Error Code - 6425 - Synchronization Error


Error No.ExplanationCorrective measures
6425Synchronization error with the utility grid• Contact Solar Support

When the inverter is having difficulty synchronizing, it is typically caused by loose connection at the X55, X56, or X57 connections on the SC20Cont. Try monitoring the Vac, VacInv, VacL1,L2, L3 and the BfrVacL1,L2,L3 spot values to see if there's a change when you're moving the conductors

Often, the ferrules will wiggle loose, so be sure to push the small conductors into the connector to get a good connection. This can get the inverter back up and running for temporary relief, but you may want to replace the cable if you've discovered a problem.
