50 Communication Options
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: Enables the connection of multiple devices (inverters/Commercial
Gateway) over the same bus, such that connecting only one device to the
Internet is sufficient to provide communication services for all the devices
on the bus.
RS485-2: Enables connection of multiple SolarEdge devices and of non-
SolarEdge devices over the same bus.
Wi-Fi
This communication option enables using a Wi-Fi connection for connecting to the
monitoring platform.
The Wi-Fi station is built into the inverter. An antenna is required and available from
SolarEdge for connection to the monitoring platform.
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
