Status Code 1083 - Insulation warning

What does 1083 mean?

Status code 1083 is displayed on the inverter's user interface if the measured insulation resistance drops below the set threshold. This indicates a potential insulation fault in the PV system.

• Insulation fault in the PV system
• Insulation resistance below threshold (e.g. 100000 Ω)
• Damage to PV modules or wiring insulation

Click steps to track your progress.

1. 1

   Check the inverter's user interface for the exact insulation resistance value.

2. 2

   Inspect all PV modules and wiring for visible damage to insulation.

3. 3

   If the warning persists, contact a qualified installer or service technician to diagnose the insulation fault.
