Product Description

- Lithium Iron Phosphate (LFP) Battery Pack: Serving as the core energy storage component,which offers a long cycle life, superior safety performance, and stable operational reliability.
- Hybrid Inverter (Megarevo MPS150KW): Enables bidirectional AC-DC power conversion to meet the requirements of power generation and grid integration.
- Integrated BMS and EMS: The BMS works with the battery pack to monitor data in real-time and prevent overcharging, over-discharging, and cell imbalance; the EMS acts as the central control unit, coordinating overall energy dispatch logic.
- Industrial-Grade Air Conditioning/Thermal Management System: The air conditioning unit maintains a constant ambient temperature for the battery cells, effectively extending service life and enhancing system stability.
- Comprehensive Aerosol Fire Suppression System: This automatic fire suppression system comprises the fire piping, exhaust fans, and fire controller shown in the diagram; it activates immediately upon detecting a risk to ensure operational safety.

This 723kWh energy storage container is a core component of the photovoltaic-grid-diesel hybrid microgrid system.
As a critical bidirectional power conversion hub, it stores solar DC power and converts it into AC power usable by industrial loads. Serving as a bridge between photovoltaic modules, the grid, diesel generators, and end loads, it coordinates multi-energy complementarity under the intelligent scheduling of the energy management system (EMS).
It achieves optimized solar self-consumption, peak load shifting, and emergency backup power, stabilizing the power output of the grid system and ensuring a reliable and secure power supply for the factory.
Questions and Answers
Q1: What are the core components of this containerized battery energy storage system?
A: The system consists of a Megarevo 150kW hybrid inverter and a 723kWh high-voltage lithium battery pack. The battery pack contains three high-voltage module groups; each module group consists of 15 51.2V/314Ah battery modules and a high-voltage control box. Accessories, including PDU boxes and battery combiner boxes, are fully equipped, and all components are integrated within a standard 15-foot container.
Q2: What are the main application scenarios for this 15ft containerized energy storage system?
A: Our 15FT energy storage container is moderately sized and highly scalable, making it ideal for the following scenarios:
- Commercial and industrial facilities: Enables peak load shifting, reducing electricity costs for industrial parks, shopping malls, and manufacturing plants.
- Off-grid microgrid projects: Provides reliable, independent power supply to remote mining areas, isolated islands, and areas without electricity.
- Renewable energy power plants: Stabilizes the volatility of solar and wind power generation, reducing generation fluctuations.
Q3: Can this 15FT containerized systems operate stably in extreme high or low temperatures?
A: Absolutely. Each 15ft energy storage container is equipped with a complete industrial-grade thermal management system. Internal air conditioning and insulation ensure that the battery cells operate within their optimal operating temperature range of 15°C to 25°C, even in ambient temperatures ranging from -20°C to 50°C. This design maintains the battery's cycle life and charge/discharge efficiency without affecting its performance, even under harsh extreme climatic conditions.
Q4: What are the advantages of containerized energy storage systems compared to traditional stationary energy storage systems?
A: The 15ft container offers superior integration, greater mobility, and a lower total cost of ownership. Traditional stationary energy storage power stations require significant time for on-site construction and cannot be relocated after installation. In contrast, standardized, plug-and-play 15ft containers significantly reduce on-site civil engineering and construction costs. After project completion, the entire unit can be completely transported and reused for other purposes, significantly improving asset utilization.
