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.

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, OP480-IV, PB250-AOB and PB350-AOB.

Module Embedded Solution (CSI), is supplied embedded into a PV module.

Figure 1: Add-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 Ethernet network to an external modem connection.

Installing the Power Optimizers

Applicable Notes and Warnings

The following notes and warnings apply when installing the SolarEdge power optimizers:

WARNING:

Before performing these steps, turn OFF the Single Phase Inverter by turning off the

ON/OFF switch at the bottom of the inverter. All inverters in an installation site must be switched OFF in this manner.

Avant de faire ces étapes, éteignez l'onduleur monophasé en mettant sur OFF l'interrupteur ON/OFF situé au bas de l'onduleur. Tous les onduleurs sur un site d'installation doivent être etteints de la même manière.

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.

Pour installation à même le module ou la monture du module, consultez d'abord le fabricant du module sur la position et son impact sur la garantie du module.

CAUTION:

Unused connectors must be sealed with appropriate plugs (not provided). Leaving connectors exposed may be unsafe or create funcional problems in the installation and will void the warranty.

Les connecteurs non-utilisés doivent être scellés avec des bouchons (non-fournis).

Laisser des connecteurs exposés peut être dangereux ou peut créer des problèmes fonctionels lors de l’installation et par conséquent ne seront pas couvert par la guarantie.

Installing the Power Optimizers

16

SolarEdge Installation Guide – MAN-01-00002-1.6

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.

Les optimiseurs de puissance et onduleurs SolarEdge utilisent des connecteurs des fabricants suivants:

Multi Contact MC4

Amphenol H4

Tyco connecteur clé

Huber suhner Raddox

Les connecteurs du module doivent être mécaniquement compatibles avec les optimiseurs de puissance. Sinon, le système SolarEdge installé peut être dangereux ou causer des problèmes fonctionnels, tels que les défauts de terre, qui peuvent provoquer un arręt de l’onduleur.

Afin d'assurer la compatibilité mécanique entre les optimiseurs de puissance

SolarEdge et les modules auxquels ils sont connectés, il faut :

Utiliser des connecteurs identiques du même fabricant et du même type aussi bien pour les optimiseurs de puissance que pour les modules.

Vérifiez que les connecteurs sont compatibles de la manière suivante:

▪ Le fabricant du connecteur doit explicitement vérifier la compatibilité

avec le connecteur SolarEdge.

▪ Un rapport de test de tierce partie doit être effectué par l’un des

laboratoires externes indiqués ci-dessous:(TUV, VDE, Bureau Veritas UL,

CSA, Intertek), qui vérifiera la compatibilité des connecteurs.

Installing the Power Optimizers

17

SolarEdge Installation Guide – MAN-01-00002-1.6

NOTE:

The power optimizer is waterproof when the input and output cable connectors are mated, and has no need for shelter. Do NOT leave the optimizer exposed to water unless the connectors are mated. The power optimizer can be placed in any orientation, meaning there is no up side.

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.

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.

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 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 panels only. If under typical conditions fewer than eight modules will remain unshaded, add more PV modules.

Installing the Power Optimizers

18

SolarEdge Installation Guide – MAN-01-00002-1.6

Step 1, Mounting the Power

Optimizers

IMPORTANT NOTE:

Be sure to record power optimizer serial numbers and locations during their installation, as this information may be required later for troubleshooting, and is necessary for proper physical layout on the monitoring website.

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 (for the OP250-LV,

OP300-MV, OP400-MV, PB250-AOB and PB350-AOB models). Mark all mounting hole locations.

Each power optimizer must be attached to the rack using both mounting holes.

Drill the holes.

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.

Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation.

Les vibrations qui en résulteraient peuvent endommager la optimiseur de puissance.

Mount one power optimizer at each location using 5/16” screws and washers.

Verify that the power optimizer is securely attached.

Installing the Power Optimizers

19

SolarEdge Installation Guide – MAN-01-00002-1.6

WARNING!

The metallic enclosure of the power optimizer must have equipment grounding. Perform the following in order to properly ground the power optimizer enclosure. Grounding of the power optimizer can be performed in either of two ways:

L'enceinte metallique de la optimiseur de puissance doit être mise à la terre.

Suivre la procédure suivante afin de mettre l'enceinte de la optimiseur de puissance à la terre convenablement. La mise à la terre de la optimiseur de puissance peut s'accomplir par l'une des deux méthodes suivantes:

For mounting the power optimizer on a grounded rail, use the provided

5/16'' stainless steel star washer between the railing and the flat side of the mounting bracket. The star washer should break through the anodize coating of the railing to ensure low-resistive connection.

Pour le montage de l'optimiseur de puissance sur rail mis à la terre, utilisez la rondelle étoile en acier inoxydable 5/16'' fournie, entre le rail et le côté de la bretelle de montage non recouverte. La rondelle étoile doit traverser le revêtement anodisé du rail pour assurer une adhésion à basse résistivité.

For mounting the power optimizer on an un-grounded structure (such as a wooden structure), connect an equipment grounding conductor to the grounding terminal. The grounding terminal will accept a wire size of

6-14 AWG, and must be sized for equipment per NEC 250.122.

Pour le montage de l'optimiseur de puissance sur une structure non mise

à la terre (comme une structure en bois), connectez un conducteur de mise à la terre à la borne de mise à la terre. La borne de mise à la terre accepte une taille de fil de 6-14 AWG, et doit être dimensionné pour

équipement conforme au NEC 250.122.

Installing the Power Optimizers

20

SolarEdge Installation Guide – MAN-01-00002-1.6

Step 2, Connecting Each PV Module to a Power Optimizer

WARNING!

Before performing this step, turn OFF the Single Phase Inverter by turning off the ON/OFF switch at the bottom of the inverter and the DC 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.

Avant d'effectuer cette étape, éteignez l'onduleur monophasé avec le sectionneur ON/OFF en bas de l'onduleur et avec le sectionneur CA/CC. Tous les onduleurs d'une installation doivent être éteints de cette manière. Cette

étape est requise pour vérifier que les optimiseurs de puissance produisent une tension de sécurité de 1V pendant l'installation.

OP250-LV, OP300-MV and OP400-MV

Connecting Power Optimizers

To connect these power optimizers to the PV modules:

WARNING!

Verify that you have identified the inputs and outputs correctly. Do not connect PV modules to power optimizer outputs.

Vérifiez que vous avez identifié les entrées et sorties correctement. Ne pas connecter des modules PV aux sorties des optimiseurs de puissance.

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.

The input connectors are shown in the figures above. The output connectors are in the middle of each side.

Installing the Power Optimizers

23

SolarEdge Installation Guide – MAN-01-00002-1.6

Step 3, Connecting Power Optimizers in Strings

Power optimizers must be connected in series in order to construct strings.

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.

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.

WARNING!

Make sure that the Plus (+) and the Minus (-) connector cables are firmly and totally inserted.

Veillez à ce que les câbles de connexion Plus (+) et Moins (-) sont insérés fermement et jusqu'au bout.

IMPORTANT NOTE:

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 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 61.

Installing the Power Optimizers

24

SolarEdge Installation Guide – MAN-01-00002-1.6

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 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 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.

Installing the Power Optimizers

25

SolarEdge Installation Guide – MAN-01-00002-1.6

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.

Si la tension mesurée est trop élevée, l'installation pourrait ne pas avoir de basse tension de sécurité. PROGRESSEZ AVEC PRUDENCE!!

Notez qu'une déviation de jusqu'à 2V pour une chaine complete est considérée comme normale.

Une tension qui est supérieure au nombre de optimiseurs de puissance dans la chaine peut se produire pour les raisons suivantes:

Une optimiseur de puissance supplémentaire est connectée dans la chaine.

La sortie d'un module est connectée à la chaine au lieu de la sortie d'une optimiseur de puissance.

Une malfonction d'une optimiseurs de puissance.

Procédez comme suit si la tension de chaine est trop haute:

Vérifier que seulement des optimiseurs de puissance sont connectées à la chaine et que pas un seul module soit connecté directement à la chaine.

Débrancher les cables qui connectent les optimiseurs de puissance

à la chaine.

Installing the Power Optimizers

26

SolarEdge Installation Guide – MAN-01-00002-1.6

Mesurez que la sortie de chaque optimiseur de puissance génère un seul Volt de tension afin de localiser la optimiseur de puissance qui ne génère pas la bonne tension.

Si une optimiseur de puissance défectueuse est identifiée, vérifier ses connections, sa polarité, le module et la tension.

Si une optimiseur de puissance défectueuse ne peut pas être courtcircuitée ou réparée, sautez la optimiseur de puissance et connectez une chaine plus courte.

Ne pas continuer avant d'avoir trouvé le problème et retiré la optimiseur de puissance défectueuse.

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.

For more information about recording and monitoring installation data, see

page 61.

Installing the AC/DC Safety Switch

What is the AC/DC Safety Switch?

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 it 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 installation methods.

NEC 690.35 (C).

Tous les onduleurs SolarEdge intègrent un disjoncteur de fuite à la terre protégeant contre les risques d’électrocution et d’incendie en cas de dysfonctionnement des panneaux PV, des câbles ou de l’onduleur.

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 the 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 higher value.

2 Configure the trip current of the inverters’ 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.

SolarEdge Installation Guide – MAN-01-00002-1.6

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 Single Phase Inverter by turning off the ON/OFF switch at 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 between 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:

V a c [ v ] V D c [ v ] P a c [ w ]

2 3 0 . 7 1 4 . 1 0 . 0

P _ O K : 0 0 0 / 0 0 0 < S _ O K >

O F F

4 Verify that P_OK appears, which indicates a connection to the power optimizers, and that at least one 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 input voltage, in

Volts. There should be a safety voltage of 1 V for each power optimizer connected to the inverter.

NOTE:

A measurement error on the inverter LCD of ±3 V is OK.

Commissioning the Installation

58

SolarEdge Installation Guide – MAN-01-00002-1.6

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.

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.

WARNING!

Verify that the ON/OFF indicator on the LCD panel, described above, reads

OFF.

Vérifiez que l'indicateur ON/OFF sur le panneau d'affichage LCD décrit ci-dessus lit 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.

NOTE:

The power optimizer does not start producing power until it is paired with an inverter.

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:

K e e p h o l d i n g b u t t o n f o r p a i r i n g , r e l e a s e t o e n t e r m e n u . . .

R e m a i n i n g : 3 s e c

Commissioning the Installation

59

SolarEdge Installation Guide – MAN-01-00002-1.6

Continue to hold for five seconds more and you will see this screen:

P a i r i n g

T u r n S w i t c h T o O n

2 Turn on the inverter ON/OFF switch at the bottom of the inverter 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.

P a i r i n g

R e m a i n i n g [ S e c ] : 1 0 4

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 if the above steps were not followed. If an error appears, then follow the pairing steps again.

After commissioning succeeds, the following message is displayed:

P a i r i n g

P a i r i n g C o m p l e t e d

3 Since at this stage the ON/OFF switch at the bottom of the inverter is ON, the power optimizers start producing power and the inverter starts converting

AC.

WARNING!

After you turn ON the ON/OFF switch of the Single Phase Inverter, the DC cables carry a high voltage and the power optimizers no longer output a safe

1V output.

Après avoir mis l'interrupteur ON/OFF de l'onduleur monophasé sur ON, les câbles DC portent une haute tension et les optimiseurs de puissance ne génèrent plus la tension de sécurité de 1V.

Commissioning the Installation

60

SolarEdge Installation Guide – MAN-01-00002-1.6

If the inverter starts converting after the initial connection to the AC, the inverter then goes into Standby mode until enough power is generated (the inverter LED flickers green). While the inverter is in Standby mode, the following message is displayed:

W a k i n g U P . . .

R e m a i n i n g : 0 5 1 S e c

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:

V a c [ v ] V d c [ v ] P a c [ w ]

2 3 0 . 7 3 7 1 . 9 2 3 4 9 . 3

P _ O K : X X X / Y Y Y < S _ O K >

O N

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.

Commissioning the Installation

61

SolarEdge Installation Guide – MAN-01-00002-1.6

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.

NOTE:

It can take up to 15 minutes for all power optimizers to transmit their telemetries and to be counted on the LCD screen.

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.

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 this inverter and is needed to open a new site in the monitoring portal.

Congratulations! Your SolarEdge power harvesting system is now operational.

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, fill in the online form at http:/www.solaredge.com/groups/site-registration.

The serial number(s) of the inverter(s) must be specified in order to open a new site.

Commissioning the Installation

62

SolarEdge Installation Guide – MAN-01-00002-1.6

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 panels and their electrical connectivity. This view enables you to see a logical view of which panels 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. This view enables you to see a physical bird’s eye view of the installation site showing which panels 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 panels, 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 physical location of power optimizers, you may first report the physical and logical mapping of the installed power optimizers by mail, email or fax to

SolarEdge. SolarEdge will then upload this information to the SolarEdge

Monitoring Server.

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.

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 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.

inverter’s LCD screen.

Providing Installation Information

IMPORTANT NOTE:

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.

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 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 Information on the SolarEdge

Website

Register the site using the registration form available from the following 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 located in which string and in which order. You can specify the logical mapping 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.

Physical 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 logical and physical mapping can be used in the future for debugging a problem using the SolarEdge Monitoring Portal.

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.

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 four-wire telephone 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.

CAUTION:

If a gland is opened and not used, be sure to reseal it. Otherwise, it may affect the inverter’s functionality.

Si une glande est ouverte et non utilisée, assurez-vous de la refermer.

Sinon, cela pourrait affecter la fonctionnalité de l'onduleur.

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.

Specifications

About This Appendix

This appendix presents the mechanical specifications for the SolarEdge power optimizers.

Use 5/16” screws and washers to secure the power optimizer units to the racking.

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.

Avant d'installer directement sur le module ou sur le cadre du module, consultez d'abord le fabricant pour information sur la meilleure manière de la positionner et son impact sur la garantie du module.

Mark all mounting hole locations.

Each power optimizer must be attached to the rack using both mounting holes.

Drill the holes.

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.

Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation. Les vibrations qui en résulteraient peuvent endommager la optimiseur de puissance.
