نظام طاقة شمسية بقدرة 50 كيلوواط وسعة 150 كيلوواط/ساعة لأحد البنوك | ليبيريا

This 50kW 150kWh solar system powers a commercial bank branch in Liberia, providing reliable backup for critical banking operations including ATM networks, server rooms, and transaction processing systems. The facility consumes approximately 6,000-7,000 kWh monthly and requires zero downtime to protect customer data and maintain regulatory compliance.

Although the bank operates diesel generators as primary backup, prolonged holiday outages have caused repeated disruptions — when diesel fuel runs low during long holiday weekends, server shutdowns result in transaction failures, ATM outages, and potential data loss. The 150kWh battery capacity is specifically sized to maintain critical loads (servers, ATMs, networking equipment, lighting) for up to 3 days without grid or diesel support, fully covering extended holiday periods.

The integrated hybrid system combines grid-tie solar generation with battery backup and automatic transfer switching. During normal operation, the 50kW solar array reduces grid consumption. When grid fails, the system instantly switches to battery mode within 10 milliseconds, then seamlessly integrates diesel when needed. The 150kWh lithium BESS provides 3 days of autonomous operation for the 20kW average critical load — covering even the longest holiday weekends without fuel concerns.

Mars Solar dispatched 1 senior engineer for 7-day on-site commissioning. The team integrated the system with the bank's existing UPS infrastructure, configured priority load shedding for non-critical circuits, and set up encrypted remote monitoring for the IT manager. The bank achieved full ROI within 13 months while eliminating server downtime risks. The system includes iOS/Android apps for real-time monitoring, automatic monthly reports via WhatsApp and email, and 10-year warranty coverage.
