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.
Chapter 1: Introducing the SolarEdge Power Harvesting System 13
Three Phase System Installation Guide MAN-01-00057-4.1

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.

Chapter 1: Introducing the SolarEdge Power Harvesting System 15
Three Phase System Installation Guide MAN-01-00057-4.1

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

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-input-
connector-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).
For installation of frame-mounted power optimizers, refer to
http://www.solaredge.com/sites/default/files/installing_frame_mounted_
power_optimizers.pdf.
Chapter 2: Installing the Power Optimizers 17
Three Phase System Installation Guide MAN-01-00057-4.1

The steps in this chapter refer to module add-on power optimizers. For smart
modules, start from Step 3: Connecting Power Optimizers in Strings on page
21 Step 3: Connecting Power Optimizers in Strings on page 21 Also refer to the
documentation supplied with the smart modules.
The power optimizer can be placed in any orientation.
If connecting more modules than optimizer inputs in parallel, use a branch
cable. Some commercial power optimizer models have a dual input.
Position the power optimizer close enough to its module so that their cables
can be connected.
Make sure to use power optimizers that have the required output conductor
length:
Do not use extension cables between a module and a power optimizer,
between two modules connected to the same optimizer, or between two
optimizers other than in the cases specified below.
You can use extension cables between power optimizers only from row
to row, around obstacles within a row, and from the end of the string to
the inverter, as long as the maximum distance is not exceeded.
NOTE
The total conductor length of the string (excluding
power optimizers’ conductors; including home runs and
necessary extensions between optimizers) should not
exceed the following:
Inverter model Total conductor length ( from DC+
to DC- of the inverter)
Three phase up to
SE25K 1000 ft. /300 m
Three phase SE25K
and above 2300 ft./ 700 m
Use at least 11 AWG/ 4 mm² DC cables.
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
-Three Phase System Installation Guide MAN-01-00057-4.1
18 Installation Guidelines

the minimum optimizers are connected to unshaded modules, add more
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.
Figure 2: Power optimizer clearance
When installing modules in a confined space, for example, if installing Building-
integrated photovoltaic (BIPV) modules, ventilation measures may be needed to
ensure the power optimizers are not be exposed to temperatures outside their
specifications.
