Our Custom Battery Energy Storage Enclosures
We manufacture custom sheet metal enclosures for battery energy storage systems, including BESS cabinets, battery racks, and integrated storage housings. Our solutions support customized dimensions, ventilation layouts, cable management, mounting structures, and protection designs for different ESS applications. With precision fabrication and flexible OEM capabilities, we help energy storage manufacturers develop reliable enclosure solutions from prototype to mass production.
Key Advantages of Our BESS Enclosures
Our custom battery storage cabinets adopt safety-focused structures to fit indoor and outdoor energy storage projects.
Enhanced Safety Build Thickened steel panels paired with pressure relief valves and blast windows reduce lithium battery thermal hazards. Outdoor powder coating resists rust, scratches and corrosion. Efficient Cooling & Wiring Layout Perforated ventilation louvers stabilize internal battery temperature. Pre-reserved wiring ports and lockable doors simplify routine equipment maintenance. Mobile casters are optional for easy relocation. Flexible Custom Modular Design Adjustable internal brackets fit different battery modules. Two main styles available: stackable indoor housings and heavy-duty outdoor station cabinets. All internal cutouts and compartments can be customized as required.
