Monitoring surge arresters (S2X versions only)
The inverter monitors the status of the surge arresters (both AC and DC)
and generates a warning in the event of a fault (visible on the display).
Data transmission and control
The inverter or networks of several inverters can be monitored locally or
remotely using an advanced communication system based on a RS-485
serial interface that can be congured to communicate using the proprie-
tary “Aurora” or public “ModBus RTU” protocol (PMU RS485 port).
