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Designerfor
stringlengthverification.
IMPORTANT SAFETY FEATURE
ForacompliantPVRapidShutdownSystem(PVRSS)installation,usenomorethan30
optimizers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.
2.
Connecttherestofthepoweroptimizersinthestringinthesamemanner.
WARNING!
If using a dual-input power optimizer and some inputs are not used, seal the unused input
connectors with the supplied pair of seals.
AVERTISSEMENT!
Si un optimiseur à double entrées est utilisé et que certaines entrées ne sont pas connectées,
fermez ces entrées avec la paire de couvercles fournie.
