RS485
RS485 is used for the connection of multiple SolarEdge devices on the same bus in a
leader-follower 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.
For connection instructions refer to Creating an RS485 Bus Connection on page 69.
The Wireless Gateway collects inverter data using a dedicated
Wi-Fi
The inverter connects to the Monitoring platform with via a home router. Wireless
Repeater(s) extend the Wi-Fi signal range between the Wireless Gateway and inverter.
Wireless Gateway and Wireless Repeaters can be purchased separately from SolarEdge.

Cellular
Cellular Plug-in (purchased separately) provides cellular communication to connect
one or several inverters to the Monitoring platform. Cellular communication depends
on the purchased data plan.
The Cellular Plug-in is provided with an antenna and user manual. Refer to
