1What the error means
Excessive DC current at the output (DC Injection Over-current): the inverter is feeding more DC current into the grid than the standard allows.
2Possible causes
- Fault in the power bridge
- Fault in the current measuring circuit
3What to do
- Restart once.
- If it returns, repair is required — the standard does not allow operation with DC current fed into the grid.

You send the inverter to our lab in Thessaloniki. We diagnose it, inform you of the fault and the cost, and the repair starts only after you approve it. Every inverter is tested under simulated operating conditions before delivery.
