4.4 Communication Connection
Inverter operation data can be transferred by RS485, or WIFI Modular to a PC with monitoring
software or to data logger device such as Ezlogger Pro. RS485 is the standard communication
choice for inverter, and WIFI modular can be used optionally for communication.
You can refer to EzLogger Pro SERIES USER MANUAL. Visit

4.4.1 RS485 / DRED / Remote Shutdown Communication
The RS485 port of inverter is used to connect the EzLogger Pro, and the total length of connecting
cable should not exceed 1000m.
DRED is only for Australian and New Zealand installations, in compliance with Australian and New
Zealand safety requirements. DRM function is achieved by Ezlogger Pro or DRED COM port.
Please connect the Ezlogger Pro to the RS485 port.
For detailed DRED connection instructions, refer to the Ezlogger Pro manual.
Remote shutdown is only for European installations, in compliance with European safety
requirements. A remote shutdown device is not provided by manufacturer.
DRED should be connected to the COM port with 6-Pin and remote shutdown to the COM port
with 2-Pin as illustrated below.
