certainfaultsandwhichcanmakethemvisibleonthedisplay.

1.Isolatethesolarinverterfromthegrid(openautomaticcircuitbreaker).
2.SwitchofftheDCdisconnector.
3.Wait:approx.1minute.
4.SwitchDCdisconnectorbackon.
5.Switchingrid(closeautomaticcircuitbreaker).
(Intheeld,therststepistoscanforpotentialfaultcausesthatcouldbepickedupbythesolar
inverterandresultintripping.)
Variouskeyparameterscanbescannedviathedisplay,therebyenablingconclusionstobedrawn
