- Error code
- 6801
- Category
- Input A defective
- Manufacturer
- SMA
- Models
- Sunny Tripower (STP)
1What the error means
Self-diagnosis: the inverter detected a problem on DC input A, i.e. the first MPP tracker. The cause may be the string connected there or the input circuit itself.
2Possible causes
- Fault in the string on input A — voltage, polarity or short circuit
- Fault in the inverter's MPP tracker A
3What to do
- Measure the voltage and polarity of the string on input A.
- Try the same string on input B: if the fault moves, the PV generator is at fault; if it stays on A, the inverter is at fault.
Same code group
Code 6801 belongs to the same group as 6802 — they share the same cause and the same remedy.
