Our Custom Battery Energy Storage Enclosures

Custom sheet metal integrated energy storage and charging enclosure with louver ventilation, internal compartment layout and lifting lugs for commercial ESS systems

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.

FAQ

What standard sizes are available for energy storage cabinet enclosures used in lithium battery systems?

We supply multiple standard dimensions, custom height, width and depth sheet metal enclosures are supported for different lithium battery pack layouts.

What IP rating do your outdoor energy storage housings reach for dust and water resistance?

Our sealed shells adopt full rubber gaskets, most models reach IP54 / IP55 protection for outdoor commercial energy storage installations.

Can energy storage enclosures be divided into independent compartments for battery packs and PCS?

Yes, separate metal partitions isolate power components, effectively reducing safety risks for lithium battery energy storage systems.

Does electrostatic powder coating prevent rust on outdoor energy storage metal shells?

Thick powder coating offers anti-corrosion and scratch resistance, extending service life for outdoor energy storage equipment housings.

Are full grounding mounting points pre-reserved on all energy storage enclosures?

Every shell reserves complete grounding bolt positions to meet electrical safety standards for lithium battery energy storage projects.

Do your energy storage housings comply with CE and UL certification requirements?

All sheet metal enclosures are manufactured to meet CE and UL safety standards for residential and commercial lithium battery storage systems.

Can you make custom cutouts for cooling fans, air conditioners and wiring ports on storage cabinets?

We support custom laser cutouts for ventilation, wiring and monitoring equipment based on customer technical drawings.
