All-in-One PVDG Microgrid Container
Powering commercial facilities, industrial operations, and isolated microgrids requires an energy infrastructure that balances reliability, efficiency, and seamless operation. Our containerized Battery Energy Storage System (BESS) is engineered as a complete, factory-integrated solution-combining high-safety LiFePO4 batteries, a robust Power Conversion System (PCS), multi-channel MPPT solar controllers, and a dedicated generator interface within a single, highly durable enclosure.
Whether you are looking to lower demand charges through peak shaving, establish a resilient backup power architecture, or deploy an off-grid microgrid combining solar and diesel generation, this modular BESS container delivers high performance and quick on-site deployment.
Key Features
Modular Scalability (Supports Multiple Units in Parallel)
Expanding energy infrastructure should not require complete system overhauls. Built with modularity at its core, our battery energy storage system supports multiple units in parallel. This architecture enables commercial operators and EPC engineers to scale up power capacity and energy duration incrementally as site demands grow, ensuring minimal upfront risk and maximized long-term investment protection.
UPS-Grade Off-Grid Transfer (<10ms)
For high-precision industrial lines, data facilities, and critical commercial loads, even a momentary power dip can be catastrophic. Featuring an exceptional on/off-grid switching time of less than 10ms, the system provides automatic, ultra-fast transition between utility power and stored energy. It effectively operates as a heavy-duty, utility-scale uninterruptible power supply, isolating sensitive operations from voltage fluctuations and grid blackouts.
All-in-One PVDG Integration (LiFePO4 + PCS + MPPT + Generator Port)
Eliminating the complexity of multi-vendor engineering, this system integrates a high-safety LiFePO4 Battery, Power Conversion System (PCS), multi-channel MPPT, and a dedicated Generator Port into a single pre-engineered container. By seamlessly bridging solar arrays, battery storage, and local diesel generation, this plug-and-play architecture drastically slashes on-site wiring complexity, deployment time, and installation labor costs.

Primary Project Applications
- Commercial & Industrial Peak Shaving: Lower utility charges by storing low-cost solar or off-peak grid energy and discharging during high-rate peak demand hours.
- Island & Remote Microgrids: Provide stable 24/7 power for off-grid communities, resorts, and agricultural operations by integrating solar arrays with existing diesel generators.
- Mining & Heavy Industry Sites: Deliver heavy-duty industrial backup power and smooth out fuel consumption spikes on diesel-powered isolated grids.
- Critical Facilities Backup: Protect data hubs, cold storage facilities, and production lines with reliable, sub-10ms emergency power transition.
FAQ
Q: Which communication protocols do the built-in EMS and BMS support for third-party SCADA integration?
A: The system natively supports Modbus RTU (RS485), Modbus TCP/IP (Ethernet), and CAN bus protocols. This enables seamless, real-time data monitoring and control interfacing with third-party SCADA systems, industrial PLCs, or remote cloud monitoring platforms.
Q: The specification sheet states the system supports multiple units in parallel. Is there a maximum limit?
A: Our standard control architecture supports up to 4 units in parallel without requiring external master controllers, allowing you to scale up to over 1.5MW of power and 3MWh of capacity.
Q: Can the MPPT channels operate independently? How do they handle partial shading or asymmetrical solar strings?
A: Yes. The 240kW models feature 2 independent MPPT channels, and the 360kW models feature 3 independent channels. Each channel operates with its own maximum power point tracking loop within a wide voltage range of 250~850Vdc.
Q: What safety certifications do the battery cells and the entire containerized system hold?
A: The individual LiFePO4 cells are certified to international standards, including IEC 62619 and UN38.3. The entire containerized assembly is engineered to comply with IEC 62477-1 (PCS safety) and CE directives.
Q: What is the standard warranty period, and what is the expected cycle life of the LiFePO4 battery bank?
A: We offer a standard 5-year comprehensive warranty on the entire system, with extended warranty options available for the battery bank up to 10 years.
