SolarEdge Inverter Installation Guide – MAN-01-00133-1.0
Chapter 1: Introducing the SolarEdge System
Chapter 1: Introducing the SolarEdge System
System Overview
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 the system
components.
SolarEdge Power Optimizer
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:





During fault conditions
The power optimizers are disconnected from the inverter
The inverter’s ON/OFF switch is turned OFF
The AC/DC Safety Switch is turned OFF
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:


Module Add-on power optimizer – connected to one or more modules
Module embedded power optimizer – are embedded into a module
SolarEdge Inverter with AC/DC 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 AC/DC Safety Switch is a manually operated switch for disconnecting the AC and DC power of a
SolarEdge system.
The AC/DC Safety Switch is located below the inverter and is connected to the inverter with AC and DC
wires.
SolarEdge Monitoring Portal
The SolarEdge monitoring portal enables you to monitor the technical and financial performance of one or
more SolarEdge sites. It provides information about present and past performance of each module
individually and about the system as a whole.

Switch and the AC switch of the distribution panel.
Avant de faire ces étapes, éteignez l'onduleur monophasé en mettant sur OFF l'interrupteur ON/OFF
situé au bas de l'onduleur.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to each
other or plugged with appropriate watertight caps.
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.
CAUTION:
This unit must be operated according to the operating specifications in this document.
Cette unité doit être opérée suivant les instructions trouvées dans ce document.
CAUTION:
Cutting the power optimizer input or output cable connector is prohibited and will void the warranty.
Sectionner les cables d’entrées ou de sortie de l’optimiseur est interdit et annule sa garantie.
CAUTION:
Power optimizers are IP65/NEMA4 rated. Choose a mounting location where optimizers will not be
submerged in water.
Les optimiseurs de puissances sont compatibles à la norme IP65/NEMA4. Choisissez le lieu de
montage tel que l’optimiseur ne puisse pas être submergé par l’eau.
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 manufaturer 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:
 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:
▪ The connector manufacturer should explicitly verify compatibility with the SolarEdge
optimizer connector; and
▪ 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.
14
SolarEdge Inverter Installation Guide – MAN-01-00133-1.0
Chapter 2: Installing the Power Optimizers
Afin d'assurer la compatibilité mécanique entre les optimiseurs de puissance SolarEdge et les modules
auxquels ils sont connectés, il faut :
 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:
▪ Le fabricant du connecteur doit explicitement vérifier la compatibilité avec le connecteur
SolarEdge.
▪ 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’s ON/OFF switch 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.

Stainless steel grounding lock washers
Installation Guidelines

This chapter refers only to the module add-on power optimizers. For module-embedded models,
refer to the installations instructions supplied with the embedded module.



The power optimizer can be placed in any orientation.


The minimum and maximum string length guidelines are stated in the power optimizer datasheets.

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.

Do not leave the power optimizers connectors disconnected. Open connectors should be mated to
each other.

Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in, 10-14 AWG: 35 lb-in.
Position the power optimizer close enough to its module so that their cables can be connected.
To allow proper heat dissipation, maintain a 1" (2.5 cm) clearance distance between the power
optimizer and other surfaces.
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.

Chapter 2: Installing 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 holes locations and drill the holes.
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 5/16'' or 1/4'' stainless steel bolts, nuts and
washers. For 3NA series power optimizers, SolarEdge recommends mounting the power optimizer on
a rail with the smooth side facing out, so that the power optimizer’s 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.

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.

location of each power optimizer, as described in Providing Installation Information on page 35.
CAUTION:
Do not leave the power optimizers connectors disconnected. Open connectors should be
mated to each other.
Ne pas laisser les connecteurs d’optimiseurs de puissance découverts et déconnectés. Les
connecteurs ouverts doivent être accouplés les uns aux autres.
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.

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.

Chapter 2: Installing the Power Optimizers

In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the
inverter, the short circuit current ISC and the open circuit voltage VOC hold different meanings from
those in traditional systems. For more information about the SolarEdge systems’ string voltage and
current, refer to the VOC and ISC in SolarEdge Systems Technical Note, available on the SolarEdge
website at
http://www.solaredge.us/files/pdfs/Voc_and_Isc_in_solaredge_sytems_technical_note.pdf

Isolation measurement using a 600V measurement device is also possible.
►
To verify proper power optimizers connection:
1
Measure the voltage of each string individually before connecting it to the AC/DC Safety Switch (or to
a combiner box). Verify correct polarity by measuring the string polarity with a voltmeter. Use a
voltmeter with at least 0.1V measurement accuracy.
2
For troubleshooting power optimizers operation problems, refer to Power Optimizer Troubleshooting

The SolarEdge Monitoring System
The SolarEdge monitoring portal enables accessing SolarEdge site information, including up-to-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.com/files/pdfs/solaredge-monitoring-portal-user-guide.pdf.
The SolarEdge monitoring portal can display logical and physical layouts of the installed system, as follows:

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.

Physical Layout: Shows a schematic physical layout of the components in the system, such as:
inverters, clusters, 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:


View the latest performance of specific components.



Pinpoint the location of alerted components using the physical layout.
Find underperforming components, such as modules, by comparing their performance to that of
other components of the same type.
See how components are connected to each other.
Pair power optimizers remotely.
To display a logical layout, insert the serial numbers 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 on page 35).
The logical and physical mapping can be used for debugging a problem using the SolarEdge monitoring
portal.
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 inverters, 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 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 Chapter 7: Setting Up
Communication on page 49.

Chapter 7: Setting Up Communication
Chapter 7: Setting Up Communication
Power optimizers send information to the inverter via the DC power lines (the PV output circuit). No
additional wires or configurations are required for this purpose. The information is then 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 and is needed only for using the SolarEdge monitoring portal.
This chapter also describes setting up communication between multiple inverters for a master/slave
configuration.
NOTE:
When connecting the communication cables, make sure that the ON/OFF switch at the bottom of the
inverter is turned OFF, and the AC/DC Safety Switch is turned OFF.
When configuring the communication parameters, make sure that the ON/OFF switch is OFF, and
the AC/DC Safety Switch is turned ON.
Communication Connectors
Two communication glands are used for connection of the various inverter communication options. Each
gland has three openings. The table below describes the functionality of each opening. Unused openings
should remain sealed.

Appendix A: Errors and Troubleshooting
Power Optimizer Troubleshooting
Problem
Possible Cause
Possible Solution
String voltage is 0V
Output of one or more power
optimizers is disconnected
Connect all power optimizer outputs
String voltage not 0V but
lower than number of
optimizers
One or more of the power optimizers
are not connected in the string
Connect all power optimizers
One or more of the modules are not
connected properly to their power
optimizer inputs
Connect the modules to the optimizer
inputs
Wrong polarity connection on one of
the strings
Check polarity of the string output
using a voltmeter and correct if
needed.
One or more extra power optimizer
are connected in the string
Check if an extra power optimizer is
connected in the string. If not –
proceed to next solution.
A module is connected directly to the
string, without a power optimizer.
Verify that only power optimizers are
connected in the string and that no
module outputs are connected
without a power optimizer. If the
problem persists, proceed to the next
step.
A malfunction of one of the power
optimizers

Disconnect the wires that
connect the power optimizers in
the string.

Measure the output voltage of
each power optimizer in order
to locate the power optimizer
that does not output the 1V
safety voltage.

If a malfunctioning power
optimizer is located, check its
connections, polarity, module
and voltage.

If a malfunction cannot be
bypassed or resolved, skip the
malfunctioning power optimizer,
thus connecting a shorter
string.

Do not continue before finding
the problem and replacing the
malfunctioning power optimizer.
String voltage higher than
the number of optimizers
WARNING!
If the measured
voltage is too high, the
installation may not have a
safe low voltage.
PROCEED WITH CARE!
A deviation of ±1% per
string is reasonable.
Si la tension mesuree est
trop haute, la tension basse
de securite pourrait
manquer dans l’installation.
REDOUBLEZ DE
PRECAUTION.
Une deviation de ±1% par
string est raisonnable.
Pairing to the inverter
failed
SafeDC mode was previously
disabled using the SolarEdge Key
Enable the SafeDC using the
SolarEdge Key..
The power optimizers are shaded
If you connected the inverter to the
SolarEdge monitoring portal using
one of the communication options,
you can perform pairing remotely.
Before leaving the site, make sure
that the inverter ON/OFF switch is
ON and S_OK indication appears on
the LCD to indicate connection to the
monitoring portal.
