SanJun Hardware is a professional precision sheet metal manufacturer focusing on custom stackable lithium battery storage enclosures for solar PV energy storage systems. We adopt carbon steel, galvanized steel and stainless steel as raw materials to produce high-load stackable battery cabinets with stable stacking positioning, IP-rated waterproof & dustproof, anti-corrosion and anti-vibration performance for household & commercial energy storage projects.
Our core competitive advantage: we provide free full structural CAD drawing design according to your technical demands, no ready drawings required from buyers. Our one-stop in-house production resolves mainstream industry processing defects including cabinet stacking deformation, poor layer positioning clearance, uneven sealing, weak load-bearing and inconsistent batch dimensional tolerance. We fully support OEM & ODM customization for all capacity energy storage systems, small trial orders and mass bulk production.
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.
