1. Check the output-to-ground impedance of the PV array. If a short circuit or inadequate insulation is detected, rectify it.
2. If auto recovery from string-to-ground short-circuit protection is disabled, check and rectify the preceding faults, and manually clear the alarm.
3. If auto recovery from string-to-ground short-circuit protection is enabled, the alarm will be automatically cleared after fault recovery.
