Problem
Solar photovoltaic (PV) installations are vulnerable to direct current (DC) arcs, which can ignite fires, damage equipment, and pose safety hazards to personnel. Existing fire‑safety measures often require complex wiring or additional components that are difficult to integrate into standard PV arrays.
Solution
ArcBox provides a purpose‑built enclosure that isolates and contains DC arcs within solar connector assemblies. The enclosure integrates directly with PV modules and junction boxes, creating a physical barrier that prevents arc propagation and limits fire spread. Its design complies with industry fire‑safety standards and can be installed using standard mounting hardware, reducing retrofit effort. By containing arcs at the source, ArcBox protects downstream equipment, reduces downtime, and enhances overall site safety without altering the electrical performance of the system.
Target Audience
Primary customers are solar EPC contractors, commercial and utility‑scale PV developers, and safety‑focused installers seeking to meet fire‑safety compliance for new or retrofitted solar projects.
Features
