Low Insulation Resistance

Was bedeutet 2062 ?

PV arrays are short-circuited with PE, or the ambient air around the PV array is damp, leading to poor insulation between the PV array and the ground. This presents a safety risk and can hinder inverter operation.

• PV arrays are short-circuited with PE.
• The ambient air of the PV array is damp and the insulation between the PV array and the ground is poor.

1. 1

   Check the output resistance of the PV array to ground. If there is a short circuit or lack of insulation, rectify it.

2. 2

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

3. 3

   If you are sure that the impedance is less than the default value in a cloudy or rainy environment, log in to the mobile phone app, SmartLogger, or NMS and reset the insulation impedance protection threshold.
