{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operating within normal parameters with 100% voltage compliance, though efficiency is impacted by a low power factor.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 607.9W (at 236.6V).\n*   **Historical Average:** 564.62W consumption over 13 days.\n*   **Total Energy Consumed:** ~160.16 kWh (~17,618 PKR cost).\n*   **Voltage Quality:** Excellent; 100% EN50160 compliance with no sags or swells.\n*   **Power Factor (PF):** Average 0.71 (range 0.66\u20131.0).\n\n**3. Notable Observations**\n*   **Efficiency:** The low average Power Factor (0.71) indicates significant reactive power losses, which may increase utility surcharges.\n*   **Stability:** The unit experienced 396 \"OVERLOAD\" events despite the average power being well within limits. This suggests high inrush currents during compressor startup rather than sustained electrical faults.\n*   **Operational Uptime:** With only 15 readings recorded as \"OFF\" out of over 12,000, the refrigerator is maintaining near-constant operation, which is expected for commercial kitchen equipment.","cached_at":"2026-07-21T16:02:53+05:00","expires_at":1784632073}
