Chapter 1: Introducing the SolarEdge Power Harvesting System 13

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.

Figure 1: The SolarEdge power harvesting system components

Power Optimizer

The 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 ON/OFF switch is turned OFF

The safety switch on the DC Safety Unit is turned OFF

The inverter AC breaker is turned OFF

Each power optimizer also transmits module performance data over the DC power line
to the inverter.

Three Phase System Installation Guide MAN-01-00057-4.1

14  Inverter

Two types of power optimizers are available:

Module Add-on power optimizer – connected to one or more modules

Smart modules - the power optimizer is embedded into a module

Inverter

The 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 monitoring platform; requires Internet connection).

Some inverters are available with an optional DC Safety Unit. The DC Safety Unit has a
manually operated switch for disconnecting the DC power of a SolarEdge system.

The DC Safety Unit is located below the inverter and is connected to the inverter with
AC and DC wires.

Monitoring Platform

The monitoring platform enables monitoring the technical and financial performance of
one or more SolarEdge sites. It provides past and present information on the system
performance both at the system and module levels.

Installation Procedure

The following is the procedure for installing and setting up a new SolarEdge site. Many

of these also apply to modification of an existing site.

Safety

The following notes and warnings apply when installing the power optimizers. Some of

the following may not be applicable to smart modules:

WARNING!
When modifying an existing installation, turn OFF the inverter ON/OFF switch,

the Connection Unit and the AC circuit breaker on the main AC distribution
panel.

CAUTION!
Power optimizers are IP68/NEMA6P rated. Choose a mounting location where

optimizers will not be submerged in water.

CAUTION!
This unit must be operated according to the operating specifications provided

with the unit.

CAUTION!
Cutting the power optimizer input or output cable connector is prohibited and

will void the warranty.

CAUTION!
All PV modules must be connected to a power optimizer.
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.

-Three Phase System Installation Guide MAN-01-00057-4.1

Chapter 2: Installing the Power Optimizers 17

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. To
ensure mechanical compatibility of the power optimizers’ connectors with the PV
modules’ connectors 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 module 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.

For more information, refer to

https://www.solaredge.com/sites/default/files/optimizer-input­connector-compatibility.pdf



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.

Installation Guidelines

The minimum and maximum string length guidelines are stated in the power
optimizer datasheets. Refer to the Designer for string length verification. The
Designer is available on the SolarEdge website at

https://www.solaredge.com/products/installer-tools/designer#/.

Frame-mounted power optimizers are mounted directly on the
module frame , regardless of racking system (rail-less or with rails).

optimizers to the string.

To allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between
the power optimizer and other surfaces, on all sides except the mounting
bracket side.

Step 4: Verifying Proper Power Optimizer Connection

When a module is connected to a power optimizer, the power optimizer outputs a safe

voltage of 1V (±0.1V). Therefore, the total string voltage should equal 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 PVmodules are exposed to sunlight during this process. The power

optimizer will only turn ON if the PVmodule provides at least 2W.

In SolarEdge systems, due to the introduction of poweroptimizers 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 system’s string voltage and

current, refer to the

available on the SolarEdge website at:

https://www.solaredge.com/sites/default/files/isc_and_voc_in_solaredge_sytems_

technical_note.pdf .

To verify proper power optimizer 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.

NOTE
Since the inverter is not yet operating, you may measure the string voltage and

verify correct polarity on the DC wires inside the DC Safety Unit.

ON/OFF switch: Turning this switch ON (after the power optimizers are paired
with the inverter) starts the operation of the power optimizers, enables power
production and allows the inverter to begin exporting power to the utility grid.
Turning it OFF reduces the power optimizer voltage to a low safety voltage and
inhibits exportation of power. When this switch is OFF, the inverter control
circuitry remains powered up.

NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited

because the inverter has no transformer. Grounding (earth ground) of module
frames and mounting equipment of the PV array modules is acceptable.

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.

Connect the DC connectors of each string to the DC+ and DC- connectors .

Selecting a Residual Current Device (RCD)

 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. There are 2 trip thresholds
for the RCD as required for certification (DIN VDE 0126-1-1). The default value
for electrocution protection is 30 mA, and for slow rising current is 300 mA.

-Three Phase System Installation Guide MAN-01-00057-4.1

Chapter 4: Connecting the AC and the Strings to the Inverter 35

If an external RCD is required by local regulations, check which type of RCD is required
for the relevant electric code. Install the residual-current device (RCD) in accordance
with the applicable local standards and directives. SolarEdge recommends using a type­A RCD. The recommended RCD value is 100 mA or 300 mA unless a lower value is
required by the specific local electric codes. For extended power three phase inverters
(SE25K, SE27.6K and SE33.3K) an RCD value of 300 mA should be used. When required
by local regulations, the use of an RCD type B is permitted.

NOTE
For multiple inverters, an RCD per inverter is required.

In installations where the local electric code requires an RCD with a lower leakage
setting, the discharge current might result in nuisance tripping of the external RCD. The
following steps are recommended to avoid nuisance tripping of the external RCD:

Select the appropriate RCD for correct operation of the installation: An RCD with
a rating of 30 mA may actually trip at a leakage as low as 15 mA (according to
IEC 61008). High quality RCDs will typically trip at a value closer to their rating.

Configure the trip voltage of the inverter's internal RCD to a lower value than
the trip current of the external RCD. The internal RCD will 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 saves the manual
reset.

The Monitoring Platform

The monitoring platform provides enhanced PV performance monitoring and yield
assurance through immediate fault detection and alerts at the module , string and
system level.

Using the platform, you can:

View the latest performance of specific components.

Find under-performing components, such as modules, by comparing their
performance to that of other components of the same type.

Pinpoint the location of alerted components using the physical layout.

The monitoring platform enables accessing site information, including up-to-date
information viewed in a physical or logical view:

Logical Layout: Shows a schematic tree-layout of the components in the
system, such as: inverters, strings, modules, meters and sensors, 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: Provides a bird's eye view of the actual placement of modules
in the site, and allows pinpoint issues to the exact location of each module on a
virtual site map.

If you do not report the mapping of the installed power optimizers, the monitoring
platform 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 monitoring platform includes a built-in help system, that guides you
through the monitoring functionality.

For more information, refer to https://www.solaredge.com/products/pv-

CARE! A deviation of ±1%
per string is reasonable.

Appendix A: Errors and Troubleshooting 83

Extra power optimizer(s) connected in the string
(not applicable to smart modules).

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 (not applicable to
smart modules).

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.
Power optimizer(s) malfunction.

1. Disconnect the wires connecting the power

optimizers in the string.

2. Measure the output voltage of each power

optimizer to locate the power optimizer that
does not output 1V safety voltage. If a
malfunctioning power optimizeris located,
check its connections, polarity, module, and
voltage.

3. Contact SolarEdge Support. Do not continue

before finding the problem and replacing the
malfunctioning power optimizer. If a
malfunction cannot be bypassed or resolved,
skip the malfunctioning power optimizer,
thus connecting a shorter string.

Appendix D: SafeDC™

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 the following standards as
disconnection devices for PV generators, meaning that they can replace a DC
disconnect:

IEC 60947-3:1999 + Corrigendum: 1999 + A1:2001 + Corrigendum 1:2001 +
A2:2005;

IEC 60364-7-712:2002-05

DIN VDE 0100-712:2006-06.

In compliance with these standards, the disconnection mechanism operates as follows:

Turn the inverter ON/OFF switch, located at the bottom of the inverter, to OFF, or

1.

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.

2. When the DC voltage reaches a safe voltage, the PV connectors at the input to the

inverter can be disconnected. A galvanic separation then exists between the PV
array and the inverter.

WARNING!
SafeDC complies with IEC60947-3 when installing the system with a worst case

SafeDC voltage (under fault conditions) < 120V.
The worst case voltage is defined as: Voc,max+ (String Length-1)*1V, where:

Voc,max = Maximum Voc (at lowest temperature) of the PV module in
the string (for a string with multiple module models, use the max value)

String Length = number of power optimizers in the string

Introduction

Inverters should be protected by circuit breakers. This document describes how to
determine which circuit breaker to use in three phase commercial installations.

Using Transformers in Commercial Three Phase Inverter Installations

Using transformers in a commercial installation is optional. In most cases a transformer
is used to connect the installation to the medium voltage power grid. The following
figure illustrates a typical transformer and commercial three phase inverter installation
topology.

Figure 43: Typical transformer and commercial three phase inverter installation topology

-Three Phase System Installation Guide MAN-01-00057-4.1

Appendix G: Determining the Circuit Breaker Size 99

There are many considerations for selecting the suitable transformer and its associated
current limiting devices such as circuit breakers and fuses. The considerations must
include at least the following:

The transformer should be designed for a typical PV system production profile:
high daytime loads with no loads at night.

The current limiting devices should protect the electrical circuits and the
inverters from the excess current created by an overload, or a short circuit. If a
short circuit or other overcurrent occurs, the current limiting devices should
block the current flow to the circuit, thus preventing damage to the electrical
circuits and the inverters.

The circuit breakers and the fuses should comply with the transformer
manufacturer recommendations and with the relevant sections in standards
such as IEC 60909, IEC 60364, UL 508A and NEC 2017.
Some manufacturers provide detailed information about the transformer short
circuit calculation procedure, and its effect on the selection of circuit breakers
and fuses at the different hierarchical levels of the installation topology (see

Figure 43

).

For an example of a calculation, refer to:

Guidelines on the Short Circuit Current Rating for Industrial Control Panels

Short-circuit current rating (SCCR) of industrial control panels

To ensure that the circuit breaker and fuses trip as expected, follow their
manufacturers' recommendations, especially with respect to the various de­rating considerations.

NOTE
Transformer procurement, installation, maintenance and support are the

responsibility of the installer. Damage to the inverter due to incorrect
transformer installation, or use of a transformer that is incompatible with the
SolarEdge system will render the SolarEdge warranty invalid.
