RS485 Surge Protection Device (SPD) Plug-in
The RS485 SPD is used for protecting RS485 communication lines against electrical
surges such as litghtning. The RS485 SPD is installed as a plug-in device directly on the
RS485 connector of the communication board inside the Tree Phase inverter and does
not requires to redo any RS485 wiring.
For installation and configuration of RS485 SPD, refer

AC Surge Protection Device (SPD)
The AC SPD is a device designed to protect the inverter from Voltage spikes and surge
attempts forming on the AC grid lines. The SPD limits the Voltage supplied to the
inverter by either blocking or shorting to ground Voltages above a safe threshold. The
SPD is installed inside the inverter and communicates with the SolarEdge Monitoring
platform for reporting surge protection events and faults.
For installation and configuration of AC SPD, refer to:
