Renewable energy penetration keeps rising worldwide, and reliable containerized energy storage systems (BESS containers) have become the core solution for commercial, industrial and utility energy projects. Our 1.2MWh 20GP LiFePO4 container energy storage system is a fully pre-integrated battery energy storage unit built inside a standard 20GP shipping container.
Different from small cabinet-type energy storage products, this 20GP BESS container is designed for large-capacity distributed and centralized energy storage scenarios. It adopts lithium iron phosphate (LiFePO4 / LFP) battery modules, with rated energy of 1.2MWh, rated voltage of 768V and a wide working voltage range of 672V–864V. The whole system supports 0.5C charging rate and 0.5C~1C discharging rate, with up to 96% system efficiency and 90% depth of discharge, delivering stable and high-performance energy output.
This 20GP containerized energy storage system integrates multiple optimized designs to meet outdoor long-term operation requirements.
✅ Long Service Life with 10-Year Warranty The LiFePO4 battery chemistry brings outstanding cycle stability. The complete container BESS is backed by a 10-year warranty, greatly lowering the long-term OPEX for EPC contractors and project owners.
✅ Flexible & Scalable Deployment Based on standard 20GP container dimensions (605824382896 mm), this 1.2MWh energy storage container is easy for sea, land transport and fast on-site installation. Multiple units can be connected in parallel, allowing capacity expansion to match project demand.
✅ Strong Environmental Adaptability Equipped with air cooling thermal management, the container energy storage works stably within 0℃ to 50℃. It supports working humidity from 5% to 95% RH. It is suitable for most outdoor sites, from industrial parks to solar farms, with altitude below 2000m.
✅ High Safety Standard with Modular Fire Protection Safety is the top priority for large-capacity LiFePO4 container battery storage. This system adopts modular fire protection with independent safety isolation partitions inside the container cabin. The isolation design prevents fault spread and minimizes risk during long-running operation.
✅ Modular Battery Design & Higher System Efficiency The energy storage container is assembled by 75 pcs of 51.2V 314Ah LiFePO4 modules in parallel connection. The optimized cluster design eliminates DC circulating currents between battery clusters, lifting usable capacity by 15% and boosting overall efficiency by 2%. Modular configuration also limits fault impact and simplifies maintenance.
✅ Open Communication Protocol for Smart Monitoring It supports CANBUS and Modbus TCP/IP communication modes. The BESS container can be seamlessly connected with SCADA, EMS and cloud monitoring platforms, for real-time data tracking, remote control and intelligent energy scheduling.

This containerized energy storage system fits a wide range of utility and C&I energy storage use cases:
Compared with custom-built room-type energy stations, standard 20GP container BESS has much shorter delivery cycle and less site construction work. All battery modules, cooling units, fire suppression and control systems are pre-assembled and tested inside the container before shipment.
We use mature LiFePO4 cells with excellent safety performance. The air cooling solution is more cost-effective than liquid cooling for medium-temperature regions. With standard open communication protocols, our 1.2MWh BESS container can integrate with most mainstream energy management platforms, bringing great flexibility for system integrators and EPC partners.
If you are looking for scalable, safe and high-efficiency containerized LiFePO4 energy storage for your next PV storage, peak shaving or microgrid project, our 1.2MWh 20GP BESS container is a competitive distributed energy storage option.
Q: Is this 1.2MWh energy storage container air cooled or liquid cooled? A: This 20GP containerized energy storage system uses air cooling temperature control, lower maintenance cost and stable performance for most C&I storage projects.
Q: What communication protocols does the BESS container support? A: It supports CANBUS and Modbus TCP/IP, easy to connect to EMS and remote monitoring platforms.
Q: Can multiple 1.2MWh 20GP BESS containers run in parallel? A: Yes. The parallel design allows you to stack capacity for MW-scale energy storage plants.
Q: What is the warranty period of this LiFePO4 container energy storage system? A: We provide a 10-year warranty for the whole BESS container system.
We provide a one-stop service integrating mature solutions, production, delivery, and after-sales service.
