Appendix D: Inverter Arc Detection and
Interruption
Anelectricarcisanongoinghigh-energydischarge,resultingfromacurrentthroughanormallynon-
conductivematerialsuchasair.
WhenconnectersorcablesinaPVsystemareimproperlyconnectedoraredamaged,theelectric
currentmaypassthroughtheair,causinganelectricarc.Arcsgenerateheatwhichcancausefiresand
theyalsoposeanelectrocutionrisktothoseworkingnearthem.
SolarEdgeinverterscandetectarcsandinterruptproduction.Aqualifiedpersonmustre-enablethe
inverterafterproperlycheckingtheinstallation.
Thearcdetectionoptionisdisabledbydefault.ItmustbeenabledwhenUL1699Bcomplianceisrequired.
To enable/disable arc detection:
1. EnterSetupmodeandscrolltotheMaintenancemenu.
2. SelectAFCI èEnableorDisable.
To manually test the arc detection functionality:
1. MakesuretheinverterON/OFFswitchisturnedON.
2.
UsetheLCDlightbuttontoselectMaintenance èManual AFCI Test.

Ifthetestissuccessful,thefollowingmessageisdisplayed:
M a n u a l T e s t P A S S
Theinverterproductionistheninterrupted(asifarealarcdetectionhasoccurred),and
thefollowingerrormessageisdisplayed(numberedeither150or151):

Performmanualrestarttoresumesystemoperation:TurntheinverterON/OFFswitchto
OFFandthentoON.Theinverterperformsanarcdetectionself-testandstartsnormal
operation.
