{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational with stable voltage quality, though frequent overload events suggest heavy compressor cycling or potential maintenance requirements.\n\n**2. Key Metrics Summary**\n*   **Current Consumption:** 538.8W at 232.5V.\n*   **Average Load:** 565.02W (Range: 1.6W \u2013 2562.4W).\n*   **Total Energy Consumed:** ~246.89 kWh.\n*   **Cost Estimate:** ~27,158 PKR (based on 110 PKR\/kWh).\n*   **Power Factor:** 0.7 (avg), indicating moderate inductive load efficiency.\n*   **Voltage Quality:** 100% EN50160 compliance with zero sags or swells.\n\n**3. Notable Observations**\n*   **Overload Frequency:** The system recorded **639 \"OVERLOAD\" events** over the 21-day period. This is significant and may indicate the refrigerator is struggling to maintain temperatures, possibly due to frequent door openings, excessive ambient heat, or a failing compressor\/refrigerant leak.\n*   **Efficiency:** The Power Factor (avg 0.7155) is relatively low; while standard for refrigeration, it may indicate aging motor components.\n*   **Reliability:** Voltage stability is excellent, ruling out grid-side power quality as a cause for the recorded overloads. Recommendation: Inspect the compressor and door seals to mitigate the high frequency of overload states.","cached_at":"2026-07-29T17:56:44+05:00","expires_at":1785330104}
