{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe system is operating stably within voltage compliance, though the high frequency of overload events suggests potential mechanical strain or startup inefficiencies.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 538.5W (0.7 PF) at 235.4V.\n*   **Aggregate Power:** Avg 563.29W (Range: 1.6W \u2013 2,562.4W).\n*   **Efficiency\/Quality:** 100% EN50160 voltage compliance (no sags\/swells).\n*   **Total Energy Consumed:** ~143.13 kWh over 12 days.\n*   **Operational Health:** 97.1% Active time vs. 2.8% Overload time.\n\n**3. Notable Observations**\n*   **Overload Frequency:** With 328 \"OVERLOAD\" readings recorded, the unit is frequently spiking well above its average load. While the 2,562W peak is likely a compressor startup surge, the high count of overload events warrants a check of the compressor\u2019s start relay or thermal protection.\n*   **Power Factor:** The average PF of 0.71 is relatively low, indicating reactive power losses. This may lead to unnecessary utility surcharges or inefficient energy utilization.\n*   **Stability:** Voltage regulation is excellent (avg 234.77V), suggesting the restaurant\u2019s electrical supply is clean and stable.","cached_at":"2026-07-20T14:44:47+05:00","expires_at":1784540987}
