Low insulation resistance

¿Qué significa 2062 ?

A short circuit exists between the PV array and the ground, or the PV array is in a moist environment with poor insulation. This is a critical safety fault indicating potential electrical leakage.

• A short circuit exists between the PV array and the ground.
• The PV array is in a moist environment and the circuit is not well insulated to the ground.

1. 1

   Check the impedance between the PV array output and the ground. If a short circuit occurs or the insulation is insufficient, rectify the fault.

2. 2

   Check whether the PE cable of the SUN2000 is correctly connected.

3. 3

   If the impedance is confirmed to be lower than the specified protection threshold in a cloudy or rainy environment, log in to the app, SmartLogger, or NMS and set the Insulation resistance protection threshold.
