For full installation and safety details, you must refer to the SolarEdge Installation Guide. Make sure you read, fully understand and follow the
detailed instructions in the SolarEdge Installation Guide prior to each installation. Failure to do so could result in injury or loss of life and
damage or destruction of the equipment.
The images contained in this document are for illustrative purposes only and may vary depending on product models.
For mounting on rails with sliding nut fasteners, or an un-grounded Optional grounding
terminal
structure (such as a wooden structure): Connect an equipment-grounding
conductor to the grounding terminal according to the instructions supplied
with the grounding terminals (grounding terminal kits are available from
SolarEdge). The grounding terminal accepts a wire size of 6-14 AWG, and must be
sized for equipment grounding per NEC 250.122 requirements. Tighten the screws
connecting the power optimizer to the frame and the grounding terminal screw.
Apply torque of 9.5 N*m / 7 lb*ft.

Installing the Inverter
1 Make sure that the inverter ON/OFF switch at the bottom of the inverter is switched OFF before and during the installation, and that the
AC circuit breaker is OFF.
2 Use a 5mm Allen key to open the AC/DC Safety Switch cover screws and remove the cover.
3 Open the required knockout pair (bottom, back or sides of the enclosure, sized ¾'' or 1'') according to the conduits used in the installation.
4 Make sure to leave clearance areas in order to cool the inverter: 8" above, at least 4" below (leaving sufficient clearance for conduits
entering from the bottom) and 4" on either side.
The inverter is supplied with one of the following two types of mounting brackets.The mounting steps in the next sections refer to these
types.
Type 1 Type 2
For type 1:
Install the mounting bracket on the wall with the U-shaped Mounting bracket orientation
indentations facing up, and the “UP” marking is correctly oriented.

5 Optionally, secure the Safety Switch bracket to the wall:
Mark the location of the bracket screw for the AC/DC Safety Switch and drill the hole.
Fasten the bracket using a standard bolt.

WARNING!
Connect the equipment grounding before connecting the AC wires to the AC terminal block.
Veillez à relier le conducteur de PE (la terre) avant de connecter les fils CA au bornier CA.
1 Insert the AC conduit into the AC-side knockout that was opened.
2 Connect the wires, and check that they are fully inserted and cannot be pulled out easily:

Three phase inverter
For AC/DC Safety Switch: - Connect the Ground and Neutral wires to the - L1 L2 L3
terminal blocks in the AC side of the switch. Connect the line wires to the
appropriate connectors according to the label located in the switch.
For DC Safety Switch: Use a standard flat-blade screwdriver to connect Press here with a
the wires to the spring-clamp terminals screwdriver
NOTE:
Three phase inverters require neutral connection at all times (only WYE type grids with neutral connection are supported).
Single phase 3-6kW inverter - Connect the DC wires from the PV installation to the DC+ and DC- terminal blocks, according to the labels on
the terminals. Use a standard straight-bladed screwdriver to connect the wires to the spring-clamp terminals. Refer to the figures above.
Single phase 7.6-11.4kW inverter - Connect the DC wires from the PV installation to the DC+ and DC- terminal blocks, according to the
labels on the terminals. Use standard flat-blade screwdriver to connect the wires to the spring-clamp terminals as shown in the figures
above.
CAUTION:
Ensure that the Plus (+) wire is connected to the Plus (+) terminal and that the Minus (-) wire is connected to the Minus (-) terminal.
Veillez à ce que le câble Plus (+) soit connecté au terminal Plus (+) et que le câble Minus (-) soit connecté au terminal Minus (-).
4 If more than two strings are required, they can be connected in parallel in an external combiner box before connecting to the switch.
NOTE:
If more than two strings are connected each should be properly fused on both DC+ and DC- according to NEC690.35(B).
5 If the Safety Switch has a pre-assembled RGM, flip the RGM plate upwards to its original position.
6 Close the switch cover.

7 If required, perform the following additional steps before closing the inverter cover:
Country settings or inverter configuration using the internal LCD user buttons, located just above the LCD
and are numbered esc, 1, 2, 3/Enter from left to right. Enter the menus by pressing ENTER for five
seconds and then inputting the password 12312312. To verify that the country code is set to USA, select
Country from the main menu, press Enter and select USA+. In the next menu that appears, select the
desired AC grid configuration.
Communication options connection – refer to Setting up Communication on page 6.
8 Close the inverter cover by tightening the screws with a torque of 9.0 N*m/ 6.6 lb*ft. For proper sealing, first tighten the corner screws
and then the two central screws.
9 Make sure the AC/DC Safety Switch is ON. If an additional external DC switch is installed between the power optimizers and the inverter(s)
then turn it ON.
A message similar to the following appears on the inverter LCD panel:
V a c [ v ] V d c [ v ] P a c [ w ]
2 4 0 . 7 1 4 . 1 0 . 0
P _ O K : 0 0 0 / 0 0 0 < S _ O K >

WARNING!
Before proceeding to the next step, make sure that the cover is closed! High DC Voltage will be present in the inverter following the next step!
Avant d’entamer la prochaine étape, assurez vous que le couvercle est fermé ! Une tension DC très haute sera présente durant l’étape
suivante !

Pairing Power Optimizers to the Inverter
1 Verify that the ON/OFF switch at the bottom of the inverter is OFF.
2 Press and hold down the inverter LCD button for about 10 seconds. The following message is displayed:
K e e p h o l d i n g b u t t o n
f o r p a i r i n g , r e l e a s e
t o e n t e r m e n u . . .
R e m a i n i n g : 3 s e c
3 Turn the inverter ON within 5 seconds. If you wait longer than 5 seconds, the inverter exits the pairing mode. The following message is
displayed indicating that the inverter is performing the pairing.
P a i r i n g
R e m a i n i n g [ s e c ] : 1 8 0
4 Wait for the completion of the pairing (remaining seconds is 0). If pairing fails, an error is displayed. In this case, repeat the pairing steps.
5 When pairing succeeds, the following message is displayed:
P a i r i n g
P a i r i n g C o m p l e t e d
6 At the end of the pairing process, the system will start producing power. Verify on the LCD screen that the number next to P_OK equals
the number of installed power optimizers. It may take up to 20 minutes until all the power optimizers are indicated.
WARNING!
After you turn ON the inverter ON/OFF switch, the DC cables carry a high voltage and the power optimizers no longer output a safe
1V output.
Après avoir mis l'interrupteur ON/OFF de l'onduleur monophasé sur ON, les câbles DC portent une haute tension et les optimiseurs
de puissance ne génèrent plus la tension de sécurité de 1V.
WARNING!
After you turn OFF the inverter ON/OFF switch, wait until the LCD indicates that the DC voltage is safe (<50V), or wait five minutes
before opening the cover or disconnecting the strings.
Apres avoir tourné l’interrupteur ON/OFF sur OFF, attendre jusqu'à ce que l’écran LCD indique que la tension DC est sécurisée
(<50V) ou attendre cinq minutes avant d’ouvrir le couvercle ou de déconnecter les strings.

3 Use a pre-crimped cable to connect via gland no.1 to the RJ45 plug on the inverter's communication board, or, if using a cable drum,
connect as follows:
Insert the cable through gland no.1.
Insert the eight wires into an RJ45 connector, as described in the figure above.
Use a crimping tool to crimp the connector.
Connect the Ethernet connector to the RJ45 plug on the inverter's communication board.
4 For the switch/router side, use a pre-crimped cable or use a crimper to prepare an RJ45 communication connector: Insert the eight wires
into the RJ45 connector, maintaining the same color coding and pinout on both sides of the Ethernet cable.
5 Connect the cable’s RJ45 connector to the RJ45 port of the Ethernet switch or router.
6 Inverters are configured by default to LAN. If reconfiguration is required:
Turn ON the AC to the inverter by turning ON the circuit breaker on the main distribution panel.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is removed.
RISQUE D’ÉLECTROCUTION. Ne touchez pas les fils non isolés lorsque le couvercle de l'onduleur est retiré.
Use the user buttons to configure the connection.
Refer to the SolarEdge Installation Guide for detailed installation and safety instructions.
