Solar battery enclosure manufacturing
Precision Sheet Metal Fabrication for Solar Battery Enclosures
Enclosuremfg provides end-to-end sheet metal fabrication for energy storage and industrial OEMs. We produce durable enclosures for residential systems through large-scale industrial BESS, managing the production cycle from structural design analysis to final assembly.

Designed for energy storage
Engineered solutions for solar battery systems
A battery enclosure is a structural and safety-critical assembly—not just a metal box. We fabricate features that support reliable integration for residential and commercial-industrial lithium-ion storage.
01 / Structural strength
Reinforced, high-load chassis
High-capacity base and frame designs support the substantial weight of battery modules and internal rack systems, with stiffness planned for the intended installation.
02 / Electrical isolation
Insulation provisions for battery modules
Precise mounting points accommodate internal insulating liners and ground-fault protection hardware, helping maintain isolation between battery modules and the enclosure frame.
03 / Thermal management
Purpose-designed airflow paths
Precision sheet metal ducts, baffles and airflow-guiding panels help manage the battery compartment’s temperature and reduce the risk of hotspots.
04 / Safety integration
Fire-system and pressure-relief interfaces
We provide planned cutouts and reserved openings for fire suppression equipment and explosion-proof pressure-relief vents, alongside cable-management pass-throughs.
In-house workflow
From cut sheet to finished enclosure
An integrated production line keeps critical processes under direct control and reduces lead-time risks associated with third-party outsourcing.
Discuss your projectCut
12kW and 6kW fiber laser profiling
Processes carbon steel, stainless steel and aluminum with high-speed accuracy and clean edges for critical seal interfaces.
Form
Five CNC press brakes
Supports complex, multi-stage bends for high-stiffness, structural-grade enclosure components.
Fasten
Seven automated hardware insertion stations
Installs PEM nuts, threaded studs and standoffs consistently for internal rack mounting.
Weld
24 specialized welding stations
Laser welding supports low-heat, low-distortion seams; MIG/TIG welding is used for reinforced structural frames.
Finish
In-house 2500 × 6000 mm powder coating line
Multi-stage pretreatment and high-durability coating for large cabinets and structural skids, with direct oversight of coating consistency and adhesion for NEMA/IP-rated environments.
Engineering partnership
DFM support before production begins
Our five-person engineering team works directly with your R&D staff to review enclosure designs and help move them toward manufacturable, production-ready parts.
- 01Identify potential assembly interferences.
- 02Review bend radii and forming requirements.
- 03Improve material utilization without compromising structural performance.
Independent quality control
Dimensional control through the production run
A dedicated six-person QA/QC team manages formal inspection independently of the production floor.
- 1
3D CAD analysis
Verify unfolding parameters and bend allowances.
- 2
Incoming material testing
Inspect sheet thickness and metallurgical specifications.
- 3
First-article inspection
Measure initial units against engineering drawings.
- 4
In-process audits
Check each station for consistency across batch runs.
