roducing the SolarEdge Power
What is the SolarEdge Power Harvesting Solution?
The Sol arEdge p ower 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.
Three 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, OP4 80-IV, PB250-AOB and PB350-AOB.
Mo dule Embedded So luti on (C SI), is supplied embedded into a PV
module.

Figure 1: Ad d-On Box Solution
Single Phase Inverter
The Single Phase Inverter efficiently converts 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 inverter also receives the monitoring data from each power optimizer and transmits it to a central server (called the Monitoring Server) through an Etherne t network to an external modem connection.

Step 3, Connecting Power Optimizers in Strings
Power optimizers must be co nnected in series in order to c onstruct strings.
TURE:
The full string can be directly connected to the inverter or connected in
parallel to other strings and then 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.

Verifying Proper Power Optimizer Connection
► To verify pr oper power optimizer connection:
Ma ke sure the PV modules are exposed to sunlight during this pro cess.
Otherwise, the power optimizers may not be powered up.
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 accurac y to ver ify that the total voltage produced is in accordance with the number of power optimizers in the string.
• If 0 V is measured for the s t ring, check for a disconnection of the outputs
of one of the power optimizers.
• If the voltage is lower than the quantity of po wer optimizers (for
example, 9 V when 10 p ower 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 vol tage is too high, then apply the CAUTION below.
Installing the Power Optimizers
CAUTION:
If the measured voltage is too high, the installation may not have a safe low voltage. PROCEED WIT H CARE!!
Please note that a deviation of up to 2V for a normal.
A voltage that is higher than the quantity of power optimizers may be caused by one of the following reasons:

Installing the AC/DC Safety Switch
What is the A C/DC Safety S witch?
The AC/DC Safety Switch is a manually operated switch for disconnecting the AC and DC power of a SolarEdge inverter in a SolarEdge power harvesting system.
The AC/DC Safety Switch is installed on the bottom of each inverter. AC and DC cables run through i t and connect to the inverter.
The AC/DC Safety Switch opens all ungrounded conductors of the circuit to which it is connected in compliance with the National Electric Code, and specifically NEC690.35, which addresses ungrounded PV arrays. The AC/DC Safety Switch is rated to the operating condition of the inverter (32ADC, 600VDC and 25 continuous AAC 277/240/208VAC).
Two types of switches are available, one with part number DCD-1ph-US-A and the other with part number DCD-1ph-US-B. The specifications for each of these two switches are described on page 52. Both safety switches have similar functionality and installa tion methods.

IMPORTANT SAFETY FEATURE:
Detection, indication and cease power export per NEC 690.35 (C). All SolarEdge inverters incorporate a
Interrupter (GFCI) in order to protect against possible electrocuti on and fire hazard in case of a malfunction in the PV array, cables or inverter.
Détection, indication et arrêt de la génération d’électric it é, confo rmément à la norme NEC 690.35 (C).

55
Ground Fault Circuit Interrupter
certified internal Ground Fault Circuit
An external GFCI is required in some countries. In these cases, the installer must check which type of GFCI is required by the relevant electric code.
SolarEdge recommends using a type-A GFCI. The recommended GFCI value is 100mA or 300mA unless a lower value is required by the specific local electric codes.
In installations where the local electric code requires the use of a lower leakage GFCI, the discharge current may trip t he GFCI. The following steps can be taken in order to avoid this problem:
1 It is important to select an appropriate GFCI in order to ensure proper
operation of the installation. Although the GFCI used in such cases is a 30mA GFCI, it may still trip at 15mA (according to IEC 61008). Good quality GFCIs will trip at a hi gher value.
2 Configure the trip current of the in ver te r s’ internal GFCI to a lower current
than the trip current of the external GFCI. The internal GFCI may still trip if the current is higher than the allowed current, but because the internal inverter GFCI 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 panels (with low capacitance leakage to the frame) are preferable.
Refer to the SolarEdge Application Note GFCI Selection for Single-Phase Inverters for a full discussion of the subject.

Step 1, Activating the System
This section describes how to perform the initial activation stages of the SolarEdge syste m.
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 install at ion:
1 Power OFF the Single Phase I nverter by turning o ff the ON/ OFF switch a t
the bottom of the inverter.
2 Turn on the AC at the breakers and at the AC/DC safety switch. 3 If the site is installed with an external DC switch betwee n the power
optimizers and the inverter (s), then turn it ON. A message similar to the following message appears on the inverter’s LCD panel:
4 Verify that P_OK appears, which indicates a connection to the power
optimizers, and that at least o ne power optimizer is sending monitoring data. 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 inp ut voltage, in
Volts. There should be a safety voltage of 1 V for each power optimizer connected to the inverter.

Verify that the PV modules are are not shaded or otherwise obstructed. Check for proper power optimizer, string and DC input connection.
8 Verify that Pac [w] on the LCD panel specifies 0 as the AC outp ut 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. T his st e p 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 t he bottom of the inverter to off. Press and hold
down the inverter’s LCD Li ght butto n for about 10 seconds. The following screen is displayed:

If the inverter starts con ver ting after the initial connectio n to the AC, the inverter then goes into Sta ndby mode until enough power is generated (the inverter LED flic kers green). While the inverter is in Stand by mode, the following message is displayed:
During t his time, t he inverter monitors the grid and ver ifies correct grid voltage and frequency. This message indicate s 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 op era t ion:
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 .
Commissioning the Install atio n
NOTE:
It can take up to 15 minutes for all power optimizers to transmit their telemetries and to be counted on the LCD screen.
NOTE:
Take note of the serial # on the inverter’s sticker and on its warranty card. This information is used in the SolarEdge Monitoring Portal to identify t and is needed to open a new site in the monitoring portal.
61
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.
7 Verify that Pac [w] on the LCD Panel specifies the total AC output power
produced, in Watts.

IMPOR TANT NOTE:
Even if you do not report the physical and logical mapping of the installed power optimizers to SolarEdge, the SolarEdge Monitoring Portal will st ill show the logical layout indicating which power optimizers it will not show strings or the physical location of power optimizers.
62
The Sol arEdge Monitoring Server also e nables you to display a logical and physical schematic la yo ut o f t he installed power optimizers, a s follows:
Logical Layout: Shows a schematic logical layout of the co mponents in the
fields, meaning inverters, clusters, strings and panels a nd their electrical connectivity. T his view enables you to s ee a logical view o f which pa nels 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 panels and their electrical connectivity. T his view enables you to s ee a physical bird’s e ye view of the installation site sho wing which panels are connected in each string, which strings are connected to each inverter and so on.
This window enables you to:
Vie w the latest performance of specific components. Find underp erforming components, such as panels, by comparing their
performance to that of other components of the same type.
Pinpoint the location of alerted c omponents. See how components are connected to each other.
In order to enable the SolarEdge Monitoring Portal to show the strings and physical location of power optimizers, you may first report the physical and logical mapping of the insta lled power optimizers by mai l, e mail or fax to SolarEdge. SolarEdge will then upload this information to the SolarEdge Monitoring Server .

SolarEdge provides an iPhone Site Mapper that helps yo u co lle c t information about your installation. This application leads you through the process of photographing 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.
Registering Installation Infor m ation on the SolarEdge Website
Register the site using the registration form available from the follo wing link:
http://www.solaredge.com/groups/site-registration. Fill out all required
information in the form, which includes information about your installation, as well as details about its logical and physical mapping.
If you wish, you can also supply the following information on the form:
Logical Mapping: Showing which power optimizer is loca te d in which
string and in which order. Y ou can specify the logi cal mapp ing of the strings and power optimizers, as follows: P.Inverter_number.String_number.power optimizer_number. For example, the third power optimizer connected to a power optimizer in the second string in the #4 inverter in the installation is represented as P.4.2.3.
Physic al Mapping: Showing a physical map (a drawing) of the location of
each power optimizer in the installation. Use the SolarEdge Physical Layout Template available on the SolarEdge website or the site mapper mentioned above.
The logi cal and physical mapping can b e used in the future for debugging a problem using the SolarEdge Monitoring Portal.
