{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational with stable voltage, though it exhibits significant power inefficiency and frequent overload events.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 520.2W at 232.4V.\n*   **Average Consumption:** 570.08W (Peak: 2562.4W).\n*   **Efficiency:** Average Power Factor (PF) of 0.716 (Low\/Inductive).\n*   **Operational Health:** 100% EN50160 voltage compliance; zero sags\/swells.\n*   **Total Energy Consumed:** ~83.31 kWh over the 7-day period.\n\n**3. Notable Observations**\n*   **Overload Frequency:** With 281 \"OVERLOAD\" readings recorded, the compressor or motor is frequently drawing current significantly above nominal levels. This suggests potential mechanical strain or a failing starter relay.\n*   **Low Power Factor:** A PF of 0.716 indicates poor electrical efficiency, likely causing unnecessary heat and potential utility surcharges.\n*   **Duty Cycle:** The unit is rarely off (only 7 readings), suggesting either a heavy workload or a thermostat\/sensor malfunction preventing the cooling cycle from terminating. \n*   **Recommendation:** Immediate inspection of the compressor and cooling system is advised to address the frequent overloads and improve power factor efficiency.","cached_at":"2026-07-15T18:30:36+05:00","expires_at":1784122536}
