1What the error means
The following error codes of REFUsol inverters belong to the same fault family: DC link. Find the code shown by your inverter in the table and see what it means.
2Possible causes
- Worn or dried-out DC link capacitors
- Fault in the boost converter circuit
- Sudden voltage changes
3What to do
- One restart with AC and DC switched off.
- If it returns, the DC link capacitors need to be checked and usually replaced.
