Custom C&I BESS Power Cabinet | Integrated Energy‑Storage Enclosure – SanJun Hardware

Custom C&I Integrated BESS Power Cabinet Enclosure, Heavy‑Load IP54‑IP55 Sheet‑Metal Housing, OEM ODM Free CAD Design

This custom C&I integrated BESS power cabinet houses battery modules, PCS inverters and thermal management assemblies.

It delivers heavy‑load mechanical protection and IP‑rated dust‑water resistance for commercial‑industrial energy‑storage deployments.

We provide free production‑ready CAD drawings; no self‑designed sketches required.

Industry Pain Points We Solve

Global energy‑storage integrators and EPC contractors frequently face manufacturing obstacles in cabinet sourcing. ‑ Extra high costs for third‑party structural drawing development without mature cabinet designs. ‑ Cabinet deformation caused by heavy battery‑module loads under long‑term running conditions. ‑ Poor matching of internal duct, wiring and component mounting positions leading to difficult assembly. ‑ Inadequate sealing resulting in dust and moisture ingress for indoor and semi‑outdoor sites. ‑ Uneven welding and inferior anti‑corrosion coating shorten cabinet service life.

Our Core Manufacturing Strengths

As a direct sheet‑metal factory, we offer 100% free production‑ready CAD drawing design based on your project requirements. Customers do not need to supply their own sketches.

We adopt thick‑gauge cold‑rolled steel or galvanized steel as raw materials. Full‑process precision fabrication includes laser cutting, CNC bending, heavy‑duty reinforced welding and weather‑resistant outdoor powder coating. Machining tolerance is strictly controlled within ±0.1 mm to guarantee precise fitting for inner BESS components.

The reinforced frame structure effectively prevents cabinet deformation under heavy‑weight battery packs. Pre‑reserved installation positions for cooling ducts, cable routing and power modules simplify field installation and later maintenance. Optional IP54‑IP55 sealing structure ensures stable dust‑proof and waterproof performance for complex working environments.

Full OEM & ODM customizations are supported: adjust dimensions, door layout, ventilation layout, surface RAL colors and laser‑engraved brand logos. Both small‑batch prototype orders and large‑volume project orders are acceptable. Every finished enclosure passes full‑dimension inspection and sealing performance testing before shipment for consistent batch quality.

Application Scenarios

Our C&I integrated BESS power cabinet enclosures apply widely for commercial‑industrial energy‑storage projects, peak‑valley power arbitrage systems, factory backup power supply, solar‑storage hybrid systems, industrial parks and micro‑grid facilities.
