6.2 Optional communication
Optional communication modes include Ethernet, which also needs corresponding communication parts and
components. All operation parameters of the inverter will be transferred through RS485 port, and then to the
communication devices. These allow the transfer of the monitoring data to the monitoring system (Web Portal / App).
If you need further information on optional communication possibilities, please contact the AEG technical service.
