- Manufacturer
- REFUsol
1What the error means
The following error codes of REFUsol inverters belong to the same fault family: over-current. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- Sudden change or short circuit on the grid
- Fault in the power bridge
3What to do
- Check the AC connection and the grid.
- If it returns with no external cause, the power stage needs to be checked in our lab.

4Repair by Aineas
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.
