Insulation measuring is being performed

Hva betyr 3517 ?

This message indicates that the inverter is currently performing an insulation measurement. This is a normal operational state and not a fault. No corrective action is required.

1. 1

   Verify inverter status display and operational logs to confirm the 'Insulation measuring' message and check for any concurrent fault codes or warnings.

2. 2

   Consult the SMA SUNNY CENTRAL 500CP XT / 630CP XT user manual to determine the typical duration and expected behavior during insulation measurement for this specific model.

3. 3

   Monitor the inverter's operational state to observe if it transitions from 'Insulation measuring' to a normal operational state (e.g., 'Feeding-in' or 'Standby') within the expected timeframe.

4. 4

   Inspect all DC cabling from the PV array to the inverter, including connectors and string fusing, for signs of physical damage, moisture ingress, or loose connections that could affect insulation resistance if the measurement persists or fails to complete.
