P400 Installation

l Vdc [V]:TheDCinputvoltageofthelongeststringconnectedtotheinverter.There
shouldbeasafetyvoltageof1Vforeachpoweroptimizerinthestring.
NOTE
A measurement error on the inverter LCD of ±3 V is acceptable.
l Pac [w]:theACoutputpower(shouldbe0.0sincetheinverterisOFF).
l OFF:theinverterON/OFFswitchisintheOFFposition.
Step 2: Pairing Power Optimizers to the Inverter
Onceallconnectionsaremade,allthepoweroptimizersmustbelogicallypairedtotheir
inverter.Thepoweroptimizersdonotstartproducingpoweruntiltheyarepairedwithan
inverter.Thisstepdescribeshowtoassigneachinvertertothepoweroptimizersfromwhich
itwillproducepower.
Performthisstepwhenthemodulesareexposedtosunlight.Ifthestringlengthischangedor
apoweroptimizerisreplaced,repeatthepairingprocess.
1. PressandholddowntheinverterLCDLightbuttonforabout10 seconds.Thefollowing
messageisdisplayed:

Keepholdingfor5secondsuntilthefollowingisdisplayed:

2. TurntheinverterON/OFFswitchtoONwithin5seconds.Ifyouwaitlongerthan5
secondstheinverterexitsthepairingmode.Thefollowingmessageisdisplayedindicating
thattheinverterisperformingthepairing:
