“Small connector. Serious risk point.”
In many PV installations, the first practical protection focus should be the end-of-string and extension-cable connector points where human-made connections are most common. These are the areas where connector mismatch, poor crimping, moisture ingress, cable tension and workmanship issues can increase DC risk.
First defence
Protect the human-made DC connector points
In many PV installations, the first practical protection focus should be the end-of-string and extension-cable connector points where human-made connections are most common. These are the areas where connector mismatch, poor crimping, moisture ingress, cable tension and workmanship issues can increase DC risk.
End-of-string connections
A key first-defence point where site-made or extension-cable connections are often introduced into the PV string.
Connector mismatch & crimp risk
Cross-mated MC4-type connectors, poor crimping, wet assembly or cable tension can all increase connector failure risk.
Consequence multipliers
Vegetation, bird nests, leaves, debris, combustible roofs or flammable materials can increase the consequence of a DC connector fault.
Interested in ArcBox for your PV projects?
Whether you are an installer, EPC, solar shop, facilities manager, insurer, maintenance provider or PV safety partner, ArcBox offers a practical way to improve connector protection across South African PV installations.
Arcbox
The Viridian Solar ArcBox ARC04-01 is a solar PV connector enclosure designed to provide additional protection around suitable PV DC connector points. It supports improved connector management, weather protection and fire-risk reduction in residential, commercial and rooftop solar installations.
Optional ARC-M01-01 ArcBox Rail Mounting Bracket for 8/10 mm rail applications is available separately where required.
ArcBox Rail Mounting Bracket (Single unit)
The ARC-M01-01 ArcBox Rail Mounting Bracket is designed to secure the ArcBox connector enclosure to compatible solar PV mounting rails using either an 8 mm or 10 mm T-bolt. The bracket can be rotated before fixing to help align the ArcBox with the PV cabling route.
