1What the error means
The following error codes of REFUsol inverters belong to the same fault family: over-temperature. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- Dirty or blocked heat sinks and fans
- Installation in an enclosed space without ventilation or in direct sun
- Faulty fan or temperature sensor
3What to do
- Clean the heat sinks and check that the fans are turning.
- Ensure ventilation and shade at the installation site.
- If the fault appears with the unit cold, the sensor or the fan needs to be replaced.

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.
