Chapter 1
Introducing the SolarEdge Power
Harvesting System
What is the SolarEdge Power
Harvesting Solution?
The SolarEdge power harvesting solution maximizes the power output from any
type of solar PV installation while reducing the average cost per watt. The
sections below describe each of the system’s components.
SolarEdge Power Optimizer
SolarEdge power optimizers can be connected to existing PV modules in order to
maximize power harvesting by locally performing Maximum Power Point
Tracking (MPPT) at the PV module level.
The power optimizers keep the string voltage fixed, regardless of the length of the
string and of the environmental conditions. Each SolarEdge power optimizer
directly transmits performance data from every PV module over the power line.
Two types of power optimizers are provided by SolarEdge, as follows:
Module add-on solutions, connected during installation to one or more PV
module. P/N: OP250-LV, OP300-MV, OP400-MV and OP400-EV.
Module embedded solution (CSI), is supplied embedded into a PV module.
You may refer to the SolarEdge power optimizer datasheets in order to determine
which power optimizer is most suitable for you requirements.

SolarEdge Inverters
The SolarEdge Single Phase and Three Phase Inverters efficiently convert DC
power received from the PV modules into AC power that can be fed into the main
circuit board of the site and from there to the grid. The inverters also receive the
monitoring data from each power optimizer and transmit it to a central server
(called the Monitoring Server) through an Ethernet network to an external modem
connection.

CAUTION:
If installing directly on the module or module frame, first consult the module
manufacturer for guidance regarding location and the impact on the module warranty.
CAUTION:
SolarEdge power optimizers and inverters use connectors from the following
manufacturers:
Multi Contact MC4
Amphenol H4
Tyco keyed connector
Huber Suhner Raddox
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 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.
NOTE:
The power optimizer may be placed in any orientation, meaning there is no up
direction.
NOTE:
The power optimizer should be mounted in a location that is either ventilated or that
has a free space of air around it for heat dissipation.
NOTE:
Mounting brackets are suited to either a flat surface or a pole and can be attached to
any surface texture.

Chapter 2
Installing the Power Optimizers
Applicable Notes and Warnings
The following notes and warnings apply when installing the SolarEdge power
optimizers:
photovoltaikforum.com
Page 14
Installing the Power Optimizers
14
IMPORTANT SAFETY FEATURE:
PV modules with SolarEdge power optimizers are safe. They only carry a low safety
voltage before the inverter is turned on.
IMPORTANT SAFETY FEATURE:
As long as the power optimizers are unconnected to the inverter or the inverter is
OFF, the power optimizers will output a safe 1V voltage during installation.
IMPORTANT NOTE:
SolarEdge power optimizers are energized by the PV modules to which they are
connected. String length must not be less than eight power optimizers when using a
single phase inverter and sixteen power optimizers when using a three phase inverte,
or the entire string may shut down. (Please refer to the power optimizer datasheets for
the exact minimum and maximum number of power optimizers permitted in a string.)
NOTE:
Completely shaded PV modules may cause the affected 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 string length requirement is met when taking into account
the lighted modules only. If under typical conditions modules connected to fewer than
eight optimizers in a single phase system or to fewer than sixteen optimizers in a three
phase system will remain unshaded, add more PV modules.
CAUTION:
Do not drill through the power optimizer or through the mounting holes. The vibrations
created by the drill can damage the power optimizer and will void the warranty.
SolarEdge Installation Guide – MAN-01-00057-2.0
Step 1, Mounting the Power
Optimizers
Determine the mounting location of each power optimizer. The power
optimizer should be mounted in a place where it can be mounted securely
using both mounting holes. It must also be located near enough so that the
power optimizer can connect to a single PV module. Mark all mounting hole
locations.
Each power optimizer must be attached to the rack using both mounting
holes.
Drill the holes.
Mount one power optimizer at each location using M6 (1/4”) screws and
washers.
Verify that the power optimizer is securely attached.

WARNING!
Before performing this step, turn OFF the inverter by turning off the ON/OFF switch at
the bottom of the inverter and the AC switch of the main circuit board. All inverters in
an installation site should be switched OFF in this manner. This step is required to
verify that the power optimizers will output a safe 1V voltage during installation.

WARNING!
Verify that you have identified the inputs and outputs correctly. Do not connect PV
modules to power optimizer outputs.
NOTE:
The power optimizer has reverse polarity protection. Even so, you must still verify the
correct polarity by checking the PV module’s polarity with a voltmeter. Some module
manufacturers may use connector polarity that is different from that used by
SolarEdge power optimizer inputs.
IMPORTANT SAFETY FEATURE:
As long as the power optimizers are unconnected to the inverter and the inverter is
OFF, the power optimizers will output a safe 1V voltage during installation.
WARNING!
Make sure that the Plus (+) and the Minus (-) connector cables are firmly and totally
inserted.
IMPORTANT NOTE:
Be sure to record power optimizer serial numbers during their installation, as this
information may be required later for troubleshooting.
The SolarEdge Monitoring Portal can be used to access SolarEdge site information, as
described in the Step 4, Reporting and Monitoring Installation Data section on page 38.
SolarEdge Installation Guide – MAN-01-00057-2.0
Connecting Power Optimizers
► To connect these power optimizers to the PV modules:
The input connectors are shown in the figures above. The output connectors
are in the middle of each side.
Step 3, Connecting Power Optimizers
in Strings
Power optimizers must be connected in series in order to construct strings.
The full string can either be directly connected to the inverter or connected in
parallel to another strings and then together they are connected to the
inverter.
You can construct and connect in parallel strings of unequal length, meaning
the number of power optimizers in each string does not have to be the same.
The power optimizer output cables are labeled + and –.
Connect the Plus (+) connector of the output wire of the first power optimizer
in the string to the Minus (-) connector of the second power optimizer in the
string. Repeat this step for each power optimizer in the string. This procedure
is similar to the standard procedure for connecting PV modules.

SolarEdge Installation Guide – MAN-01-00057-2.0
Verifying Proper Power Optimizer
Connection
► To verify proper power optimizer connection:
Make sure the PV modules are exposed to sunlight during this process.
Otherwise, the power optimizers may not be on.
Verify each string individually before connecting it to the other strings or to
the inverter.
Each power optimizer connected to a PV module initially produces a safe
voltage of 1 V. A string with properly connected power optimizers should
produce 1 V per power optimizer in the string. For example, if 10 power
optimizers are connected in a string, then 10 V should be produced. Use a
voltmeter with at least 0.1V measurement accuracy to verify that the total
voltage produced is in accordance with the number of power optimizers in
the string.
If 0 V is measured for the string, check for a disconnection of the outputs
of one of the power optimizers.
If the voltage is lower than the quantity of power optimizers (for
example, 9 V when 10 power optimizers are connected), verify whether
one or more of the power optimizers are not connected, meaning they
were skipped during the string connection process. If they are all
connected, verify whether one or more of the PV modules is not
connected properly to its power optimizer.
If the voltage is too high, then apply the CAUTION below.
photovoltaikforum.com
Page 19
Installing the Power Optimizers
19
CAUTION:
If the measured voltage is too high, the installation may not have a safe low
voltage. PROCEED WITH CARE!!
Please note that a deviation of up to 2V for a full string is considered
normal.
A voltage that is higher than the quantity of power optimizers may be
caused by one of the following reasons:
An extra power optimizer is connected in the string.
The output of a PV module may be connected in the string instead of the
output of a power optimizer.
A malfunction of one of the power optimizers.
Perform the following if the total string voltage is too high:
Verify that only power optimizers are connected in the string and that no
PV module outputs are connected without a power optimizer.
Disconnect the wires that connect the power optimizers in the string.
Measure that there is 1V safety voltage for each individual power
optimizer in order to locate the power optimizer that does not output the
proper 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 removing the
malfunctioning power optimizer.
IMPORTANT SAFETY FEATURE:
After a PV module is connected to the power optimizer, the power optimizer
outputs a safe voltage of 1 V. We suggest verifying this output for the first
few power optimizers that you connect in order to verify their proper
connection. Take note that if you use a tracker, the power optimizer will turn
ON only if the tracker is tracking the sun and at least 2 W of power are
provided by the PV module.

Step 4, Recording Installation
Information
Be sure to record power optimizer serial numbers during their installation, as this
information may be required later for troubleshooting, and is necessary for proper
physical layout on the monitoring website.
The serial number(s) of the inverter(s) must be specified in order to open a new
site.

IMPORTANT SAFETY FEATURE:
All SolarEdge inverters incorporate a certified internal Residual Current Device (RCD)
in order to protect against possible electrocution and fire hazard in case of a
malfunction in the PV array, cables or inverter.
SolarEdge Installation Guide – MAN-01-00057-2.0
Residual Current Device
An external RCD is required in some countries. In these cases, the installer must
check which type of RCD is required by the relevant electric code. SolarEdge
recommends using a type-A RCD. The recommended RCD value is 100mA
or 300mA unless a lower value is required by the specific local electric codes.
When required by local regulations, the use of an RCD type B is permitted.
In installations where the local electric code requires the use of a lower leakage
RCD, the discharge current may trip the RCD. The following steps can be taken
in order to avoid this problem:
1 It is important to select an appropriate RCD in order to ensure proper
operation of the installation. Although the RCD used in such cases is a 30mA
RCD, it may still trip at 15mA (according to IEC 61008). Good quality RCDs
will trip at a higher value.
2 Configure the trip voltage of the inverters’ internal RCD to a lower current
than the trip current of the external RCD. The internal RCD may still trip if
the current is higher than the allowed current, but because the internal
inverter RCD automatically resets when the residual currents are low it does
not require a manual reset. You may consult with the SolarEdge support
center for assistance with this issue.
3 Certain PV modules (with low capacitance leakage to the frame) are
preferable.
Refer to the SolarEdge Application Note RCD Selection for SolarEdge Inverters
for a full discussion of the subject.

Step 2, Pairing Power Optimizers to the Inverter, page 35
Step 3, Verifying Proper Operation, page 37
Step 4, Reporting and Monitoring Installation Data, page 38
Step 1, Activating the System
This section describes how to perform the initial activation stages of the
SolarEdge system.
These stages are preformed after the inverter and power optimizers have been
installed and the power optimizers have been connected to the inverter.
► To activate the SolarEdge installation:
1 Power OFF the inverter by turning off the ON/OFF switch at the bottom of
the inverter and the DC switch (if exists).
2 Turn on the AC to the inverter. The following message appears on the
inverter’s LCD panel:

NOTE:
A measurement error on the inverter LCD of ±3 V is OK.
NOTE:
If the LCD panel shows 0 V:
Verify that the PV modules are are not shaded or otherwise obstructed.
Check for proper power optimizer, string and DC input connection.
Verify the correct polarity of the DC input connection.
WARNING!
Verify that the ON/OFF indicator on the LCD panel, described above, reads OFF.
SolarEdge Installation Guide – MAN-01-00057-2.0
3 If the site is installed with an external DC switch between the power
optimizers and the inverter(s), then turn it ON.
4 Verify that P_OK appears, which indicates a connection to the power
optimizers. The number 0 indicates that no power optimizer has been paired
to this inverter. If you are re-pairing the power optimizers and inverters, the
number indicates the number of power optimizers that have been paired in
the past. If P_OK does not appear, check the power optimizer, strings and
DC input connections.
5 If the inverter is connected to the SolarEdge Monitoring server, verify that
S_OK appears. This denotes that the connection to the server is successful.
6 Verify that the Vac [v] on the LCD panel specifies the grid’s correct AC
output voltage, in Volts.
7 Verify that the Vdc [v] on the LCD panel specifies the DC input voltage, in
Volts. There should be a safety voltage of 1 V for each power optimizer
connected to the inverter.
8 Verify that Pac [w] on the LCD Panel specifies 0 as the AC output power, in
Watts. This is because the inverter is still off.

Step 2, Pairing Power Optimizers to the
Inverter
After all connections are made, all the power optimizers must be logically paired
to their inverter before they can start working with it. This step describes how to
pair power optimizers to the inverter, meaning to assign each inverter to the
power optimizers from which it will produce power.
► To pair the power optimizers to the inverter:
1 Turn the ON/OFF switch at the bottom of the inverter to OFF. Press and hold
down the inverter’s LCD Light button for about 10 seconds. The following
screen is displayed:
Continue to hold for five seconds more and you will see this screen:
2 Turn the ON/OFF switch at the bottom of the inverter to ON within five
seconds. If you do not turn ON the inverter ON/OFF switch within five
seconds, the inverter then exits pairing mode.
The following screen is then displayed indicating that the inverter is
performing the process of pairing and is assigning power optimizers to the
inverter.
This message displays a countdown of the seconds until it completes the
pairing process. If pairing fails, an error is displayed. This error appears only

regulations (the inverter LED flickers green). While the inverter is in Standby
mode, the following message is displayed:
During this time, the inverter monitors the grid and verifies correct grid
voltage and frequency. This message indicates how many seconds remain
until the inverter will be in Production mode. This amount of time is in
accordance with the regulations of each country, and is typically between
three to five minutes.
The inverter then automatically goes to Production mode and produces power
(the inverter LED is steady green).

Step 3, Verifying Proper Operation
After the proper wake-up delay time is over, the following message appears on
the inverter’s LCD panel:
► To verify proper operation:
1 Verify that the inverter LED is steady green.
2 Verify that the ON/OFF indicator on the LCD panel, described above, reads ON.
3 Verify that P_OK appears to indicate a connection to the power optimizers.
Also, verify that S_OK appears, if the inverter is connected to the SolarEdge
Monitoring Server.
4 Verify that the total number of power optimizers connected to the inverter
appears next to the P_OK indicator on the LCD panel. If this number is too
low, then it may mean that one or more of the power optimizers are not
connected properly or the pairing process may have not been completely
successful, for example due to complete shading of one of the modules or
insufficient sunlight during the pairing process.
5 Verify that the Vac [v] on the LCD panel specifies the grid’s correct AC
output voltage in Volts.
6 Verify that the Vdc [v] on the LCD panel specifies the DC input voltage in
Volts, which should be between 250 V and 450 V in the single phase inverter
and between 550 V and 950 V in the three phase inverter.
7 Verify that Pac [w] on the LCD Panel specifies the total AC output power
produced, in Watts.

Step 4, Reporting and Monitoring
Installation Data
The SolarEdge Monitoring Portal enables you to access SolarEdge site
information, as described in the SolarEdge Monitoring Portal User Guide, as well
as receive up-to-date information from the installation site for viewing in a
physical or logical view.
After a site is opened in the SolarEdge Monitoring Server, you can access all the
monitored data about that site.
► To register a new site, go to:
http://monitoring.solaredge.com/
The serial number(s) of the inverter(s) must be specified in order to open a new
site.
The SolarEdge Monitoring Server also enables you to display a logical and
physical schematic layout of the installed power optimizers, as follows:
Logical Layout: Shows a schematic logical layout of the components in the
fields, meaning inverters, clusters, strings and modules and their electrical
connectivity. This view enables you to see a logical view of 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 fields, meaning inverters, clusters, strings and modules and their electrical
connectivity. This view enables you to see a physical bird’s eye view of the
installation site showing which modules are connected in each string, which
strings are connected to each inverter and so on.
This window enables you to:
View the latest performance of specific components.
Find underperforming components, such as modules, by comparing their
performance to that of other components of the same type.
Pinpoint the location of alerted components.
See how components are connected to each other.
In order to enable the SolarEdge Monitoring Portal to show the strings and the
physical location of power optimizers, you may first supply the physical and
logical mapping of the installed power optimizers.
photovoltaikforum.com
Page 39
Commissioning the Installation
39
IMPORTANT NOTE:
Even if you do not report the physical and logical mapping of the installed power
optimizers to SolarEdge, the SolarEdge Monitoring Portal will still show the logical
layout indicating which power optimizers are connected to which inverters. However, it
will not show strings or the physical location of power optimizers.
IMPORTANT NOTE:
Be sure to record power optimizer serial numbers during their installation, as this
information may be required later for troubleshooting.
SolarEdge Installation Guide – MAN-01-00057-2.0
This process prepares the SolarEdge Monitoring Portal for receiving
up-to-date information from the installation site and for displaying it in a physical
or logical view.
The inverter may be connected to the SolarEdge Monitoring Server via a LAN or
an external SolarEdge GSM modem connected to the RS232 port. Alternatively,
you can connect the inverter to another inverter that is already connected to the
server.
The inverter-to-inverter connection is made by an RS485 bus or a ZigBee modem.
This connection enables the inverters to send the latest data collected from the
power optimizers and inverters to the SolarEdge Monitoring Server.
If the inverter is properly connected to the internet, as described in the Step 3,
Verifying Proper Operation section on page 37, then the S_OK appears in the
inverter’s LCD screen.
Providing Installation Information
iPhone Site Mapper
SolarEdge provides an iPhone Site Mapper that helps you collect information
about your installation. This application leads you through the process of
scanning the labels on each inverter and power optimizer. It then helps you
transmit this collected information to SolarEdge’s Monitoring Portal (which was
described on the previous pages). The SolarEdge iPhone Mapping Application
can be downloaded from the SolarEdge website.

Setting Up Communication
Communication Dataflow
The SolarEdge site information can be accessed remotely using the SolarEdge
Monitoring Portal, as described in the SolarEdge Monitoring Portal User Guide.
In order to transfer monitoring data from a SolarEdge site to the SolarEdge
Monitoring Portal, a communication connection must be set up, as described in
this chapter. Communication setup is not required for power harvesting and is
needed only when using the monitoring portal.
Power optimizers send information to the SolarEdge inverter via DC lines. No
added wires or configurations are required for this purpose. The inverter sends
this information to the SolarEdge Monitoring Server through the Internet. The
sections below describe how to set up this connection.
Connector Panel
The connector panel on the inverter appears as shown below:

Creating an RS485 Bus Connection
The RS485 option enables you to create a bus of connected inverters. Using this
option, inverters are connected to each other in a chain, meaning the first inverter
in the chain is connected to the next inverter in the chain via its RS485 connector.
The first inverter in the chain and the last inverter in the chain must be terminated.
Figure 27: Example of RS485 Bus Connection
Each inverter must be connected according to the instructions below.
► To connect the RS485 communication bus:
1 Open the cover of the inverter, as described in the Opening the Cover section
on page 27.
2 Using the user buttons, select the RS485 option under the Communication
Bus menu, as described in the Configuring the Inverter Using the LCD

4 An inverter has either RJ45/RJ11 connectors or block terminal connectors for
communication.
If the inverter has RJ45/RJ11 communication connectors, then connect as
follows:
The RS485 bus uses a three-wire cable and a six-wire RJ11 connecter
(also known as RJ25). Insert the wire via one of the small cable glands.
The glands come from the factory pre sealed. Removal of the sealing is
required in order to insert the cable.
After inserting the wire, crimp a connector using a standard telephone
wire crimper. Two pins (numbered 2 and 3) must be connected. The two
wires must both belong to the same twisted pair, which is usually
indicated by similarly colored wire. In addition, a grounding wire that is
connected to pin number 6 must also be connected. For this purpose, you
can use any remaining wire of the telephone cable. The wiring on the
next inverter should be the same.
Figure 28: Crimping the Wires
Connect the RS485 cable connector to either of the RS485 plugs on
boards in the inverter.
Connect the other end of the RS485 cable of the first inverter through the
gland to the RS485 connector on the board of the next inverter in the
chain, as described above.

Disconnect the DC inputs.
For each DC string,
measure the DC voltage
between DC- and GND and
DC+ and GND with a
1Kohm resistor in parallel
to the volt meter. If a
voltage higher than 2 V is
measured, then the fault is
in this string.
Do not connect strings with

NOTE:
SolarEdge does not provide the screws, nuts or washers because the required sizes
and lengths vary for different racks.
CAUTION:
Before installing directly on the module or module frame, first consult the module
manufacturer for information about the proper positioning and its impact on the
module warranty.
CAUTION:
Do not drill through the power optimizer or through the mounting holes. The strong
vibrations created by the drill can damage the power optimizer.

Specifications
This appendix presents the mechanical specifications for the SolarEdge power
optimizers.
Use M6 (1/4”) screws and washers to secure the power optimizer units to the
racking.
Mark all mounting hole locations.
Each power optimizer must be attached to the rack using both mounting

Safe DC

WARNING!
The Safe DC voltage is only guaranteed when using modules of up to:
95Voc when using the single phase inverter
70Voc when using the three phase inverter
SolarEdge Installation Guide – MAN-01-00057-2.0
Appendix D
Safe DC
When AC supply to the inverter is shut off, by shutting off the AC breaker at the
site, or when the inverter ON/OFF switch is turned to OFF, the DC voltage drops
to a safe voltage of 1V per optimizer.
The SolarEdge inverters are certified for compliance with IEC 60947-3:1999 +
Corrigendum: 1999 + A1:2001 + Corrigendum 1:2001 + A2:2005; DIN EN
60947-3; VDE 0660-107:2006-03; IEC 60364-7-712:2002-05 and DIN VDE
0100-712:2006-06 as a disconnection device for PV generators, meaning that they
can replace a DC disconnect.
In compliance with this standard, the disconnection mechanism operates as
follows:
Turn the inverter ON/OFF switch, located at the bottom of the inverter, to
OFF, or disconnect the AC by shutting off the AC breaker at the site.
The DC voltage displayed on the inverter LCD begins to decrease. If the AC
breaker was shut off, the LCD does not display. In this case, wait five
minutes.
When the DC voltage reaches a safe voltage then the PV connectors at the
input to the inverter can be disconnected. A galvanic separation then exists
between the PV array and the inverter.
The disconnection is safe even under single fault conditions.
