Lingtech Battery, a trusted manufacturer of advanced containerized energy storage solutions, has successfully delivered a 20-foot 3MWh-1MW battery energy storage system (BESS) featuring a fully integrated AC+DC architecture and built-in liquid cooling technology. This turnkey milestone delivery reinforces Lingtech’s commitment to providing safe, efficient, and plug-and-play energy storage for commercial, industrial, and utility-scale projects around the world.
This system packs 3 megawatt-hours of energy capacity and 1 megawatt of continuous power output into a single standard 20-foot shipping container. The battery, inverter, and cooling system are all integrated inside one unit — no separate containers, no complex on-site assembly. It ships ready to operate and can be commissioned in a matter of days once the site is prepared.
The system is equipped with an advanced liquid cooling system that actively manages the temperature of every battery cell. This ensures uniform heat distribution, eliminates dangerous hotspots, extends the overall cycle life of the batteries, and maintains high performance even in extreme hot or cold climates. Compared to traditional air-cooled systems, liquid cooling delivers greater energy density, higher safety margins, and significantly lower long-term maintenance costs.
One of the most powerful features of this Lingtech BESS is its voltage adaptability. The standard configuration delivers a 400V AC output, which is ideal for commercial and industrial behind-the-meter installations, factory rooftops, and solar-plus-storage setups.
However, Lingtech understands that every project has unique grid connection requirements. That is why this system can be easily customized with step-up transformers to deliver 800V or 11kV output, depending on customer specifications. Whether you are connecting to a low-voltage commercial building or a medium-voltage utility grid, Lingtech configures the system to match your infrastructure — saving you time, engineering costs, and installation headaches.
This flexibility makes the 3MWh BESS suitable for a wide range of applications, including peak shaving, demand charge management, frequency regulation, renewable energy integration, microgrid support, energy arbitrage, and off-grid power supply.
Traditional battery storage projects often require multiple separate containers — one for the battery rack, another for the power conversion system, and sometimes a third for transformers or switchgear. This adds logistics complexity, increases footprint, and drives up installation costs.
Lingtech’s integrated AC+DC design solves all of this. By combining the DC battery system and the AC inverter/conversion system into a single 20ft container, Lingtech delivers a truly all-in-one solution. The result is a smaller site footprint, faster deployment, lower shipping costs using standard container logistics, and a simplified commissioning process. The system arrives factory-tested and site-ready.
This 3MWh-1MW liquid-cooled BESS is designed to serve a broad spectrum of energy storage needs:
Lingtech Battery is a professional manufacturer specializing in containerized battery energy storage systems. The company focuses on research, development, and production of integrated liquid-cooled BESS solutions with flexible voltage configurations. Lingtech serves customers across Europe, North America, the Middle East, Southeast Asia, Africa, and other global markets. With a strong emphasis on product quality, safety, and customer satisfaction, Lingtech Battery is helping accelerate the worldwide transition to clean, reliable, and affordable energy storage.
