This manual describes how to install and set up ZigBee™
communication between a SolarEdge device (inverters or Safety and
Monitoring Interface) and the SolarEdge home gateway (also
referred to as SolarEdge gateway). The manual instructions and
graphics refer to the inverter; however apply to SMI as well.
This guide assumes that the SolarEdge power harvesting system is
already installed and commissioned. For additional information
about how to install and commission the SolarEdge power harvesting
system, refer to the relevant installation guide.
The guide includes the following chapters:
Chapter 1: Introducing the Home Gateway, page 8, describes
the SolarEdge home gateway functionality and connection.
Chapter 2: Home Gateway User Interfaces, page 11, describes
the home gateway connectors, configuration button, and LEDs.
Chapter 3: Installing the SolarEdge Home Gateway, page 14,
describes how to mount, connect and verify the connection of
the SolarEdge home gateway.
Appendix A: Troubleshooting, page 18, describes connection
and communication problems, and how to troubleshoot them
Appendix B: Configuring the Home Gateway, page 22,
describes how to use the SolarEdge configuration tool for
checking the home gateway settings and setting a static IP to
the home gateway, instead of automatic DHCP, if necessary.
Appendix C: Technical Specifications, page 26, provides the
electrical and mechanical specifications of the SolarEdge home
gateway device.

Chapter 1: Introducing the Home
Gateway
Overview
The SolarEdge home gateway is used for wireless connectivity
between one or more inverters at a site and a remote internet
gateway point. Wireless connectivity allows simplifying the
installations as no outdoor cabling is required. The SolarEdge home
gateway communicates using ZigBee, a standard for low-rate, high-
reliability, and multi device wireless protocol for telemetry
communications.

Figure 2 shows an inverter as an example; however, this illustration
is applicable to other SolarEdge devices, such as Safety and
Monitoring Interface (SMI).
Figure 2: Connection to the SolarEdge Inverter
The home gateway is provided with one slave unit that is installed
inside the inverter. Up to 15 SolarEdge inverters can be supported
per one ZigBee wireless link. In order to enable more than one
inverter, additional slave kits are required (sold separately).

Connectors
USB: Connection to the power supply. This port can also be
used for connecting to a computer for advanced configuration
or SW upgrade.
Ethernet: Connecting the SolarEdge gateway to the SolarEdge
monitoring portal through an Ethernet switch/router. The
Ethernet switch/router should be connected to the Internet.
DIP Switches
Two DIP switches are located at the side of the gateway. They are
used for internal configuration; therefore, their position should not
be changed.
Configuration Button
The configuration button is used for the following:
Discovery of slave devices and associating them to the home
gateway
Diagnosis of communication problems
►To use the configuration button:
Short press: Pressing the configuration button for 5-10
seconds and releasing it - discover slaves (device
discovery)
Long press: Pressing the configuration button for more
than 10 seconds and releasing it - start diagnostics mode
(refer to Appendix A: Troubleshooting on page 18.
LEDs
The gateway has four LED indicators, as follows:

Chapter 3: Installing the
SolarEdge Home Gateway
Installation Guidelines
The following requirements apply when locating and mounting the
SolarEdge gateway:
The SolarEdge home gateway is suitable for mounting indoors
only. For outdoor installation, use an external plastic outdoor
enclosure (not provided by SolarEdge)
The SolarEdge home gateway must always remain in an
ambient temperature of -20°C (-4°F) to +60°C (140°F).
Protect the SolarEdge home gateway from dust, wet
conditions, corrosive substances, and vapors.
Install the SolarEdge home gateway on a wall or place it on the
desk.

Connecting the SolarEdge Gateway
1Install the supplied ZigBee slave module in the slave device
(inverters or SMI) as described in the ZigBee Slave Kit
Installation Guide. To connect more slaves, purchase an
additional ZigBee slave kit for each slave device (sold
separately).
2Connect the power supply to the USB connector and connect
to an AC source. The power LED is lit to indicate power
connection.
3Connect the Ethernet cable between the gateway connector
and the router or switch used to connect to the Internet.
Device Discovery
Press the configuration button on the home gateway for 5-10
seconds and release. Release the button after all LEDS have turned
on. The gateway starts discovering the slave device(s). The device
discovery may take 2-3 minutes, during which all the LEDs blink. The
signal strength LEDs also light up (refer to LEDs on page 13).

Verifying the Connection
1Verify that the S_OK LED is ON, which indicates the
communication with the SolarEdge portal is established. This
may take up to five minutes. If the LED does not light up, refer
to Appendix A: Troubleshooting on page 18.
2After device discovery, verify that the yellow (Link) LED blinks
and indicates the correct amount of slaves, as described in the
following illustration.
Figure 7: Example of LED Blinks for One or Two Slaves
3Verify signal strength: Check that at least two RSSI LEDs are ON,
which indicates medium signal strength. If only one LED is ON,
the signal strength is Low. Consider relocating the home
gateway closer to the inverter to improve reception. If all RSSI
LEDs are OFF, place a SolarEdge ZigBee repeater (sold
separately) between the home gateway and the inverter. Refer
also to Troubleshooting Ethernet Connection, below.

Troubleshooting Ethernet Connection
If the S_OK LED on the gateway is not ON, use the diagnostics mode
to identify the error:
Press the gateway configuration button for more than 10 seconds
and release it (after all LED turn on and then off while pressing). The
home gateway is now in diagnostics mode.
If all LEDs light up –no error has occurred.
If one of the LEDs is OFF, refer to the following table to
diagnose the problem. If more than one problem is
identified, diagnose the top one first
