The short answer
It auto-resets, but if string Voc is critical the installer must re-organise the panels.
Plain explanation
From the Victron manual for the SmartSolar MPPT: Auto-resets. Voc config critical → re-organise panels (installer). Installer only: DC and AC work on a live PV system is dangerous, so owners should note the code and call their installer.
