RS485
RS485 is used for the connection of multiple SolarEdge devices on the same bus in a
master-slave configuration. RS485 can also be used as an interface to external devices,
such as meters and third party data loggers.
RS485-1: Connects to the internal EV Charger circuit. Use it also for
connecting external meters.
NOTE
RS485-1 is used for internal connections. If an additional
connection is required, use and RS485 Plug-in (see below).
RS485 Plug-in: Purchased separately, the RS485 Plug-in
provides an additional RS485 port (referred to as RS485-E) for
the inverter for enhanced communications. The plug-in is a 3
pin terminal block which is installed on the communication
board. This kit is provided with an installation guide, which
should be reviewed prior to connection see,

Cellular (GSM, CDMA)
This wireless communication option (purchased separately) enables
using a cellular connection to connect one or several devices (depending
on the data plan used) to the monitoring platform.
The GSM/CDMA Plug-in is provided with a user manual, which should be
reviewed prior to connection. Refer to

Communication Connectors
A communication gland with multiple openings is used for connection of the various
communication options. The table below describes the functionality of each gland
opening. Unused openings should remain sealed.
