The PV array current is too high

What does 3803 mean?

The current from the PV array has exceeded its maximum permissible level. This can indicate an over-dimensioned array or a fault condition leading to excessive current. This will cause the inverter to shut down for 1 minute and reset automatically on day change.

• Excessive DC input current from the PV array.
• Incorrect module wiring or system design leading to overcurrent.

Click steps to track your progress.

1. 1

   Check the DC input current of the PV array.

2. 2

   Review the module wiring and system design to ensure current limits are not exceeded.

3. 3

   Verify that the PV array's maximum power point voltage (Vmp) and short-circuit current (Isc) are within the inverter's specifications.
