GoodWe error 04: DCI consistency failure
GoodWe alarm 04 usually indicates a DCI (Digital Current Injection) consistency failure. This can occur due to temporary external interference such as magnetic fields or, less commonly, a fault in an internal inverter component.
This is a protective response by the inverter to ensure safe operation of the DC circuitry and prevent damage or unsafe operation. Intermittent faults may clear themselves once the external condition is resolved.
Contact e-Solar for professional inverter support
If the alarm occurs, restart the inverter and observe whether the fault reoccurs. If the issue is temporary, no further action may be required.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
If the alarm persists, do not attempt to open or service the inverter yourself. Our Perth-based team can inspect the inverter, check DCI circuits and connections, and determine whether an internal component fault is present.
