Built-in PID operation abnormal

What does 2085 mean?

This Minor alarm indicates an issue with the built-in Potential Induced Degradation (PID) operation. It can be caused by low output resistance of PV arrays to ground or low system insulation resistance, affecting the compensation function.

• The output resistance of PV arrays to ground is low.
• The system insulation resistance is low.

Click steps to track your progress.

1. 1

   Turn off the AC output switch and DC input switch.

2. 2

   Wait for the specified time (as per device safety warning label), then turn on the DC input switch and AC output switch.

3. 3

   Check the impedance between the PV array output and the ground. Rectify any short circuits or insufficient insulation.
