A large-scale logistics warehouse in southern Brazil is responsible for the storage and distribution of food and electronic products. The warehouse is located in a remote logistics park with no public power grid coverage. It used to rely entirely on diesel generators for power supply, which has high fuel consumption, high maintenance costs, and unstable operation. The unstable power supply often leads to the failure of cold storage systems and security monitoring equipment, resulting in food spoilage and potential safety hazards. The customer needs a clean, stable, and low-maintenance off-grid power supply solution to ensure the normal operation of the warehouse.
Location/Time: Southern Brazil, December 2024
Configuration: PCS: 350kW, BAT: 900kWh, PV: 300kW, Backup Diesel Generator: 200kW
Load: Cold storage refrigeration systems, conveyor belts, forklift charging, security monitoring systems, warehouse lighting, office and logistics management equipment
Operating environment: Remote logistics park, high temperature, high humidity, sufficient sunshine, occasional heavy rainfall
Operating modes: Off-grid operation, solar energy priority, energy storage system for stable power output, cold storage temperature control power supply and peak regulation, diesel generator starts automatically in continuous rainy days or peak load periods to ensure the stable operation of cold storage systems.
The system adopts a waterproof, moisture-proof and corrosion-resistant design, which is suitable for the high-humidity environment of the logistics warehouse. It is equipped with an intelligent temperature linkage control system, which can adjust the power supply of the cold storage in real time according to the temperature change, ensuring the freshness of stored goods. The compact design of the system saves warehouse space and is easy to install and maintain.
This solution has effectively replaced the traditional diesel power supply mode, reducing the annual energy cost by 55% and the equipment maintenance cost by 70%. The cold storage system operates stably, and the food spoilage rate has been reduced to zero. The security monitoring equipment runs continuously, ensuring the safety of warehouse goods. It provides a reliable energy support for the efficient operation of the logistics warehouse and promotes the green development of the logistics industry.
