Product Overview
Our Custom Low Voltage Distribution Boxes are versatile, high-durability solutions designed for both standard industrial power distribution and specialized Photovoltaic (PV) solar applications. Whether used as an AC/DC combiner box for solar arrays or a centralized control panel for outdoor industrial machinery, these enclosures provide a secure, climate-protected environment for your electrical components.
Each unit is custom-engineered to meet specific project requirements, integrating high-quality circuit breakers, surge protective devices (SPD), and monitoring tools into a rugged, outdoor-rated housing.
Key Technical Advantages
- Superior Weatherproofing (IP65/IP66): Designed specifically for harsh outdoor environments. The enclosure features a high-density polyurethane sealing strip and a rain-shield roof design to prevent water, dust, and corrosive moisture from entering.
- Specialized PV Integration: Optimized for solar energy systems, our panels can handle both DC string combining and AC grid-tie distribution, featuring dedicated DC fuses and surge arrestors to protect inverters from lightning strikes.
- Rugged Enclosure Material: Available in high-strength cold-rolled steel (powder-coated), stainless steel (304/316), or glass-fiber reinforced polyester (SMC) for maximum corrosion resistance in coastal or industrial zones.
- Thermal Management: For high-load applications, panels can be equipped with filtered ventilation louvers or internal heating/cooling elements to maintain stable operating temperatures for sensitive electronics.
- Safety & Security: Features a multi-point locking system and a transparent inner door (optional) that allows for visual inspection of breaker status without exposing live parts to the elements.

Primary Application Scenarios
- Solar Photovoltaic Systems: Acting as an AC/DC combiner box to merge multiple strings of solar panels before entering the inverter.
- Industrial Automation: Outdoor control panels for water pumps, irrigation systems, and conveyor belts.
- Telecommunications: Power distribution for remote base stations and 5G infrastructure.
- Construction Sites: Temporary power distribution boxes that require high impact resistance and portability.
Why Choose Our Custom Distribution Solutions?
- Fully Pre-Wired Options: We offer "turnkey" panels. Provide us with your electrical schematic, and we will deliver a fully assembled, labeled, and tested box ready for immediate site installation.
- Component Versatility: We can populate your panels with world-class brands (Schneider, ABB, CHINT) or high-quality cost-effective alternatives depending on your budget.
- Anti-Corrosion Longevity: Our steel enclosures undergo a multi-stage pickling and phosphating process, ensuring the paint doesn't peel or rust even after years of UV and rain exposure.
- Expert Engineering Support: Not sure which components you need? Our technical team assists in calculating load requirements and selecting the appropriate surge protection levels.
FAQ
Q: Can this box be used in high-salinity coastal environments?
A: Yes. For coastal areas, we recommend our 316 Stainless Steel or Fiberglass (SMC) enclosures, which offer the highest level of resistance to salt spray and chemical corrosion.
Q: Do you provide the internal components or just the empty box?
A: We do both. We can supply empty IP65 enclosures for your own assembly or provide a fully integrated control panel based on your Single Line Diagram (SLD).
Q: Is the box lockable?
A: Absolutely. Every outdoor panel comes with a standardized industrial lock and key to prevent unauthorized access and tampering.
