Solar arc out boxes" refers to a specific product, commonly known as an
ArcBox, which is an enclosure designed to mitigate fire risks from electrical arcing in solar PV DC connectors.
Primary Benefit: Fire Safety
The main benefit of a solar ArcBox is to dramatically increase the fire safety of a solar installation. In the event that an electrical arc fault occurs within the DC connector (due to issues like poor crimping, moisture ingress, or cross-mating different connector brands), the high-temperature ceramic material of the ArcBox is designed to contain the arc and prevent the spread of fire to surrounding combustible materials like roof battens or membranes.
Other Key Benefits
Property Protection: It protects the surrounding structure and materials, which is especially critical in high-consequence locations like schools, hospitals, commercial buildings, and care homes where operational downtime would be impactful.
Moisture Protection: The enclosure prevents water accumulation and corrosion around the DC connection points, minimizing future arcing risks caused by environmental factors.
Peace of Mind: Provides property owners and installers with greater confidence in the safety and reliability of the solar PV system.
Compliance & Risk Reduction: Essential for risk control and meeting safety standards in specific environments.
Ease of Installation: The simple, snap-shut design means it can be installed quickly without requiring complex procedures or significant extra time.
Durable Design: Constructed from lightweight, high-quality, heat-resistant materials (similar to those used in crucibles and furnaces) for long-lasting performance.
