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.
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
