Optimizer

NOTE

Imagesareforillustrationpurposesonly.Refertothelabelontheproducttoidentifytheplusand

minusinputandoutputconnectors.

Foreachofthepoweroptimizers:

l ConnectthePlus(+)outputconnectorofthemoduletothePlus(+)inputconnectorofthepower

optimizer.

l ConnecttheMinus(-)outputconnectorofthemoduletotheMinus(-)inputconnectorofthe

poweroptimizer.

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.

NOTE

l Useatleast11AWG/4mm²DCcables.

l Thetotalcablelengthofthestring(excludingpoweroptimizers’cables)shouldnotexceed

1000ft./300mfromDC+toDC-oftheinverter.

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.
