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
Chapter 1: Introducing the SolarEdge Power Harvesting System 9
EV Charging Single Phase Inverter Guide MAN-01-00583-1.5

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/P switch 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.
Two types of power optimizers are available:
Panel Module Add-on power optimizer – connected to one or more modules
Smart modules - the power optimizer is embedded into a module
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.
EV Charging Single Phase Inverter
The EV Charging Single Phase Inverter (referred to as “inverter”throughout) 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).
The EV Charging Single Phase Inverter is designed to provide reliable and economical
charging of an electric vehicle (EV). It provides Mode 3 EV charging from both the grid
and the PV system, and is designed to work with all plug-in vehicles with J1772 (Type 1)
socket and (Type 2) IEC62196 sockets.
An EV Charger cable (ordered separately)is required for EV charging:

The EV Charger Cable connects the EV plug to the inverter
The wall mounted EV Charger cable holder is used for hanging the EV Charger cable
and plug, protecting the plug from rain when not plugged into the vehicle, and
provides strain relief for the inverter when the cable is pulled.



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
module’ 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
For the minimum and maximum number of power optimizers in a string (string
length), see 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#/.
The length of home-run cables from the first and last power optimizer to the
inverter (total cable length) may not exceed the following values:
Single Phase Inverters Three Phase Inverters
All - 1000 ft. /300 m SE25K and below - 1000 ft. /300 m
Above SE25K - 2300 ft. /700 m
EV Charging Single Phase Inverter Guide MAN-01-00583-1.5
16 Installation Guidelines

Do not use extension cables between a module and a power optimizer, between
two modules connected to the same power optimizer, or between two power
optimizers other than in the following cases:
Power optimizers with the 4-type suffix in their part number (Pxxx-4xxxxxx) -
extension cables of up to 16 m can be installed per optimizer (8 m for DC+ and
8 m for DC-).
Power optimizers manufactured starting from working week 42, 2019, as
indicated in the serial number (Example:S/N SJ5019A-xxxxxxxx - working week
50, 2019) - extension cables of up to 16 m can be installed per power optimizer
(8 m for DC+ and 8 m for DC-).
Extension cables can be installed between power optimizers only from row to
row, around obstacles or pathways within a row, and from the end of the
string to the inverter, as long as the total cable length is not exceeded.
For connecting power optimizers to the inverter, use cables with a minimum cross-
section of 11 AWG/ 4 mm² DC cables.
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.
The power optimizer can be placed in any orientation.
If connecting more modules than power 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.
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
power optimizers are connected to unshaded modules, add more power optimizers
to the string.
Chapter 2: Installing the Power Optimizer 17
EV Charging Single Phase Inverter Guide MAN-01-00583-1.5

To allow for heat dissipation, maintain clearance as specified below.
Figure 3: 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.
Step 1: Mounting the Power Optimizers
For each of the power optimizers(1):
1. Determine the power optimizer mounting location and use the power
optimizer mounting brackets to attach the power optimizer to the
support structure . It is recommended to mount the power optimizer
in a location protected from direct sunlight. For frame-mounted
power optimizers follow the instructions supplied with the optimizers,
or refer to https://www.solaredge.com/sites/default/files/installing_frame_
mounted_power_optimizers.pdf.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Drilling vibrations may damage the power optimizer and will void the
warranty. Use a torque wrench or an electric drill with adjustable clutch that
meets the mounting torque requirements. Do not use impact drivers for
mounting the power optimizer.
Do not drill through the power optimizer or through the mounting holes.
(1)Not applicable to smart modules.
