A medium-sized manufacturing factory in northern Nigeria is engaged in the production of building materials. The factory is located in an industrial zone with extremely unstable public power grid coverage, with daily power outages lasting 6-8 hours. Frequent power interruptions lead to production line shutdowns, increased product defect rates, and high losses. The factory relies heavily on diesel generators for backup power, resulting in high fuel costs and serious air pollution. The customer urgently needs a stable, high-power, and cost-effective off-grid power supply solution to ensure continuous production and reduce operational costs.
Location/Time: Northern Nigeria, November 2024
Configuration: PCS: 500kW, BAT: 1200kWh, PV: 400kW, Backup Diesel Generator: 300kW
Load: Production line machinery, air compressors, ventilation systems, factory lighting, office equipment, raw material storage refrigeration equipment
Operating environment: Industrial zone, high temperature, strong sunshine, large dust, frequent voltage fluctuations
Operating modes: Off-grid operation, solar energy priority, energy storage system for peak load regulation, continuous power supply and emergency backup, diesel generator starts automatically only when the power demand of production lines reaches the peak or in continuous rainy days to ensure uninterrupted production.
The system adopts a high-power integrated design with strong load-bearing capacity to meet the high-power demand of manufacturing machinery. It is equipped with a dust-proof, shock-proof and high-temperature resistant shell, which can adapt to the dusty industrial environment and reduce equipment maintenance frequency. The intelligent energy management platform can monitor the operation status of power generation, energy storage and production lines in real time, and adjust power supply according to production needs to avoid energy waste.
Since the system was put into operation, the factory has achieved 24-hour continuous production without shutdowns caused by power outages. The annual fuel cost has been reduced by 60%, the product defect rate has decreased by 25%, and the production efficiency has increased by 30%. This solution not only solves the power supply problem of the manufacturing factory but also reduces environmental pollution, improving the factory’s market competitiveness and profitability.
