1What the error means
The following error codes of REFUsol inverters belong to the same fault family: grid over-voltage. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- High grid voltage at the point of connection
- Undersized or very long AC cable — the inverter raises the voltage while it feeds in
- Several inverters on the same line
- Wrong country setting
3What to do
- Measure the voltage at the point of connection while the inverter is feeding in.
- Check the cross-section and length of the AC cable.
- If the grid voltage is permanently high, notify the grid operator.
- If the voltage is normal and the fault persists, the inverter's measuring circuit needs to be checked.

| 0x090019 | Grid over-voltage — the power stage detected a phase over-voltage |
| 0x090054 | The phase voltage exceeded the average voltage limit for too long |
| 0x090055 | Grid over-voltage — phase over-voltage (AC) detected |
| 0x0A000D | Grid over-voltage — phase over-voltage (AC) detected |
| 0x0A000F | Grid over-voltage between phases (line-to-line voltage) |
| 0x0A0018 | The average grid voltage stayed above the limit for too long |
| 0x0A0025 | Power reduction due to high grid voltage, P(V) |
| 0x0A0026 | Power reduction due to high grid voltage, P(V) |
| 0x0A0109 | Grid over-voltage — the power stage detected a phase over-voltage |
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.
