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.
IMPORTANTSAFETYFEATURE
Rapid shutdown is applicable and functions only when there are 30 optimizers or less per string.
