Insulation Fault Warning

What does 1083 mean?

Status code 1083 is displayed when the measured insulation resistance drops below a predefined threshold, indicating a potential insulation fault in the system. This warning is output when the 'Insulation warning' parameter is activated. The system's 'Insulation measurement mode' determines the accuracy and display of this value.

• Insulation resistance dropping below the set 'Threshold for the insulation warning'.
• An insulation fault within the PV system or associated wiring.

Click steps to track your progress.

1. 1

   Verify the 'Insulation warning' parameter is set to 'On' to enable insulation monitoring.

2. 2

   Check the 'Threshold for the insulation warning' parameter value (100000 - 10000000 Ω) and adjust if appropriate for the installation.

3. 3

   If 'Insulation measurement mode' is set to 'Fast', change it to 'Exact' to display the measured insulation resistance on the user interface and get a more accurate reading.

4. 4

   Perform an insulation resistance test on the PV array and wiring to identify the specific location of the fault.
