Chapter 1: Introducing the SolarEdge
Firefighter Gateway
Overview
The firefighter gateway provides centralized safety management of SolarEdge systems:
If the firefighter gateway is properly installed and fully functional, firefighters can halt
production of a SolarEdge photovoltaic (PV) power harvesting system and have visual
acknowledgment that the installation outputs a safe DC voltage. The power production
can be stopped either manually through an emergency stop button or automatically
through a Fire Alarm Control Panel system. This stops the AC production and reduces
string DC voltage to a safe voltage using the unique SafeDC™ feature.
Although DC voltage can be reduced directly from the inverter or by shutting off the AC
voltage, using the firefighter gateway provides a clear indication of DC voltage
shutdown. The firefighter gateway enables shutting off the installation from a distance
of up to 1,000m, while getting visual feedback that the PV installation is safe.

The LCD screen displays status information of the system and various menus for
configuration options. The LCD panel and buttons are used during the following
processes:
Operational mode: The LCD panel allows checking for proper system operation.
Refer to Status Screens - Operational Mode on page 29 for a description of this
option.
Setup mode: Upon installation, an installer may perform basic configurationas
described in Configuration Menu Options on page 33.
Error messages: In the event of a problem, an error message may be displayed on
the LCD panel.
For more information, refer to Errors and Troubleshooting on page 56.
Use the four user buttons to control the LCD panel menus:
Esc: Moves the cursor (>) to the beginning of the currently displayed parameter;
goes to the previous menu, and cancels a value change with a long press (until
Aborted is displayed).
Up (1) and Down (2): Moves the cursor from one menu option to another, moves
among the characters of a displayed parameter, and toggles between possible
characters when setting a value.

The gateway must always remain in an ambient temperature of-20°C (-4°F) to +60°C
(140°F).
The gateway power supply requires a socket outlet with a grid voltage of 100 V -
240 V (50/60Hz).

NOTE
If using a cable longer than 10 m/33 ft in areas where there is a
risk of induced voltage surges by lightning, it is recommend to
use external surge protection devices. For details refer to:
http://www.solaredge.com/files/pdfs/lightning_surge_protection.pdf. If
grounded metal conduit are used for routing the communication wires, there
is no need for a lightning protection device.

Mounting and Connecting the Firefighter Gateway
The gateway can be installed on a wall or on a DIN rail.
To mount the Commercial Gateway on a wall:
1. Determine the mounting location. Leave clearance from all sides of the gateway for
cover opening, cable connection and routing.
2. Position the device on the wall, mark points through the mounting tabs and drill
holes using a 4mm diameter drill bit.
3. Mount the unit using screw anchors and screws (use 3.5mm diameter screws, 20mm
minimum length, not provided by SolarEdge).
Figure 4: Firefighter Gateway mounting tabs
To mount the Commercial Gateway on a DIN rail:
1. Press the gateway upwards and snap it into the upper and lower edges of the DIN
rail.

Connecting the Firefighter Gateway to AC
For connecting to power, use the supplied power supply:
1. Connect the power supply cable connector to the connector labeled DC on the
Firefighter Gateway (see Figure 3 ).
2. Connect 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 Firefighter Gateway
to the Installation
Overview
The Firefighter 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 Firefighter Gateway.

NOTE
Only SolarEdge devices (inverters, Commercial Gateways (CCGs) and
Dataloggers) are allowed on the RS485 communication bus.
The following is an example of a slave gateway connected to a chain of slave inverters
(one inverter is the master).

Figure 6: Example of RS485 connection
The following sections describe how to connect the RS485 bus and how to configure its
components.
Creating an RS485 Bus Connection
The RS485 bus uses a three-wire cable connecting the RS485-1 terminal blocks on the
Firefighter Gateway to the RS485 input of the inverters.
To connect the RS485 communication bus between inverters and the Firefighter
Gateway:
1. Use one of the supplied 3-pin terminal blocks: Loosen the screws and insert the wire
ends into the A, B and G pins. For connections longer then 10m use twisted pair
wires for A and B wires.
Chapter 3: Connecting the Firefighter Gateway to the Installation 18
Firefighter Gateway Installation Guide MAN-01-00113-1.4

Figure 7: 3-pin terminal block
2. Connect the 3-pin terminal block to the designated RS485-1 port on the Firefighter
Gateway.

NOTE
RS485-1 is configured as SolarEdge device by default, therefore RS485-
1 is used as the RS485 bus connection point.
3. If the Firefighter Gateway is at the end of the RS485 chain, terminate the Firefighter
Gateway by switching a termination DIP switch to ON. The switches in the SolarEdge
Firefighter Gateway are marked SW1 for the RS485-1 port termination (and SW2), as
shown below:
Figure 8: RS485 connectors and termination switches
4. Open the inverter cover as described in their manual.
5. Remove the seal from one of the openings in communication gland #2 of the
inverter and insert the cable through the opening.
6. Pull out the 9-pin RS485 terminal block connector, as shown below:

7. Loosen the screws of pins B, A and G on the left of the RS-485 terminal block.
Figure 10: RS485 terminal block
8. Insert the wire ends into the G, A and 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.
9. Connect all B, A and G pins in all inverters. The following figure illustrates this
connection schema (the illustration applies to inverters):
