Lightning and other surge events are unpredictable and can destroy an unprotected inverter in a moment. The surge protection device plug-in from SolarEdge, is designed to protect the inverter's RS485 transceiver in cases where surge events might occur. The small and inexpensive device is compatible with all SolarEdge three phase inverters. It snaps into the RS485 terminal via the 9-pin connector and a single cable is connected to the inverter with a grounding screw. The surge protection device plug-in has a 9-pin connector block, which can be used for connecting RS485 plug-ins instead of connecting to the unprotected communications board.
The surge protection device plug-in is a Class II SPD and designed according to UL497B / IEC 61643-21. It was tested and has shown the ability to withstand multiple surge events.
