Product Introduction:
The outdoor commercial and industrial energy storage cabinet (air-cooled) is an energy storage solution that integrates a battery system, a power storage converter (PCS), an intelligent energy management system (EMS), and a thermal management system. Its most prominent feature is its highly integrated design, compacting all core components within a rugged, weatherproof enclosure, simplifying on-site installation. Designed for harsh outdoor environments, it boasts wide temperature adaptability and utilizes efficient intelligent forced air cooling technology to ensure the internal battery cells remain within the optimal operating temperature range.
Advantages:
1. Modular and Flexible Scalability
The energy storage cabinet utilizes a standard modular architecture with flexible capacity configurations, supporting expansion from a base unit of 65kW/131kWh. Users can choose to deploy a single cabinet or connect multiple cabinets in parallel based on their actual load requirements and initial investment budget.
2. Intelligent Air Cooling Technology
The system features an advanced intelligent air cooling system equipped with high-efficiency fans and precise temperature sensors. It intelligently starts and stops in real time based on the cabinet's internal environment and battery cell temperature, forcing external cool air to maintain a stable internal temperature within the optimal range of 25°C ± 3°C. This effectively slows battery degradation, ensuring the system's reliability and long lifespan for continuous high-power operation in all-weather conditions.
3. High System Efficiency
Combined with a high-performance power storage converter (PCS) and a high-efficiency battery system, the system achieves a charge-discharge cycle efficiency of up to 96% under rated operating conditions at a high 1000V DC system voltage. This translates to lower energy conversion losses, allowing more discharged energy to be used in production, and improving the overall cost-effectiveness of the project.
4. Rugged Protection, Unafraid of Harsh Environments
The entire cabinet features an IP54-rated, high-strength casing, effectively protecting against dust intrusion and splashing rain from all directions. The cabinet surface is rigorously treated with salt spray and corrosion-resistant coatings, ensuring it can withstand wind, rain, dust, and the humid and corrosive environments of coastal areas, ensuring long-term stable operation in a variety of complex outdoor industrial scenarios.

What’S News
The Outdoor Commercial & Industrial Energy Storage Cabinet (Air-Cooled) is an integrated energy storage solution designed for complex environments and high-intensity operating conditions. It tightly integrates a battery system, power storage converter, intelligent energy management system, and advanced thermal management system into a single robust and weather-resistant cabinet. This highly integrated structure not only makes the entire system more compact and reliable but also simplifies on-site installation and commissioning, allowing users to deploy and quickly put the system into operation. Its weatherproof outdoor cabinet is made of industrial-grade metal materials, possessing excellent corrosion resistance, dustproof, and waterproof capabilities, enabling the energy storage cabinet to withstand harsh outdoor environments for extended periods, providing continuous, powerful, and secure energy support for commercial and industrial applications.
One of the biggest technological highlights of the air-cooled energy storage cabinet is its highly efficient intelligent forced ventilation cooling system. Compared to complex and expensive liquid cooling solutions, air-cooling technology provides reliable and effective temperature control in a simpler, easier-to-maintain, and more economical way. The system utilizes optimized airflow design, intelligent speed-regulating fans, and a temperature sensor network to manage directional airflow within the cabinet. This allows for rapid cooling of high-temperature areas and maintains a balanced temperature in low-temperature areas, ensuring the battery remains within its optimal operating temperature range throughout its entire lifespan. For energy storage systems operating long-term and undergoing high-frequency cycles, stable temperature control not only extends battery life but also prevents capacity degradation or safety risks caused by localized overheating, providing a strong guarantee for long-term stable system operation.
Regarding core performance, the battery system built into the energy storage cabinet typically employs highly reliable lithium iron phosphate technology, featuring long cycle life, high energy density, and excellent safety characteristics. It can meet the needs of various scenarios, from peak shaving and valley filling, power frequency regulation, to backup power. The PCS (Power Control System) is responsible for bidirectional energy conversion between the battery and the grid. It not only enables highly efficient charge and discharge control but also supports grid-connected operation, islanded mode, and seamless switching, allowing the energy storage cabinet to provide stable power under conditions of grid fluctuations, power outages, or drastic load changes.
The embedded EMS (Energy Management System) acts as the brain of the entire energy storage unit, using intelligent algorithms to analyze and manage power flow in real time. This includes features such as intelligent peak-valley switching based on electricity price fluctuations, optimizing battery utilization, predicting load trends, and coordinating interactions with the photovoltaic system. The EMS also features remote monitoring and data analysis capabilities, allowing users to view battery status, equipment health, and energy flow through a cloud platform or local system. This enables refined operation management and significantly reduces maintenance costs.
Due to its modular design, the outdoor commercial and industrial energy storage unit offers high scalability, allowing for flexible capacity or power expansion as needed. This allows it to be scaled from tens of kilowatts to hundreds of kilowatts or even larger, providing highly adaptable solutions for various industrial power needs, commercial scenarios, or park energy systems. Its enclosed cabinet structure is not only safe and robust but also protects internal components from damage caused by wind, sand, moisture, and temperature differences, further extending the system's actual lifespan.
