Mounting and Connecting the SolarEdge Gateway
The SolarEdge gateway can be installed on a wall or on a DIN rail.
►To mount the SolarEdge gateway on a wall:
1Determine the mounting location. Leave clearance from all sides of the SolarEdge gateway for cover
opening, cable connection and routing.
2Open the clips at the rear of the gateway by pushing the clips outwards.
Figure 4: Clips in Open position
3Position the device on the wall with the open clips, as shown in Figure 4. Mark points through the
holes of the clips and drill holes using a 4mm diameter drill bit.
4Mount the unit using screw anchors and screws (use 3.5mm diameter screws, 20mm minimum
length, not provided by SolarEdge).
►To mount the SolarEdge gateway on a DIN rail:
1Ensure that the clips are closed, as shown below:

2Hook the two lower clips of the SolarEdge gateway onto the lower edge of the DIN rail.
3Press the SolarEdge gateway upwards and snap it into the upper edge of the DIN rail. When on the
rail, the clip "grips" the rail on both the top and bottom lips of the rail.
To remove the DIN clip from the rail, simply push upwards on the DIN clip (thereby compressing the
springs in the bottom), pivot the top of the clip off of the rail, and then move the whole clip down to
also release the bottom of the clip. No screwdrivers or special tools are required.
4The following figure shows the gateway’s rear side when mounted on a DIN rail.
Figure 6: Gateway mounted on a DIN rail
Connecting the SolarEdge Gateway to AC
For connecting to power, use the supplied power supply:
1Insert the power supply DC connector to the SolarEdge gateway (see Figure 3).
2Connect the power supply to the AC mains. The LEDs are lit momentarily to indicate power
connection (see Figure 3).
CAUTION:
If you use a non-SolarEdge power supply, check that it has 12Vdc/1A output ratings, and that it is
certified to UL/CSA/IEC60950-1 2ed standards. Limited Power Source output, NEC class 2. Verify
the power supply polarity as marked on the gateway.

Chapter 3: Connecting the SolarEdge
Gateway to the SolarEdge Installation
Overview
The SolarEdge control and communication gateway connects to the PV system installation using the RS485
communication option. The RS485 option enables creating a chain (bus) of up to 31 slave SolarEdge
devices, connected to one master, which can be another SolarEdge device or the SolarEdge control and
communication gateway.
The following is an example of a master gateway connected to a chain of slave inverters.
Figure 5: Example of RS485 connection
The following sections describe how to connect the RS485 bus and how to configure its components.
Connecting and Configuring the RS485
The RS485 bus uses a three-wire cable connecting the RS485-1/2 terminal blocks on the SolarEdge
gateway to the RS485 input of the inverters/SMI.
►To connect the RS485 communication bus between inverters/SMIs and
SolarEdge gateway:
1Use one of the supplied 3-pin terminal blocks: Loosen the screws and insert the wire ends into the
A, Band G pins. For connections longer then 10m use twisted pair wires for A and B wires.

2Choose either RS485-1 or RS485-2 for connection. Connect the 3-pin terminal block to the designated
port on the gateway.
NOTE:
RS485-1 is configured as SolarEdge device by default, therefore RS485-1 is recommended as
the RS485 bus connection point.
3If the gateway is at the end of the RS485 chain, terminate the gateway by switching a termination
dipswitch to ON. The switches in the SolarEdge gateway are marked SW1 for the RS485-1 port
termination and SW2 for the RS485-2 port termination, as shown below:
Figure 8: RS485 connectors and termination switches
4Open the inverter/SMI cover as described in their manual.
5Remove the seal from one of the openings in communication gland #2 of the inverter and insert the
cable through the opening.
6Pull out the 9-pin RS485/RS232 terminal block connector, as shown below:

7Loosen the screws of pins B, Aand Gon the left of the RS-485 terminal block:
For inverter: RS485-1 pins (left-most)
For SMI: RS485-1 (recommended, as this is the default configuration), or RS485-2
Figure 10: RS485/RS232
8Insert the ends of wires into the G, Aand B pins shown above. You can use any color wire for each of
the A, B and G connections, as long as the same color wire is used for all A pins, the same color for all
B pins and the same color for all G pins.
9Connect all B, Aand Gpins in all inverters/SMI. The following figure illustrates this connection
schema (the illustration applies to both inverters and SMI):
Figure 11: Connecting SolarEdge devices (inverters or SMI) in a chain

10 Tighten the terminal block screws.
11 Push the RS485 terminal block firmly all the way into the communication board.
12 Terminate the inverters/SMIs at the two ends of the chain by switching a termination dipswitch
inside the inverter/SMI to ON (move the switch to the top). The switch is located on the
communication board and is marked SW7.
Figure 12: RS485 termination switch
NOTE:
Only the first and last SolarEdge devices in the chain should be terminated. The other devices in
the chain should have the termination switch OFF.
►To configure the RS485 communication bus with SolarEdge inverters/SMI:
By default, all SolarEdge devices are pre-configured as slaves. Slaves can be further configured using the
RS485-x Conf option in the Communication menu.
One device must be set as the master on the RS485 bus. Any one of the SolarEdge devices may be the
master (control and communication gateway, inverter, or SMI). If you connect the installation to the
SolarEdge monitoring portal, the device used to connect to the server must be the master.
The following describes how to configure the master device.
1Press the Enter button until the following message is displayed:

3Short-press the arrow buttons to scroll to the Communication menu. Press the Enter key to select it.
4Select Server RS485-X Conf (X=1 or 2 depending on the specific physical port connection) to
communicate with different external devices (SolarEdge inverters, revenue meters, non-SolarEdge
loggers or non-SolarEdge inverters).
5To configure the master, select the following in the LCD menus:
Communication RS485-1 Conf Device Type SolarEdge
RS485-1 Conf Protocol Master
RS485-1 Conf Slave Detect
The system starts automatic detection of the SolarEdge slave inverters connected to the master
gateway. The gateway should report the correct number of slaves. If not, verify the connections and
terminations. Verify that only one master is configured on the bus.
6Close the inverter/SMI cover and start power production.
7Verify the connection of the Master to the SolarEdge monitoring portal, as described in Verifying the
Connection, below.
Verifying the Connection
1After connection, a message similar to the following appears in the main status screen (see also
Initial Gateway Status on page 32:
RRCR:Diabled
Sensors:Disabled
S e r v e r : L A N < S _ O K >
T o t a l # o f S l a v e s : --
2Verify that S_OK appears, to indicate that the connection to the SolarEdge monitoring portal is
successful. If S_OK is not displayed, refer to Troubleshooting Communication, below.
Troubleshooting the RS485 Communication
1If No Communication is displayed on the SolarEdge gateway, perform the following:
Verify that the RS485 cable is connected to all inverters. Check the connections between the
first inverter in the chain and the other inverters.
Verify that one of the devices is defined as the master and that slaves were detected, as
described in Step 5 above.
2Check the Server Communication Status screen of all the inverters. The following should appear:
Server:RS485
S t a t u s : O K
If the message Master Not Found, check the connections to the master device and fix if required.
