| Component | Description | Typical Repair Difficulty | | :--- | :--- | :--- | | | General failure of the power supply system due to overcurrent or poor connection. | Medium to High | | Inverter Circuit | Failure of the power devices (e.g., MOSFETs, IGBTs) in the inverter circuit. | High | | Internal Fuses (Blown) | Blown primary and/or secondary board fuses (e.g., F1201, F1202, F2601, F2602). | Low to Medium | | Relay Failure | Failure of the battery-to-line switching relay (e.g., stuck in a closed position). | Medium to High | | DC Bus Not Charging | DC bus fails to charge to the battery voltage level. The soft-start circuit may be compromised. | Medium to High | | Corrupted Internal Firmware | The UPS's internal microcontroller (MCU) may have corrupted firmware, requiring a reflash. | Low (if reflash works) | | Latched EEPROM Alarm | The alarm code is latched in the EEPROM, requiring special tools or service center intervention to clear. | High (RMA required) |
