Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
Our wall-mounted lithium battery storage metal housings are professionally customized sheet metal casings dedicated to residential rooftop solar energy storage, home off-grid backup power, small household BESS systems. Optimized wall-hanging stress dispersion structure effectively averts cabinet sagging and deformation after long-time wall mounting; pre-set adjustable mounting holes adapt to various wall materials including concrete, brick and wooden wall. Integrated sealed structure reaches IP54 dustproof & moisture-proof grade, protecting internal LiFePO4 battery packs, BMS circuit boards and wiring harnesses from indoor dampness, dust erosion.
All cabinet overall size, wall hanging position, heat dissipation louver layout, cable inlet ports, door lock structure, internal battery compartment layout, surface color and brand silkscreen can be fully customized to match your battery size, indoor installation space and household environment demands.
