Emission Compliance
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.

2 Emission Compliance

Changes or modifications not expressly approved by the party
responsible for compliance may void the user’s authority to
operate the equipment.
NOTE
Interferences may occur when the Wi-Fi Gateway and
repeater are installed near other 2.4 GHz emitting
devices (such as dual technology PIR detectors used in
alarm systems, microwave ovens, etc.). This might
degrade/ disable the gateway/ repeater operation. If
possible, avoid installation nearby such devices, or
consider these interferences when troubleshooting.

8 About This Guide

Chapter 1: Overview
The Wi-Fi communication option enables connecting a
SolarEdge inverter to the SolarEdge monitoring platform. The
Wi-Fi Gateway collects all inverters monitoring data using
dedicated Wi-Fi and connects to the monitoring platform
through Ethernet.
The Wi-Fi connection between the gateway and the inverter is
independent ("walled garden"), thus avoids problems related
to the home router, for example: changing the passwordwill
not affect the PVsystem connection to the monitoring
platform.
A Wi-Fi access point is built into the inverter. An antenna
(included in the Wi-Fi Gateway package) connects to the
inverter. The Wi-Fi Gateway is connected to the home router
with an Ethernet cable.
SolarEdge offers two Wi-Fi products:
Wi-Fi Gateway - provides the inverter connection to the
monitoring platform.
Wi-Fi Repeater(s) - one or two repeaters can be used for
extending the Wi-Fi range. The repeater connection to the
Wi-Fi Gateway and inverters is wireless and does not
require an Ethernet cable.
Wi-Fi Gateway and Repeater Installation Guide MAN-01-00559-1.1
Chapter 1: Overview 9

The Wi-Fi Gateway and repeater can be used with SolarEdge
inverters with SetApp configuration, version 4.6.xx and later.

Terminology
This document uses the following terms for describing the
communication flow:
Uplink - communication from the inverter or Wi-Fi
repeater to the Wi-Fi Gateway/repeater towards the
monitoring platform (see Figure 2 ).
Downlink - communication from the Wi-Fi Gateway or
repeater towards the inverter/ repeater (see Figure 2 ).

10 Connection Options

Single Inverter, Wireless Connection
The inverter is wirelessly connected to the monitoring platform
via the Wi-Fi Gateway. The Wi-Fi Gateway is connected to the
home router via Ethernet. One or two optional repeaters
extend the Wi-Fi range.
Figure 2: Single inverter, wireless connection
Multiple Inverters
Multiple devices, RS485 Master/ Slaves
Multiple inverters are connected in an RS485 bus. The master is
connected wirelessly to the Wi-Fi Gateway. The Wi-Fi Gateway
is connected to the home router via Ethernet. One or two
optional repeaters extend the Wi-Fi range.

Figure 3: Multiple inverters, wired connection
Multiple devices, Wi-Fi Point to Multi-point
This configuration enables connecting multiple devices
wirelessly. The Wi-Fi Gateway is connected to the home router
via Ethernet. Several inverters can be connected to a single Wi-
Fi Gateway. One or two optional repeaters can be used to
extend the Wi-Fi range.

Chapter 3: Connection and
Configuration
This section describes basic connection and configuration of
one or more inverters.
You can connect the inverter(s)using just the Wi-Fi Gateway.
However, one or two repeaters may be required to extend the
Wi-Fi range.
You can choose to delay the installation completion, in which
case the first configuration steps are performed by the
installer, and the home owner can later connect the devices to
electrical outlet(s) and the Wi-Fi Gateway to a router. Wi-Fi
connection should be established automatically.
NOTE
The repeater adopts the SSID, password and
authentication type of its paired Wi-Fi Gateway
instead of using the values on its label.
NOTE
Inverters within the site may connect to the repeater
or directly to the Wi-Fi Gateway, depending on their
distance from the gateway and on signal strength.
