Chapter 6: Setting Up Communication

Chapter 6: Setting Up Communication
The inverter sends the following information to the monitoring platform:
Power optimizer information received via the DC power lines (the PV output circuit)
l
Inverter information
l
Information of any other connected devices
l
This chapter describes setting up communication between:
the inverter and the monitoring platform through the Internet (wired/ wireless), or through a cellular
l
connection
multiple inverters f or a master/slave configuration
l
Communication setup is not required for power harvesting, however it is needed for using the
monitoring platform.
CAUTION!
When connecting the communication cables, make sure that the ON/OFF switch on the DC Safety
Unit is turned OFF, and the AC is turned OFF.
When configuring the communication parameters, make sure that the ON/OFF switch on the DC
Safety Unit is OFF, and the AC is turned ON.
ATTENTION!
Lors de la connexion des câbles de communication, assurez-vous que l'interrupteur MARCHE/ARRÊT
à la base de l'onduleur soit en position ARRÊT, et le CA est en position ARRÊT. Lors de la
configuration des paramètres de communication, assurez-vous que l'interrupteur MARCHE/ARRÊT
soit en position ARRÊT, et le CA est en position MARCHE.

Communication Options

The following types of communication can be used to transfer the monitored information from the
inverter to the m onitoring platform.
Only communication products offered by SolarEdge are supported.

Ethernet

Ethernet is used for a LAN connection. For connection instructions refer to Creating an Ethernet (LAN)
Connection on page 55.

RS485

RS485 is u sed 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 d evices, such as meters and third party
data loggers.
RS485-1: Enables the connection of multiple devices (inverters/Commercial Gateway) over the
l
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: The RS485 Plug-in provides an additional RS485 port for the
l
inverter for enhanced communications. The kit contains a module, which is
installed on the communication board, and has a 3-pin RS485 terminal block.
This kit is provided with an installation guide, which should be reviewed prior to
connection see,

For connection instructions refer to Creating an RS485 Bus Connection on page 58.
