10043 Internal Fault IDSP DCV CNTL Inverter DC Voltage Control fault System Severity Level 4 Symptom Probable Cause Analysis Repair Solution In Grid Connected DC voltage control mode, the real current reference has reached the inverter out- put current limit for more than the DC voltage con- trol timeout period. The DC voltage con- trol timeout period is wrongly set. Make sure that the power board PM is programmed properly, and it is supported by the installed control software. Re-program the power board PM. Open/Loose Con- nection Check the connection of the cable that connects the port J15 of the DPC control board. Tighten cable con- nections Debris or water in package Inspect the DPC power board, control board and the cables connecting them for any mate- rial that could short connec- tions. Clean DPC Faulty DPC Control Board DPC Control Board needs replacing. Replace DPC Con- trol Board Faulty DPC Power Board DPC Power Board needs replacing. Replace DPC Power Board 10044 Internal Fault IDSP ACT ISL Inverter Active Island Detection System Severity Level 4 Symptom Probable Cause Analysis Repair Solution If active anti-islanding is enabled and a ROCOF fault is detected. The grid is in fault condition. Espe- cially, a local island has formed Check the quality of the grid and make sure that no local island has formed. Clear the fault condition of the grid. The grid 3-phase voltages are dis- torted too much. Check the harmonic injection to the grid by the near-by elec- tronic and other high power equipment. Improve the quality of the grid voltage waveform. Some or all of the PM parameters used to detect this fault are set wrongly. Make sure that the power board PM is programmed properly, and it is supported by the installed control software. Re-program the power board PM.
