (purchased separately). -
