Viridi's RPS150 Battery Energy Storage System receives Intertek's UL 9540 (cETLus) certification
In a significant development for the energy storage industry, Viridi, a leading company in sustainable energy solutions, has announced that its RPS150 Battery Energy Storage System (BESS) has been awarded the UL 9540 Intertek (cETLus) Listing. This certification underscores the system's compliance with the highest industry safety standards, particularly in real-world conditions.
Jon M. Williams, CEO of Viridi, stated that the listing reinforces the RPS150's ability to meet the highest industry safety standards, addressing fire safety, electrical safety, and overall system reliability. Williams emphasized that stakeholders are demanding solutions that are both high-performing and inherently safe, and Viridi's RPS150 is answering this demand.
The RPS150 system's key safety features are grounded in its fail-safe design and rigorous testing, including passing public fire tests. The system has undergone successful public fire testing, ensuring it can safely manage thermal events and minimize fire risks. It also meets the requirements for the cETLus mark, a recognized certification for compliance with North American safety standards.
The RPS150 system incorporates safety mechanisms that enable it to operate safely in urban and commercial environments, demonstrating reliability under demanding conditions. This accomplishment reflects Viridi's leadership in fail-safe battery energy storage technology, emphasizing enhanced operational safety and robust fire protection capabilities integrated into the RPS150 system.
Unfortunately, specifics such as the exact fire protection technologies, fault detection, or thermal management features of the RPS150 were not detailed in the search results, but the UL 9540 certification itself confirms comprehensive compliance with high safety standards.
The need for safer energy storage solutions is becoming increasingly urgent, as incidents involving lithium-ion battery fires are on the rise. In New York City, for instance, there were 277 fires attributed to lithium-ion batteries in 2024, up from 268 in 2023. Similarly, Phoenix, Arizona reported 127 fires between June 2023 and September 2024, more than doubling the annual average, due to lithium-ion battery incidents.
With the RPS150 Battery Energy Storage System now authorized to carry the cETLus mark for both U.S. and Canadian markets, it is positioned as a solution that meets the highest industry safety standards. The system has already demonstrated its anti-propagation technology in real-world conditions, as it successfully contained a thermal runaway event in a single cell with no flame spread at "The No Heat Zone" event.
Williams stated that the company is setting a new benchmark for safe energy storage with the RPS150, emphasizing that Viridi is answering the demand for safer energy storage solutions. The RPS150 Battery Energy Storage System, with its ETL listing to UL 9540 and proven anti-propagation technology, is positioned as a leading solution for safe deployment in occupied spaces.
The RPS150 Battery Energy Storage System, by Viridi, has been awarded the UL 9540 Intertek (cETLus) Listing, which positions it as a technology that meets the highest industry safety standards in data-and-cloud-computing and technology-driven energy storage systems. The system's anti-propagation technology, demonstrated in real-world conditions, underscores its compliance with North American safety standards and its ability to answer the demand for safer energy storage solutions.
