10008 Internal Fault IDSP OV A Inverter Phase A Overvoltage System Severity Level 4 In the Grid Connect mode, the AC overvoltage indicates that the grid is operating under some fault condition or that a local island has formed. In the Stand Alone mode, the AC overvoltage may damage the customer load. In either case, it is important that the inverter be shut down. The software declares an AC overvoltage fault, when any of the magnitude estimates of the phase A, B or C voltage inputs exceeds [(√2) x AC Max Voltage Limit], for a period of time greater than the AC Overvoltage Time-out. 10009 Internal Fault Inverter Phase B Overvoltage System Severity Level 4 10010 Internal Fault IDSP OV B IDSP OV C Inverter Phase C Overvoltage System Severity Level 4 Symptom Probable Cause Analysis Repair Solution Phase A, B or C voltage reading is higher than the AC overvoltage limit. The AC overvolt- age limit is wrongly set. Make sure that the power board Personality Module (PM) is programmed properly, and it is sup- ported by the control software being used. Re-program the frame PM or reset the limits. Open/Loose Connection Check the connection of the cable that connects to the port J15 of the DPC Control Board. Tighten cable connections Phase A, B or C voltage is too high. Inspect the grid voltage. If there is any transformer between the system and the grid, make sure that its wire connections are correct. Solve the problem of the grid. The neutral is not grounded properly. Inspect the grounding wires. In the Grid Connect application, the neutral should not be grounded. However, the neutral must be grounded in the Stand Alone application. Correct the error in grounding. The system failed before it is synchronized to the grid In the Grid Connect mode, if the sys- tem failed before it is synchronized to the grid, all of the following faults will be set: Overvoltage and undervoltage in all three phases. Overfrequency and underfrequency faults. Generally, one or more other faults will also be set, and the extra fault information gives the true reason of the failure. Solve the problems indicated by the other fault codes.
