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15.Alsorefertothedocumentationsupplied
withthesmartmodules.
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 Theminimumandmaximumstringlengthguidelinesarestatedinthepoweroptimizerdatasheets.
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.
l Equipmentgroundingtighteningtorques:4-6AWG:45lb-in,8AWG:40lb-in,10-14AWG:35lb-in.

:
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2).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.
