Sollega: Pioneering UL3741 Compliance in Solar Racking

The solar industry’s rapid evolution demands solutions that blend innovation with safety. Among recent advancements, UL3741 certification stands out, revolutionizing photovoltaic (PV) hazard control. This certification enables PV systems to eliminate module-level power electronics (MLPEs) and rapid shutdown devices (RSDs), offering a streamlined, cost-effective approach. Sollega alongside SMA took the lead, bringing the first UL3741-certified racking system, the FR510-6°, to market.
What is UL3741 and Why It Matters
UL3741 certification establishes rigorous safety standards for PV systems, particularly addressing fire and electrical hazard control. Currently, compliance with rapid shutdown requirements relies on additional components like RSDs or MLPEs, which increases costs and system complexity. UL3741-certified systems bypass these elements, simplifying installations while maintaining robust safety standards.
Sollega’s FR510-6° exemplifies the transformative potential of UL3741 certification. By integrating safety compliance into its racking design, the FR510-6° eliminates the need for RSDs and MLPEs, reducing on-roof DC connections to one-third of what they would otherwise be. Constructed from BASF’s Ultramid Nylon 6™, a non-conductive, UV-resistant material, the FR510-6° mitigates electrical transfer risks while delivering strength and durability. Its design is ideal for diverse and challenging environments, including corrosive marine climates and industrial rooftops, and is also suitable for ground mount PV installations.
The Sollega FR510-6°: Setting the Standard
The FR510-6° represents a new benchmark in PV racking. Its one-piece, fully ballasted (or hybrid) design simplifies installation and reduces costs. As the first racking system certified to UL3741, it combines innovation, performance, and compliance in a single product.
Engineered with modern needs in mind, the FR510-6° supports large-format modules up to 46″ wide, offering unmatched compatibility and flexibility. Its injection-molded design minimizes roof impact with lightweight, roof-friendly properties. Proudly made in the USA and fully recyclable, the FR510-6° reflects Sollega’s commitment to sustainability and quality.
