نظرة عامة على المنتج
Our stackable lithium battery storage metal enclosures are tailor-made sheet metal housings specially designed for solar photovoltaic energy storage, off-grid power supply and commercial BESS systems. Reinforced stacking frame structure supports multi-layer vertical stacking, with precise positioning lugs to control interlayer gap ≤0.05mm, single cabinet load up to 300kg. Integrated full sealing structure achieves IP54/IP65 waterproof, dustproof and anti-corrosion performance, effectively protecting internal LiFePO4 battery modules, BMS, wiring harness and control components from rain, sand, humidity and salt spray erosion.
All cabinet dimensions, stacking height, ventilation louvers, cable inlet ports, lock structure, mounting brackets and surface colors can be fully customized to match your battery layout, installation space and outdoor harsh environment requirements.
2. Core Advantages & Industry Pain Points We Have Overcome
✅ Exclusive Edge: 100% Free CAD Drawing & DFM Analysis
Most sheet metal factories require buyers to supply complete engineering drawings before quotation and production. SanJun Hardware breaks this threshold: you only need to inform us your battery size, stacking layers, IP protection grade, heat dissipation demands and installation scenarios. Our senior new energy engineering team completes all structural design, DFM manufacturability optimization and production drawings free of charge. You do not need to prepare any sketches or drafts by yourself, greatly cutting your R&D outsourcing cost and project trial risks. We revise drawings repeatedly until fully matching your stacking assembly demands.
✅ Technical Bottlenecks Solved via Precision Sheet Metal Craft
- Solved stacking frame bending & welding deformation: Thickened reinforced bearing frame eliminates thermal distortion, keeps multi-layer stacking stable without tilting
- Fixed interlayer positioning clearance mismatch: Custom precision positioning lugs control gap within 0.05mm, easy modular assembly
- Improved sealing failure & water ingress: Custom integrated rubber sealing strips, stable waterproof performance under temperature & humidity fluctuation
- Resolved uneven powder coating & coastal salt spray corrosion: Multi-layer outdoor weather-resistant electrostatic powder coating, C3/C4 anti-corrosion grade for seaside projects
- Optimized thin plate springback & batch dimensional inconsistency: CNC precision bending & fixture calibration, consistent tolerance ±0.1mm for mass production
- Enhanced heat dissipation design: Custom vent louver layout to avoid battery overheating during long-term operation
✅ Full In-House One-Stop Fabrication Workflow
Whole production procedures finished inside our factory without outsourcing: Laser Cutting → CNC Precision Bending → Seamless TIG/MIG Welding → Deburring & Polishing → Outdoor Anti-Corrosion Powder Coating → Stacking Frame Assembly & Sealing Test. Unified quality control, shorter lead time and lower comprehensive procurement cost for global new energy manufacturers.
