Lightning and other surge events are unpredictable and can destroy an unprotected inverter in a moment. The RS485 Surge Protection Device 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, including the E-Series. 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 RS485 Surge Protection Device has a 9-pin connector block, which can be used for connecting RS485 devices instead of connecting to the unprotected communications board.
The RS485 Surge Protection Device is Class II SPD and complies with UL497A / IEC 61643-21*. It was tested and has shown the ability to withstand multiple surge events.
