the AC circuit breaker on the main AC distribution panel.
Avant de faire ces étapes, éteignez l'onduleur monophasé en mettant sur OFF l'interrupteur ON/OFF
situé au bas de l'onduleur.
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.
CAUTION!
Power optimizers are IP65/NEMA4 rated. Choose a mounting location where optimizers will not be
submerged in water.
Les optimiseurs de puissances sont compatibles à la norme IP65/NEMA4. Choisissez le lieu de
montage tel que l’optimiseur ne puisse pas être submergé par l’eau.
CAUTION!
This unit must be operated according to the operating specifications provided with the unit.
Cette unité doit être opérée suivant les instructions trouvées dans le manuel fourni avec le produit.
CAUTION!
Cutting the power optimizer input or output cable connector is prohibited and will void the warranty.
Sectionner les cables d’entrées ou de sortie de l’optimiseur est interdit et annule sa garantie.
CAUTION!
All PV modules must be connected to a power optimizer.
Tous les modules doivent être connectés à un optimiseur de puissance.
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.

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.

Step 2: Connecting a PV Module to a Power
Optimizer
NOTE
Images are for illustration purposes only. Refer to the label on the product to identify the plus and
minus input and output connectors.
Foreachofthepoweroptimizers1:
lConnectthePlus(+)outputconnectorofthemoduletothePlus(+)inputconnectorofthepower
optimizer.
lConnecttheMinus(-)outputconnectorofthemoduletotheMinus(-)inputconnectorofthe
poweroptimizer.
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.

Step 2: Connecting a PV Module to a Power Optimizer

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ISCandtheopencircuitvoltageVOCholddifferentmeaningsfrom
thoseintraditionalsystems.
FormoreinformationabouttheSolarEdgesystem’sstringvoltageandcurrent,refertotheVOC and ISC in
SolarEdge Systems Technical Note,availableontheSolarEdgewebsiteat:
http://www.solaredge.us/files/pdfs/isc_and_voc_in_solaredge_systems_technical_note.pdf.
To verify proper power optimizers connection:
Measurethevoltageofeachstringindividuallybeforeconnectingittotheotherstrings
ortotheinverter.Verifycorrectpolaritybymeasuringthestringpolaritywitha
voltmeter.Useavoltmeterwithatleast0.1Vmeasurementaccuracy.
