8 Diagnostics and data evaluation
8.1 Malfunction rectication
Thesolarinverterisprovidedwithanautomaticdiagnosticssystemwhichindependentlyidenties
certainfaultsandwhichcanmakethemvisibleonthedisplay.
Troubleshooting in the eld
Inprinciple,itisalwaysworthattemptingaresetbyreinitializingthesolarinverterwheneveranerror
messageappearsonthedisplay.
To reset the device, proceed as follows:
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
aboutpotentialfaultcauses.
