Installation Guidelines
l Frame-mountedpoweroptimizersaremounteddirectlyonthemoduleframein
rail-lessrackingsystems.Mountingthepoweroptimizersinadvancesavesinstallation
time.Forinstallationofframe-mountedpoweroptimizers,referto
http://www.solaredge.com/sites/default/files/installing_frame_mounted_power_
optimizers.pdf.
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18.Alsorefertothedocumentationsupplied
withthesmartmodules.
l Thepoweroptimizercanbeplacedinanyorientation.
l Toallowforheatdissipation,maintaina24.5mm/1"clearancedistancebetweenthepower
optimizerandothersurfaces.
l Ifconnectingmoremodulesthanoptimizerinputsinparallel,useabranchcable(availablefrom
SolarEdge).
l Positionthepoweroptimizercloseenoughtoitsmodulesothattheircablescanbeconnected.
l Makesuretouseoptimizersthathavetherequiredoutputcablelength.Youcannotuseextension
cablesbetweeneverytwooptimizersinastring;Theymaybeusedonlytoconnectbetweenrows/
arraysorbetweenthestringandtheinverter.
l Theminimumandmaximumstringlengthguidelinesarestatedinthepoweroptimizerdatasheets.
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/products/installer-tools/site-
designer#/.
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 Equipmentgroundingtighteningtorques:4-6AWG:45lb-in,8AWG:40lb-in,10-14AWG:35lb-in.
