1What the error means
The following error codes of REFUsol inverters belong to the same fault family: leakage current. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- Ground fault in the PV generator
- Moisture in the installation
- Faulty module or cable
- Fault in the inverter's residual current sensor
3What to do
- Check the PV generator for a ground fault, especially after rain.
- Measure the insulation resistance.
- If the fault also appears with the PV generator disconnected, the fault is in the inverter.
