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 acknowledgement 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 stig DC voltage to a safe voltage usig the uiue “afeDC™ featue.
The firefighter gateway can connect to SolarEdge inverters and to Safety and Monitoring Interfaces (SMIs).
Although DC voltage can be reduced directly from the inverter/SMI 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.

Chapter 3: Connecting Emergency Stop
Button or Fire Alarm Control
Overview
An external emergency stop button (not supplied by SolarEdge) should be connected to the firefighter
gateway, in order to shut down the PV system in case of emergency. Pressing the emergency stop button
starts the shutdown sequence of the PV system. Preferably, use a button with a locking feature that stays
mechanically locked in the off position until you turn it clockwise a quarter turn to unlock and release it.
The firefighter gateway can also be connected to a fire alarm control unit that has a relay output. The relay
output of the fire alarm control has the same functionality as the button. You can connect both a stop
button and a relay together to the same firefighter gateway, or two stop buttons or two relays.
Figure 7: Example: Emergency Stop Button and Fire Alarm System Connection
The emergency stop button(s) or relay(s) connect to the L1 or L2 ports on the Control connector of the
gateway, between 5V and L1 / L2/both. In the following sections, the instructions refer to L1, however
applies to L2 as well.
Figure 8: Emergency Stop Button Connection

Chapter 3: Connecting Emergency Stop Button or Fire Alarm Control
Firefighter Gateway Installation Guide MAN-01-00113-1.2

There are two types of contact states in Emergency Stop buttons/relays:
Normally open (NO) –the contacts are open until closed by operation of the switch. This type of
switch should be connected in the following manner:
This installation is safe when L1/L2 has 5V input, and active with L1/L2 is not connected. This is
considered Normal polarity in the configuration screen.
Normally closed (NC) –the contacts are closed until opened by operation of the switch. This type of
switch should be connected in the following manner:
This installation is safe when L1/L2 is not connected and active when L1/L2 is 5V. This is considered
Reverse polarity in the configuration screen.
If you connect more than one firefighter gateways to the same emergency stop button, they should
connect to the same grounding, as in the following example:
In some fire alarm control systems, the switch is grounded internally. This type of switch should be
connected in the following manner, sharing ground between the control system and the firefighter
gateway.
In these cases, a Normally Open relay will connect L1/L2 to ground for safety, and when active, L1/L2
is 5V. This will be configured as a reverse polarity switch.

Chapter 4: Connecting the Firefighter
Gateway to the SolarEdge Installation
Overview
The SolarEdge 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 SolarEdge firefighter gateway.
The following is an example of a slave gateway connected to a chain of slave inverters (one inverter is the
master).
Figure 10: 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.
