Surge Protection Device Plug-in

Lightning and other surge events are unpredictable and can destroy an unprotected inverter in a moment. The surge protection device (SPD) plug-in is designed to protect both RS485 communication buses of SetApp-enabled three phase inverters(1) in cases where surge events might occur.

Small and inexpensive, this SPD easily snaps into the inverter’s RS485 terminal block via the 6-pin connector. It’s also ideal for existing installations, as it can be connected without having to redo the RS485 wiring.

The SPD plug-in meets the IEC 61643-21 and EN 61643-21 standards and has shown the ability to withstand multiple surge events during testing.
