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 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,
