Chapter 2: Installing the Power Optimizers

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. Le perçage de trous dans le cadre du module
devra se faire suivant les instructions du fabricant.
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modules’connectorstowhichtheyareconnected:
lUseidenticalconnectorsfromthesamemanufacturerandofthesametypeonboththepower
optimizersandonthemodules;or
lVerifythattheconnectorsarecompatibleinthefollowingway:
oThemoduleconnectormanufacturershouldexplicitlyverifycompatibilitywiththeSolarEdge
optimizerconnector;and
oA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.
ATTENTION!
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:.
lUtiliser des connecteurs identiques du même fabricant et du même type aussi bien pour les
optimiseurs de puissance que pour les modules.
lVérifiez que les connecteurs sont compatibles de la manière suivante:
oLe fabricant du connecteur doit explicitement vérifier la compatibilité avec le connecteur
SolarEdge.
oUn 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.
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.
