Chapter 1: Introducing the SolarEdge Power Harvesting System
Chapter 1: Introducing the SolarEdge Power
Harvesting System
The SolarEdge power harvesting solution maximizes the power output from any type of solar Photovoltaic (PV) installation while reducing the average cost per watt. The following sections describe each of the system’s components.
SolarEdge Power Optimizer
The SolarEdge power optimizers are DC-DC converters connected to PV modules in order to maximize power harvesting by performing independent Maximum Power Point Tracking (MPPT) at the module level.
The power optimizers regulate the string voltage at a constant level, regardless of string length and environmental conditions.
The power optimizers include a safety voltage function that automatically reduces the output of each power optimizer to 1 Vdc in the following cases:
l
During fault conditions
l
The power optimizers are disconnected from the inverter
l
The inverter’s ON/OFF switch is turned OFF
l
The Safety Switch is turned OFF
l
Inverter's AC breaker is turned OFF
Each power optimizer also transmits module performance data over the DC power line to the inverter.
Two types of power optimizers are available:
l
Module Add-on power optimizer – connected to one or more modules
l
Smart Module embedded power optimizer – are embedded into a module
SolarEdge Inverter with Safety Switch
The SolarEdge inverter efficiently converts DC power from the modules into AC power that can be fed into the main AC service of the site and from there to the grid. The inverter also receives the monitoring data from each power optimizer and transmits it to a central server (the SolarEdge monitoring portal; requires Internet connection).
The Safety Switch is a manually operated switch for disconnecting the DC power of a SolarEdge system.
The Safety Switch is located below the inverter and is connected to the inverter with AC and DC wires.

Safety
CAUTION!
If you intend to mount the optimizers directly to the module or module frame, first consult
the module manufacturer for guidance regarding the mounting location and the impact, if
any, on module warranty. Drilling holes in the module frame should be done according to
the module manufacturer instructions.
Pour installation à même le module ou la monture du module, consultez d'abord le
fabricant du module sur la position et son impact sur la garantie du module. Le perçage de
trous dans le cadre du module devra se faire suivant les instructions du fabricant.
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module connectors
with the optimizer connectors may be unsafe and could cause functionality problems such
as ground faults, resulting in inverter shut down. In order to ensure mechanical
compatibility of the SolarEdge optimizers and the modules to which they are connected:
l
l
Use identical connectors from the same manufacturer and of the same type on
both the power optimizers and on the modules; or
Verify that the connectors are compatible in the following way:
o The connector manufacturer should explicitly verify compatibility with the SolarEdge optimizer connector; and
o A third-party test report by one of the listed external labs (TUV, VDE, Bureau Veritas UL, CSA, InterTek) should be obtained, verifying the compatibility of the connectors.
Les connecteurs du module doivent être mécaniquement compatibles avec les
optimiseurs de puissance. Sinon, le système SolarEdge installé peut être dangereux ou
causer des problèmes fonctionnels, tels que les défauts de terre, qui peuvent provoquer
un arrêt de l’onduleur. Afin d'assurer la compatibilité mécanique entre les optimiseurs de
puissance SolarEdge et les modules auxquels ils sont connectés, il faut :
l
l
Utiliser des connecteurs identiques du même fabricant et du même type aussi bien
pour les optimiseurs de puissance que pour les modules.
Vérifiez que les connecteurs sont compatibles de la manière suivante:
o
Le fabricant du connecteur doit explicitement vérifier la compatibilité avec le
connecteur SolarEdge.
o
Un rapport de test de tierce partie doit être effectué par l’un des laboratoires externes
indiqués ci-dessous:(TUV, VDE, Bureau Veritas UL, CSA,Intertek), qui vérifiera la
compatibilité des connecteurs.
IMPORTANT SAFETY FEATURE
Modules with SolarEdge power optimizers are safe. They carry only a low safety voltage
before the inverter is turned ON. As long as the power optimizers are not connected to the
inverter or the inverter is turned OFF, each power optimizer will output a safe voltage of
1V.

Package Contents
l Power optimizers
l Stainless steel grounding lock washers
Installation Guidelines
l This chapter refers only to the module add-on power optimizers. For moduleembedded models, refer to the installations instructions supplied with the embedded module.
l The power optimizer can be placed in any orientation.
l Position the power optimizer close enough to its module so that their cables can be connected.
l To allow for heat dissipation, maintain a 2.5 cm/ 1" clearance distance between the power optimizer and other surfaces.
l The minimum and maximum string length guidelines are stated in the power optimizer datasheets. l Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is available on the SolarEdge website at http://www.solaredge.us/groups/support/downloads, under Software Tools.
l Completely shaded modules may cause their power optimizers to temporarily shut down. This will not affect the performance of the other power optimizers in the string, as long as the minimum number of unshaded power optimizers connected in a string of modules is met. If under typical conditions fewer than the minimum optimizers are connected to unshaded modules, add more optimizers to the string.
l Do not leave the power optimizers connectors disconnected. Open connectors should be mated to each other.
l Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in, 10-14 AWG: 35 lb-in.

Step 1: Mounting and Grounding the Power Optimizers
Step 1: Mounting and Grounding the Power
Optimizers
1. Determine the power optimizer mounting location and use the power optimizer mounting brackets to attach the power optimizer to the support structure (See Figure 4). For optimizers supplied with module frame-specific brackets, attach the power optimizer to the module frame following the instructions included with the optimizers.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling
vibrations can damage the power optimizer and will void the warranty.
Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation. Les vibrations
qui en résulteraient peuvent endommager la optimiseur de puissance.
3. Attach each power optimizer to the rack using the M6 (1/4'') stainless steel bolts, nuts and washers. Apply torque of 9.5 N*m / 7 lb*ft. For 3NA series power optimizes, SolarEdge recommends mounting the power optimizer on a rail with the smooth side facing out, so that the power optimizer body will prevent its rotation.
4. Use the following methods to ground the power optimizer1:
WARNING!
The metallic enclosure of the power optimizer must be grounded in accordance with the
requirements of the local and national codes.
L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en accord avec
les régulations locales et nationales.
l For mounting on a grounded metal rail : Use the provided 5/16'' stainless steel grounding star washer between the railing and the flat side of the mounting bracket. The grounding washer should break through the anodize coating of the railing to ensure low resistive connection. Apply torque of 9.5 N*m / 7 lb*ft.
1For a list of racking models and their appropriate grounding method, refer to
http://www.solaredge.us/files/pdfs/grounding_se_power_optimizers.pdf.

Les connecteurs d’entrée et sortie ne sont pas étanches jusqu'à ce qu’ils soient accouplés.
Les connecteurs doivent être accouplés ou fermés avec des terminaux étanches.
Step 4: Verifying Proper Power Optimizer
Connection
After a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V. Therefore, the total string voltage should be equal to 1V times the number of power optimizers connected in series in the string. For example, if 10 power optimizers are connected in a string, then 10V should be produced.
l Make sure the modules are exposed to sunlight during this process; otherwise, the power optimizers may not be powered. If you use a tracker, the power optimizer will turn ON only if the tracker is tracking the sun and the module provides at least 2W.

SolarEdge-Installation Guide MAN-01-00002-4.0
Chapter 2: Installing the Power Optimizers
l In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V SC
OC
hold different meanings from those in traditional systems. For more information about the SolarEdge system’s string voltage and current, refer to the V and I in SolarEdge Systems Technical Note, available on the SolarEdge OC
SC
website at: http://www.solaredge.us/files/pdfs/isc_and_voc_in_solaredge_sytems_
technical_note.pdf
To verify proper power optimizers connection:
Measure the voltage of each string individually before connecting it to the other strings or to the inverter. Verify correct polarity by measuring the string polarity with a voltmeter. Use a voltmeter with at least 0.1V measurement accuracy.

Setting the Inverter for 208V Delta Grid Support
SolarEdge inverters that support the 208V Delta grid are equipped with two fuse holders and a fuse. The position of the fuse configures the AC grid connection: WYE (4- wire) or Delta (3wire) grid connection. By default, the fuse is located in the WYE fuse holder of the inverter, and in the Delta fuse holder there is a plastic dummy fuse.
To set the inverter for Delta grid connection, you must move the fuse from the WYE fuse holder, marked as Y GRID, to the Delta fuse holder, marked as ∆ GRID (see Figure 25).
CAUTION!
The only supported Delta grid is the 208V L-L grid. Connecting the inverter to other Delta
grids may damage the inverter and will void the warranty.
To set the inverter for 208V Delta grid connection:
NOTE
Perform this procedure before connecting the inverter Safety Switch to the AC grid.
1. Remove the inverter cover: Open the inverter cover’s six Allen screws and carefully pull the cover horizontally before lowering it.
2. Identify the fuse locations and the markings as described in Figure 25
Figure 25: Fuse locations and markings
3. Remove the dummy fuse from the Delta grid fuse holder and set it aside. 4. Move the fuse from the WYE grid fuse holder to the Delta grid fuse holder. 5. Place the dummy fuse in the WYE grid fuse holder. SolarEdge-Installation Guide MAN-01-00002-4.0

Chapter 4: Connecting the AC and the Strings to the Safety Switch
Connecting the Strings to the Safety Switch
Strings may be connected in parallel to the two DC input pairs of the switch. If more than two strings are required, they can be connected in parallel using an external combiner box before connecting to the switch. When connecting multiple strings, it is recommended to run separate circuits to the Safety Switch or to position the combiner box near the switch. This simplifies commissioning by allowing testing and servicing near the inverter.
To connect the strings to the safety switch:
1. Strip 5⁄16'' (8 mm) of the DC wire insulation.
2. Insert the DC conduit into the DC-side knockout that was opened.
3. Equipment grounding: Connect the DC equipment ground conductor to the equipment grounding terminal block in the Safety Switch.
NOTE
Functional Electrical Earthing of DC-side negative or positive is prohibited because the
inverter has no transformer. Earthing of module frames and mounting equipment
(equipotential bonding) is required per NEC.
4. Connect the DC wires:
CAUTION!
Ensure that the Plus (+) wire is connected to the + terminal and that the Minus (-) wire is
connected to the Minus (-) terminal connector.
Veillez à ce que le câble Plus (+) soit connecté au terminal + et que le câble - soit connecté
au connecteur terminal.
NOTE
If more than two strings are connected each should be properly fused on both DC+ and
DC- according to NEC690.35(B).
NOTE
SolarEdge's fixed input voltage architecture enables the parallel strings to be of different
lengths. Therefore, they do not need to have the same number of power optimizers, as
long as the length of each string is within the permitted range.
l For single phase 3-7.6kW inverters - 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, as described for the AC connection of single phase 3-7.6kW inverters (connect the AC grid to the Safety Switch – single phase 3-7.6kW inverters: on page 38).

The SolarEdge Monitoring System
The SolarEdge monitoring portal enables accessing SolarEdge site information, including upto-date information viewed in a physical or logical view.The monitoring portal is described in detail in the SolarEdge Monitoring Portal User Guide, available on the SolarEdge website at http://www.solaredge.us/files/pdfs/solaredge-monitoring-portal-user-guide.pdf. The SolarEdge monitoring portal can display logical and physical layouts of the installed system, as follows:
l Logical Layout: Shows a schematic logical layout of the components in the system, such as: inverters, strings and modules, as well as their electrical connectivity. This view enables you to see which modules are connected in each string, which strings are connected to each inverter, and so on.
l Physical Layout: Shows a schematic physical layout of the components in the system, such as: inverters, strings and modules, as well as their electrical connectivity. This view enables a bird’s eye view of the actual location of a system component.
Using the portal, you can:
l View the latest performance of specific components.
l Find under-performing components, such as modules, by comparing their performance to that of other components of the same type.
l Pinpoint the location of alerted components using the physical layout.
l See how components are connected to each other.
l Pair power optimizers remotely.
To display a logical layout, insert the inverter serial number in the new site created in the application. When the communication between the inverter and the monitoring server is established, the logical layout will be displayed.
To display a physical layout, you need to map the locations of the installed power optimizers. To generate a physical mapping, use either the iPhone Site Mapper application or a mapping template, which should be filled out using the detachable stickers (see Providing Installation
Information, below).
The logical and physical mapping can be used for debugging a problem using the SolarEdge monitoring portal.

SolarEdge-Installation Guide MAN-01-00002-4.0
Chapter 5: Commissioning the Installation
If you do not report the physical and logical mapping of the installed power optimizers to SolarEdge, the SolarEdge monitoring portal will show the logical layout indicating which power optimizers are connected to which inverter, but will not show strings or the physical location of power optimizers.
The inverter may be connected to the SolarEdge monitoring portal via LAN or via an external modem connected to the inverter's RS232 connector. Alternatively, you can connect the inverter to another inverter that is already connected to the server, in a master-slave configuration. Refer to Setting Up Communication on page 71 .
Providing Installation Information
Paper Template
Fill out the Physical Layout Template (downloadable from the SolarEdge site) using the detachable 2D barcode stickers on each power optimizer. Once the form is completed, scan it and upload the scanned file to the SolarEdge monitoring portal during site registration. For an example paper template, refer to http://www.solaredge.us/files/pdfs/physical-layouttemplate.pdf.
Site Mapper
Use the SolarEdge Site Mapper smartphone application to scan the power optimizer and inverter 2D barcodes. The application creates an XML file that can be uploaded to the SolarEdge monitoring portal during site registration. The SolarEdge Site Mapper can be downloaded from the application stores.
For detailed information, refer to the SolarEdge Site Mapper Software Guide or to the Site
Mapper demo movie, available on the SolarEdge website at http://www.solaredge.us/groups/installer-tools/site-mapper.
Creating a Site in the SolarEdge Monitoring Portal
Create the site in the monitoring portal using the registration form available at http://www.solaredge.us/groups/site-registration . Fill out all required information in the form, which includes information about your installation, as well as details about its logical and physical mapping.

Power optimizers send information to the inverter via the DC power lines (the PV output circuit). The information is sent from the inverter to the SolarEdge monitoring portal through the Internet. In order to send the data from the inverter, a communication connection must be set up, as described in this chapter. Communication setup is not required for power harvesting, however is needed for using the SolarEdge monitoring portal.
This chapter describes setting up communication between multiple inverterss for a master/slave configuration.
CAUTION!
When connecting the communication cables, make sure that the ON/OFF switch at
the bottom of the inverter is turned OFF, and the AC is turned OFF.
When configuring the communication parameters, make sure that the ON/OFF
switch is OFF, and the AC is turned ON.
Communication Types
l Ethernet: used for a LAN connection
l RS485: used for the connection of multiple SolarEdge devices on the same bus in a master-slave configuration. RS485 type can also be used as an interface to external non-SolarEdge devices, such as revenue meters and data loggers.
l ZigBee: Optional wireless communication (purchased separately).
l Cellular: Optional cellular wireless connection (purchased separately).
Only communication products offered by SolarEdge are supported.
Always connect the communication options when the inverter is OFF.

Creating an RS485 Bus Connection
NOTE
If a revenue grade meter is connected to your inverter, it uses the RS485 port and
therefore an RS485 communication bus cannot be created.
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
To connect the RS485 communication bus:
1. Remove the inverter cover as described in Removing the Inverter Cover on page 73
2. Remove the seal from one of the openings in communication gland #2 and insert the wire through the opening.
3. Pull out the 9-pin RS485/RS232 terminal block connector, as shown below:
Figure 38: The RS485 terminal block
4. Loosen the screws of pins A(+), B(-), and G on the left of the RS485 terminal block.
Figure 39: RS485/RS232 terminal block
5. Insert the wire ends into the G, A and B pins shown above. Use Four- or six-wire twisted pair cable for this connection. 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 78
SolarEdge-Installation Guide MAN-01-00002-4.0
Chapter 7: Setting Up Communication
pins and the same color for all G pins.
6. For creating an RS485 bus - connect all B, A and G pins in all inverters. The following figure shows this connection schema:
Figure 40: Connecting the inverters in a chain
NOTE
Do not cross-connect B, A and G wires. Do not insert wires into RS485- 2 pins.
7. Tighten the terminal block screws. 8. Check that the wires are fully inserted and cannot be pulled out easily. 9. Push the RS485 terminal block firmly all the way into the connector on the right side of the communication board. 10. Terminate the first and last SolarEdge device (inverter/SMI/Control and communication gateway, etc.) in the chain by switching a termination DIP-switch inside the inverter to ON (move the switch up). The switch is located on the communication board and is marked SW7. SolarEdge-Installation Guide MAN-01-00002-4.0

Appendix D: External Fan Maintenance and
Replacement
The three phase and single phase 10-11.4kW inverters have two fans: one is internal and requires a SolarEdge technician to replace and the other is accessible from the outside of the inverter.
The fans are referred to as “Fan 1” and “Fan 2”:
l In three phase inverters - Fan 1 is internal, Fan 2 is external
l In single phase 10-11.4kW inverters - Fan 1 is external, Fan 2 is internal
l In single phase 7.6kW inverter has one internal fan, referred to as Fan 1.
A fan replacement kit is available from SolarEdge.
Figure 52: Inverter external fan
Fan Maintenance
1. At least once a year, open the fan screen and clean the accumulated dust using a brush.
2. Check the Fan Status screen on the LCD (refer to Fan Status on page 69).
3. If one of the following occurs, replace the fan as described below:
l When the fan stops operating
l Fan status is Not Working; Before replacing the fan, turn the inverter AC OFF and ON and check if the status is cleared
l The following Error is displayed:
o In Three Phase inverters: Fan 2 Failure
o In single Phase 10-11.4 kW inverters: Fan 1 Failure
External Fan Replacement
1. Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC voltage is safe (<50V), or wait five minutes before continuing to the next step.

Appendix F: Inverter Arc Detection and Interruption
Appendix F: Inverter Arc Detection and
Interruption
The arc detection option may be disabled by default. It must be enabled when UL1699B compliance is required. When enabled, the inverter performs an automatic self-test for arc fault each time the inverter wakes-up or is switched ON.
To enable/disable arc detection:
1. Use the LCD light button to enter Setup mode (refer to Configuring the Inverter Using the
LCD Light Button on page 55). 2. Short-press the LCD light button to reach the Maintenance menu. 3. Select AFCI è Enable or Disable.
To manually test the arc detection functionality:
1. Make sure the inverter ON/OFF switch is turned ON. 2. Use the LCD light button to select Maintenance è Manual AFCI Test. l If the test is successful, the following message is displayed: Manual
Test PASS
The inverter production is then interrupted (as if a real arc detection has occurred), and the following error message is displayed (numbered either 150 or 151): Error
Arc
151
Fault
Detected
Perform manual restart to resume system operation: Turn the inverter ON/OFF switch to OFF and then to ON. The inverter performs an arc detection self-test and starts normal operation. l If the test fails, contact SolarEdge support.
To troubleshoot arc-fault failures:
The inverter continuously performs arc detection while producing power. If an electric arc occurred in the PV system, the inverter detects it and stops producing power. The following error message is displayed (numbered either 150 or 151):
Error
Arc
151
Fault
Detected
