This equipment has been tested and found to comply with the
limits applied by the local regulations. These limits are
designed to provide reasonable protection against harmful
interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, you
are encouraged to try to correct the interference by one or
more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and
the receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV
technician for help.

Chapter 1: Overview
The RS485 provides an additional RS485 port (sometimes
referred to as RS485-E) for the inverter and the Commercial
Gateway. The kit contains a module which is installed on the
inverter or Commercial Gateway communication board and
has a 3-pin RS485 terminal block.
The RS485 module allows connecting the inverter directly to
3rd party monitoring systems (Modbus master) or various
Modbus slave devices such as batteries and meters, in addition
to other inverters. This second RS485 port also enables nested
RS485 networks, valuable when setting up a communication
network for large sites.
NOTE
When using the RS485 module, the ZigBee and Wi-Fi
wireless communication options cannot be used.
A multiple inverter system can be connected to meters, 3rd
party gateways and other devices with the additional RS485
port.

RS485 Configuration to Master
SolarEdge protocol configuration is supported on all RS485
buses simultaneously. The inverter/Commercial Gateway can
be:
Master on one bus and slave on the other
Master on both buses (dual master)
Slave on both buses
RS485 Expansion Kit Installation Guide MAN-01-00258-1.0
17 RS485 Configuration to Master
The RS485 enables the connection of up to 16 RS485 buses
with up to 32 devices each in a daisy chain configuration for
communications in commercial installations.
To configure RS485 communications of the additional
bus:
1. If the master device is an inverter - verify that the inverter
ON/OFF switch is OFF.
2.
Turn ON the AC to the inverter/Commercial Gateway.

2.
If after slave detection the number of slaves displayed in
the master under RS485-X ConfèSlave Detect is smaller
than the actual number of slaves, use one of the following
methods to identify missing slaves and troubleshoot
connectivity problems:
Use the Long slave Detect to retry
connecting to slaves
Analyze the Slave List to check for
missing slaves, and check their
connection
