1What the error means
Leakage current sampling fault (Leakage Current Sampling Fault): the inverter cannot trust its residual current measurement, so it is not allowed to operate.
2Possible causes
- Fault in a sensor or measuring circuit
- Discrepancy between the two independent safety measurements
- Damage from overvoltage
3What to do
- One restart with AC and DC switched off.
- If it returns, the measuring circuit needs to be checked in our lab — the inverter is not allowed to operate with an unreliable measurement.
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.
