What to do if my SMA SUNNY MINI CENTRAL 9000TL displays 'Vac-Bfr Vac-Srr'?

If your SMA Inverter displays 'Vac-Bfr Vac-Srr', it means that the mains voltage is no longer within the permissible range. Make sure that the AC cable is correctly connected and that the mains voltage is in the permissible range.
