{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational and stable, maintaining high voltage compliance, though experiencing frequent overload events.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 563.2W (Avg: 583.95W)\n*   **Efficiency:** Power Factor (PF) is low at 0.71 (Avg: 0.72).\n*   **Consumption:** 69.57 kWh total energy recorded over 5 days.\n*   **Voltage:** Stable at 235V (100% EN50160 compliance).\n*   **Operating Cost:** Total consumption at 110 PKR\/kWh equates to ~7,653 PKR for the observed period.\n\n**3. Notable Observations**\n*   **Overload Frequency:** The device recorded 280 \"OVERLOAD\" instances against 3,826 active readings. This suggests the refrigerator is frequently exceeding its nominal capacity, likely during compressor startup cycles or heavy cooling demands.\n*   **Low Power Factor:** A PF of 0.71 indicates poor electrical efficiency, suggesting potential motor wear or an aging capacitor.\n*   **Stability:** Despite the load spikes, voltage regulation is excellent (217.8V\u2013244.2V), with no sags or swells detected, indicating a high-quality power supply.\n\n**Recommendation:** Investigate the compressor and cooling system to address the persistent overload state and consider power factor correction to reduce reactive power losses.","cached_at":"2026-07-14T00:03:33+05:00","expires_at":1783969713}
