SAN FRANCISCO - October 1, 2025 - SPAN, maker of the nation’s smartest electrical panels, today announced that all four of its newest smart panel models have been certified for performance and safety under UL 3141 certification, the first-ever smart panels to receive the certification. This certification is the latest step in SPAN's long history of working with key stakeholders to develop new product safety standards like UL 3141 to permit new cutting edge electrification technologies that meet the highest levels of safety and reliability.
UL 3141 is the highest safety standard for Power Control Systems (PCS), a category of devices that manage electrical loads to keep power within defined limits. Underwriters Laboratories recently published the 3141 PCS standard in response to the growing number of energy generation, storage, and conversion devices and the increasing complexity of instruments used to coordinate, limit, and optimize their use. The 3141 standard builds on and incorporates prior UL standards for energy management devices, and will be a requirement for PCS applications in the 2026 National Electrical Code.
“A clean energy future must also be a safe energy future for families and companies,” said Arch Rao, CEO of SPAN. “Safety has always been a top priority for us, and the extensive time and resources we’ve spent on achieving this certification were a worthwhile investment in ensuring our customers’ safety and giving them additional peace of mind. SPAN continues to set the industry standard for safety and reliability with our products, and in doing so remove barriers to our mission to enable electrification for all.”
The certification of SPAN smart panels to UL 3141 represents independent verification that its PCS systems effectively protect consumer safety and device integrity while also performing sophisticated energy and power control functions that allow increased home electrification using existing utility infrastructure. SPAN Panel, with the company’s patent pending PowerUp software, helps consumers and electric utilities avoid service upgrades that might otherwise be required to meet homes’ growing demand for electricity and can cost $10,000 or more. These dual benefits help make the electric grid more flexible and reliable while also helping to rein in retail electricity prices at a time when prices are rising rapidly across the U.S.
SPAN has long been the leader in hardware and software that empowers consumers to embrace new and sophisticated technology while taking greater control of the energy they use. Widespread adoption of smarter, more capable, and more efficient electrical appliances and devices will only happen if adopters can rest assured that the new devices they bring into their homes are safe and reliable. SPAN is proud to be the first company in its category to provide this assurance to its customers through certification to the UL 3141 standard and help accelerate the transition to an electrified, safer, and healthier world.
SPAN is on a mission to enable electrification for all and provide energy management for every home. The company designs products that remove barriers to electrification, providing a holistic approach to managing increasing demands on household energy. Powering your home with clean energy should be a simple and delightful experience that is technology-forward and human-centered. For more information, go to www.span.io.
