1What the error means
The following error codes of REFUsol inverters belong to the same fault family: internal error. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- Fault on the power or control board
- Worn capacitors
- Damage from overvoltage — lightning or grid
3What to do
- Switch off AC and DC, wait 2–3 minutes and restart once.
- If the code returns, it cannot be fixed on site — it needs diagnosis 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.
