- Error code
- E058
- Category
- Internal inverter fault
- Manufacturer
- ABB / FIMER
1What the error means
Code E058 (Pin vs Pout check error) appears when the difference between the measured input power (DC) and output power (AC) exceeds the limit set internally by the manufacturer. This is an internal check of the device and cannot be corrected externally. It usually occurs at high power output, and the exact cause is identified through diagnosis in the workshop.
2Possible causes
- Fault in the inverter's voltage or current measuring circuit
- Measurement mismatch between the internal boards
- Fault on the control board or power board
- Wear of components in the power conversion stage
3What to do
- Switch off the inverter on both the AC and DC side, wait a few minutes and switch it back on.
- Note whether the fault appears only at high power output, for example around midday, to help with diagnosis.
- If the fault persists after the restart, the inverter needs to be checked in the workshop.
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.
