At EcoFasten, we’re not just passionate about making solar safer and more efficient, we’re experts in it. Our most significant achievement in this mission is our compliance with UL 3741, the Standard for Photovoltaic Hazard Control. Integrated into the 2020 National Electric Code (NEC), UL 3741 sets clear guidelines to enhance the safety of photovoltaic (PV) systems, giving both installers and end-users greater peace of mind.
What UL 3741 Compliance Means for EcoFasten Solutions
UL 3741 certification for our RockIt and ClickFit systems means these racking solutions meet rigorous safety standards. This is achieved without requiring Module-Level Power Electronics (MLPE) in every case. Instead, we have simplified the overall system design using Photovoltaic Rapid Shutdown Equipment (PVRSE), such as Tesla’s Mid-Circuit Interrupter (MCI). The MCI plays a crucial role in our system design, ensuring rapid and safe shutdown of the PV system in case of emergencies. Fewer components mean fewer potential failure points, improved system reliability, and lower service costs. It’s a win/win for everyone.
The Role of Wire Management in Solar Safety
Proper wire management is more than just an installation detail—it’s a cornerstone of safety and reliability. By securely routing wires under solar modules or through approved raceway systems, we help reduce exposure to hazards and make systems safer for first responders in emergencies. This extra attention to detail also helps ensure the system operates smoothly for years to come.
Collaborating with Industry Leaders for Better Results
At EcoFasten, we understand that collaboration is the key to progress in the solar industry. That’s why we’ve partnered with industry-leading companies to deliver flexible and compatible solutions. We’re all in this together.
Our RockIt and ClickFit systems are UL 3741 listed for use with Tesla’s MCI-2 PVRSE and their Powerwall+ and Powerwall 3 Power Conversion Systems (PCS). When paired with specific Solis inverters, they’re also compatible with MidNite Solar’s PVRSE (MNSSR-600S-SS).
Committed to a Safer, Smarter Solar Industry
Our UL 3741 compliance is a testament to EcoFasten’s unwavering commitment to creating safer, more reliable solar solutions. We’re not just working to raise the bar for the entire solar industry; we’re setting the standard by aligning with NEC requirements and continuously improving our products. Whether you’re an installer or a homeowner, our innovative racking systems are designed with your safety, efficiency, and long-term success in mind.
