{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe system is operating within acceptable parameters, consuming 415.83 kWh to date with a stable average load of 550.14W.\n\n**2. Key Metrics Summary**\n*   **Power:** Current draw is 557.4W (avg: 550.14W; peak: 2562.4W).\n*   **Efficiency:** Power Factor (PF) is low at 0.72, indicating suboptimal electrical efficiency.\n*   **Voltage:** Stable at 232.3V (avg: 229.04V); 98.33% compliance with EN50160 standards.\n*   **Cost Estimate:** Total consumption cost is approximately 45,741 PKR (at 110 PKR\/kWh).\n\n**3. Notable Observations**\n*   **Overload Incidents:** The system recorded 996 \"OVERLOAD\" states. Given the peak power of 2562.4W, these spikes suggest high inrush currents during compressor startup or potential electrical stress.\n*   **Power Factor:** A PF of 0.72 is relatively low for commercial refrigeration. Improving this through capacitor bank maintenance or motor diagnostics could reduce line losses.\n*   **Voltage Quality:** While compliance is high, the 585 recorded sags suggest localized grid instability, though no swells were detected.\n*   **Operational Uptime:** The unit remains highly active, with 33,503 active readings versus only 623 \"OFF\" states, indicating near-continuous operation.","cached_at":"2026-08-14T10:43:31+05:00","expires_at":1786686511}
