Chapter 1: Introducing the SolarEdge Power Harvesting System
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.
SolarEdge Power Optimizer
The SolarEdge 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:
l
During fault conditions
l
The power optimizers are disconnected from the inverter
l
The inverter’s ON/OFF switch is turned OFF
l
The Safety Switch is turned OFF
l
Inverter's 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:
l
Module Add-on power optimizer – connected to one or more modules
l
Smart modules - the power optimizers are embedded into a module
SolarEdge Inverter
The SolarEdge 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 SolarEdge monitoring portal; requires Internet connection).
SolarEdge Monitoring Portal
The SolarEdge monitoring portal 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.

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. 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.
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 arrêt 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.
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
l
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 16. Also refer to the documentation supplied
with the smart modules.
l
The minimum and maximum string length guidelines are stated in the power optimizer datasheets.
l
If connecting more modules than optimizer inputs in parallel , use a branch cable (available from
SolarEdge).
l
Make sure to use optimizers that have the required output cable length. You can use extension cables between rows and from the end of string to the inverter. Extension cables cannot be used between two power optimizers within a string.
l
The power optimizer can be placed in any orientation.
l
Position the power optimizer close enough to its module so that their cables can be connected.
l
To allow for heat dissipation, maintain a 2.5 cm/ 1" clearance distance between the power optimizer and other surfaces.
l
Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is available on the SolarEdge website at http://www.solaredge.us/groups/support/downloads , under
Software Tools.
l
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 optimizers are connected to unshaded modules, add more optimizers to the string.
l
Do not leave the power optimizers connectors disconnected. Open connectors should be mated to each other.

Step 1: Mounting and Grounding the Power Optimizers
NOTE
The images contained in the following sections are for illustrative purposes only and may vary depending on product models.
Step 1: Mounting and Grounding 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 (See Figure 3). For frame-mounted power
optimizers follow the instructions supplied with the optimizers.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling vibrations 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.
3. Attach each power optimizer to the rack using the M6 (1/4'') stainless steel bolts, nuts and washers.
Apply torque of 9.5 N*m / 7 lb*ft. For 3NA series power optimizes, SolarEdge recommends mounting the power optimizer on a rail with the smooth side facing out, so that the power optimizer body will prevent its rotation.
4. Use the following methods to ground the power optimizer
2
:
WARNING!
The metallic enclosure of the power optimizer must be grounded in accordance with the requirements of the local and national codes.
l
L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en accord avec les régulations locales et nationales.

Figure 6: Power optimizer connectors
Step 3: Connecting Power Optimizers in Strings
You can construct parallel strings of unequal length, that is, the number of power optimizers in each string does not have to be the same. The minimum and maximum string lengths are specified in the power optimizer datasheets. Refer to the SolarEdge Site Designer for string length verification.
NOTE
The total cable length of the string (excluding power optimizers’ cables) should not exceed
1000ft./300m from DC+ to DC- of the inverter.
Use at least 11 AWG/ 4 mm² DC cables.
IMPORTANT SAFETY FEATURE
Rapid shutdown is applicable and functions only when there are 30 optimizers or less per string.
1. Connect the Minus (-) output connector of the string’s first power optimizer to the Plus (+) output connector of the string’s second power optimizer.

Chapter 2: Installing the Power Optimizers
2. Connect the rest of the power optimizers in the string in the same manner.
Figure 7: Power optimizers connected in series
3. If you intend to monitor the installation, using the SolarEdge monitoring portal, record the physical
location of each power optimizer, as described in Providing Installation Information on page 31.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to each other or plugged with appropriate watertight caps.
Les connecteurs d’entrée et sortie ne sont pas étanches jusqu'à ce qu’ils soient accouplés. Les connecteurs doivent être accouplés ou fermés avec des terminaux étanches.
Step 4: Verifying Proper Power Optimizer
Connection
After a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V.
Therefore, the total string voltage should be equal to 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 modules are exposed to sunlight during this process; otherwise, the power optimizers may not be powered. If you use a tracker, the power optimizer will turn ON only if the tracker is tracking the sun and the module provides at least 2W.
In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I those in traditional systems.

Step 2: Pairing Power Optimizers to the Inverter
Step 2: Pairing Power Optimizers to the Inverter
Once all connections are made, all the power optimizers must be logically paired to their inverter. The power optimizers do not start producing power until they are paired with an inverter . This step describes how to assign each inverter to the power optimizers from which it will produce power.
Perform this step when the modules are exposed to sunlight. If the string length is changed or a power optimizer is replaced, repeat the pairing process.
1. Perform pairing: Press and hold down the inverter LCD OK button (rightmost on the communication
board; see Figure 18) for about 10 seconds. The following message 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 . . .
Keep holding for 5 seconds until the following is displayed:
P a i r i n g
T u r n S w i t c h T o O n
2. Turn the inverter ON/OFF switch to ON within 5 seconds. If you wait longer than 5 seconds the inverter exits the pairing mode. The following message is displayed indicating that the inverter is performing the pairing:
P a i r i n g
R e m a i n i n g [ s e c ] : 1 8 0
3. Wait for the completion of the pairing (remaining seconds is 0). If pairing fails, an error is displayed. In
this case, repeat the pairing steps, and refer to Power Optimizer Troubleshooting on page 62. If the
problem persists, contact SolarEdge Support. When pairing 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
4. Upon pairing completion, the inverter continues with assigning numbers to the power optimizers and mapping them into strings:
l
Power optimizer detection - the power optimizer IDs are detected and each optimizer is assigned a unique number, which is later used by the inverter for synchronizing telemetries. This detection is performed while the optimizers are in safe voltage .
l
String detection - During this procedure the logical string of each optimizer is detected. This detection is performed while some optimizers are set to MaxVout mode.
The detection and assignment of power optimizers may take up to 2 minutes.
The system startup process begins:
Since the inverter is ON, the power optimizers start producing power and the inverter starts converting
AC.

Chapter 7: Setting Up Communication
Chapter 7: Setting Up Communication
Power optimizers send information to the inverter via the DC power lines (the PV output circuit). The information is sent from the inverter to the SolarEdge monitoring portal through the Internet. In order to send the data from the inverter, a communication connection must be set up, as described in this chapter. Communication setup is not required for power harvesting, however is needed for using the
SolarEdge monitoring portal.
This chapter describes setting up communication between multiple inverters for a master/slave configuration.
CAUTION!
When connecting the communication cables, make sure that the ON/OFF switch at the bottom of the inverter is turned OFF, and the AC is turned OFF.
When configuring the communication parameters, make sure that the ON/OFF switch is OFF, and the AC is turned ON.
Lors de la connexion des câbles de communication, assurez-vous que l'interrupteur
MARCHE/ARRÊT à la base de l'onduleur soit en position ARRÊT, et le CA est en position

Power Optimizer Troubleshooting
Power Optimizer Troubleshooting
If the inverter status screen indicates that not all power optimizers are paired or not all are reporting (P_OK xxx/yyy, and x<y), those optimizers can be identified through the
LCD. Refer to http://www.solaredge.us/files/pdfs/products/inverters/non-respondingpower-optimizers.pdf
Problem Possible cause and troubleshooting
Pairing failed
String voltage is 0V
String voltage not 0V but lower than number of optimizers
Power optimizers are shaded.
If you connected the inverter to the SolarEdge monitoring portal, retry pairing remotely (during sunlight).Make sure to leave the inverter ON/OFF switch ON and that S_OK appears on the LCD..
Power optimizer(s) output is disconnected.
Connect all power optimizer outputs
Power optimizer(s) not connected in the string.
Connect all power optimizers
Module(s) not connected properly to power optimizer inputs (not applicable to smart modules).
Connect the modules to the optimizer inputs
String reverse polarity.
String voltage is higher than the number of optimizers
WARNING!
Check string polarity using a voltmeter and correct if needed.
Extra power optimizer(s) connected in the string (not applicable to smart modules).
If the measured voltage is too high, the installation may not have a safe low voltage.
PROCEED WITH CARE! A deviation of ±1% per string is reasonable.
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.
Si la tension mesuree est trop haute, la tension basse de securite pourrait manquer dans l’installation. REDOUBLEZ DE
PRECAUTION. Une deviation de ±1% par string est raisonnable.
o
Disconnect the wires connecting the power optimizers in the string.
o
Measure the output voltage of each power optimizer to locate the power optimizer that does not output 1V safety voltage. If a malfunctioning power optimizer is located, check its connections, polarity, module, and voltage.
o
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 C: Inverter Arc Detection and Interruption
Appendix C: Inverter Arc Detection and
Interruption
An electric arc is an ongoing high-energy discharge, resulting from a current through a normally nonconductive material such as air.
When connecters or cables in a PV system are improperly connected or are damaged, the electric current may pass through the air, causing an electric arc. Arcs generate heat which can cause fires and they also pose an electrocution risk to those working near them.
SolarEdge inverters can detect arcs and interrupt production. A qualified person must re-enable the inverter after properly checking the installation.
The arc detection option is disabled by default. It must be enabled when UL1699B compliance is required.
To enable/disable arc detection:
1. Enter Setup mode and scroll to the Maintenance menu.
2. Select AFCI è Enable or Disable.
To manually test the arc detection functionality:
1. Make sure the inverter ON/OFF switch is turned ON.
2. Use the LCD light button to select Maintenance è Manual AFCI Test.
l
If the test is successful, the following message is displayed:
M a n u a l T e s t P A S S
The inverter production is then interrupted (as if a real arc detection has occurred), and the following error message is displayed (numbered either 150 or 151):
E r r o r C o d e 1 8 x C
A r c F a u l t D e t e c t e d
Perform manual restart to resume system operation: Turn the inverter ON/OFF switch to
OFF and then to ON. The inverter performs an arc detection self-test and starts normal operation.
l
If the test fails, contact SolarEdge support.
64
SolarEdge HD-Wave Inverter Installation Guide MAN-01-00306-1.0
Appendix C: Inverter Arc Detection and Interruption
To troubleshoot arc-fault failures:
The inverter continuously performs arc detection while producing power. If an electric arc occurred in the PV system, the inverter detects it and stops producing power. The following error message is displayed (numbered either 150 or 151):
E r r o r C o d e 1 8 x C
A r c F a u l t D e t e c t e d
If this message is displayed:
1. Turn the inverter ON/OFF switch to OFF.
2. Check all PV strings for the correct open-circuit voltage:
l
Inspect all connections and cables between the power optimizers in the strings: Verify they are connected properly by firmly pushing the plugs and verifying the connectors are locked.
l
Inspect all connections and cables between the PV modules and the power optimizers: Verify they are connected properly by firmly pushing the plugs and verifying the connectors are locked.
l
Verify that the strings are firmly attached to the Safety Switch terminal blocks.
3. Perform manual restart to resume system operation: Turn the inverter ON/OFF switch to OFF and then ON. The inverter performs an arc detection self-test and starts normal operation.
To troubleshoot self-test failures:
If the self-test fails, the inverter displays an error message indicating that the arc detector hardware failed during wake-up tests:
E r r o r C o d e 1 8 x 8 D
A F C I s e l f - t e s t f a i l e d
The inverter transmits an error message to the monitoring portal, and continuously repeats the arc detection self-test until it is successful.
