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SolarEdgeSiteDesignerforstringlengthverification.
NOTE
The total cable length of the string (including power optimizers’ cables) should not exceed
1000ft./300m from DC+ to DC- of the inverter. Use at least 11 AWG/ 4 mm² DC cables.
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.
