This system is an uninterrupted power supply and end-to-end distribution solution designed for industrial and commercial photovoltaic projects. It is composed of a 400A ATS dual power switch cabinet and a 400A branch distribution box, covering the full chain distribution needs from power switching to terminal loads.

400A ATS Dual Power Transfer Cabinet: Enables automatic/manual seamless switching between the main PV power supply and mains/backup generator. It monitors the status of both power sources in real time and switches within seconds during faults, ensuring uninterrupted power supply for the entire system.

400A Branch Distribution Cabinet: Receives stable power output from the ATS cabinet, distributes power accurately to terminal loads via multiple branch circuit breakers, and provides dual overload and short-circuit protection at both the main circuit and branch levels. A fault in one branch only trips its own breaker without affecting the upstream PV system or other loads.

Full-Loop Closed-Loop Power Distribution: The ATS cabinet guarantees power continuity, while the branch cabinet enables safe terminal distribution, forming a complete PV power distribution chain of "uninterrupted switching + tiered protection".

Reliable & Low-Maintenance: Uses core components from the same brand for high compatibility and low failure rates. Pre-assembled and pre-tested at the factory, it only requires cable connection on-site for commissioning, significantly shortening construction time.

Safe, Compliant & Expandable: Industrial-grade IP-rated enclosure with insulation protection design, compliant with IEC standards. Supports customization of ATS switching logic, branch quantity and current specifications to adapt to future project expansion needs.

Commercial/Industrial Rooftop PV Projects: Uninterrupted power supply for factories, shopping malls and office buildings.

Off-Grid/Remote Site PV Systems: Dual power supply of PV + generator to solve issues with unstable or unavailable mains power.

Small Data Centers/Equipment Rooms: Power distribution for loads requiring high power continuity.

Industrial Workshop PV Retrofits: Terminal distribution and tiered protection for workshop equipment and lighting systems.
