SolarEdge SE66.6KUS - Step 1: Mounting and Grounding the Power Optimizers


o
Donotuseextensioncablesbetweenamoduleandapoweroptimiser,betweentwomodules
connectedtothesameoptimiser,orbetweentwooptimisersotherthaninthecasesspecified
below.

o
Youcanuseextensioncablesbetweenpoweroptimisersonlyfromrowtorow,aroundobstacles
withinarow,andfromtheendofthestringtotheinverter,aslongasthemaximumdistanceis
notexceeded.
l Theminimumandmaximumstringlengthguidelinesarestatedinthepoweroptimiserdatasheets.
RefertotheDesignerforstringlengthverification.TheDesignerisavailableontheSolarEdgewebsite
athttps://www.solaredge.com/us/products/installer-tools/designer#/.
l Completelyshadedmodulesmaycausetheirpoweroptimiserstotemporarilyshutdown.Thiswill
notaffecttheperformanceoftheotherpoweroptimisersinthestring,aslongastheminimum
numberofunshadedpoweroptimisersconnectedinastringofmodulesismet.Ifundertypical
conditionsfewerthantheminimumoptimisersareconnectedtounshadedmodules,addmore
optimiserstothestring.

l Toallowforheatdissipation,maintaina2.5cm/1"clearancedistancebetweenthepoweroptimiser
andothersurfaces,onallsidesexceptthemountingbracketside.

(BIPV)modules,ventilationmeasuresmaybeneededtoensurethepoweroptimisersarenotbe
exposedtotemperaturesoutsidetheirspecifications.
