SolarEdge storedge - Pairing Power Optimizers to the Inverter

11. ClosetheStorEdgeConnectionUnitexternalcover:Attachthecoverandsecureitbytighteningthe
sixscrewswithatorqueof1.2N*m/0.9ft.*lb.
12. Ensureproperconduitsealing;inspecttheentireconduitrunandusestandardconduitsealantsto
avoidwaterpenetration.
13.
TurnONtheStorEdgeConnectionUnitswitch.IfanadditionalexternalDCswitchisinstalledbetween
thepoweroptimizers/batteryandtheinverter(s)thenturnitON.
AstatusscreensimilartothefollowingappearsontheLCDpanel:
V a c [ V ] V d c [ V ] P a c [ w ]
2 4 0 . 7 1 4 . 1 0 . 0
P _ O K : 0 0 0 / 0 0 0 < S _ O K >
- - - - - - - - - - - - - - - O F F
14. VerifythatthefollowinginformationappearsontheLCDpanel:
l P_OK:Appearsonlyuponpairingprocesscompletionandfirsttelemetryreceptionfromthe
poweroptimizers.Indicatesconnectiontothepoweroptimizersandthatatleastonepower
optimizerissendingmonitoringdata.IfP_OKdoesnotappear,checkthepoweroptimizer,string
andDCinputconnections.
l 000/000:Appearsonlyuponfirsttelemetryreceptionfromthepoweroptimizers.Indicatesthe
numberofpoweroptimizersthathavebeenpairedtothisinverter.Atthisstage,thenumber
shouldbe000,sincenopoweroptimizershavebeenpaired.
l S_OK:theconnectiontotheSolarEdgemonitoringplatformissuccessful(shouldappearonlyif
theinverterisconnectedtotheserver).IfS_OKisnotdisplayedandtheinverterisconnectedto
theserver,refertoTroubleshootingonpage87.
l Vac [V]:thegridACoutputvoltage.Verifythecorrectvalue.
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.
Performpairing:PressandholddowntheinverterLCDbuttonforabout10 seconds.Thefollowing
messageisdisplayed:
