GoodWe error code: DCI Injection High
GoodWe DCI Injection High usually indicates that the DC component in the inverter’s AC output exceeds the allowed threshold according to your country’s settings. This can be triggered by unstable DC input, wiring issues, or internal inverter protection behaviour.
When this occurs, the inverter may trigger protection and stop exporting power to the grid until the fault is cleared. Occasional occurrences may be related to temporary conditions, but persistent alarms suggest a problem that requires professional assessment.
Contact e-Solar for safe DCI inspection
Power off the inverter before inspection (turn off the AC output and DC input switches) and follow the safety label instructions. After powering on, e-Solar can inspect the DC input, verify AC output, and confirm that the DC component is within acceptable limits.
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
Do not attempt to open the inverter or test AC/DC circuits yourself. High-voltage DC conditions can be dangerous. If the alarm continues, our technicians can safely assess the inverter and resolve the issue.
