A diagnostic system for a UPS module has a battery diagnostics module, an inverter diagnostic module, a utility diagnostic module, and a transformer diagnostic module. The battery diagnostic module is configured to generate battery diagnostic information based on at least one operating characteristic of at least one element of the battery module. The inverter diagnostic module is configured to generate inverter diagnostic information based on at least one operating characteristic of at least one element of the inverter module. The utility diagnostic module is configured to generate utility diagnostic information based on at least one operating characteristic of at least one element of the utility power signal supplied by the utility power supply. The transformer diagnostic module is configured to generate transformer diagnostic information based on at least one operating characteristic of at least one element of the transformer module.
