The RPSLinkIN 480-V battery system from Viridi has received UL 9540 listing from TÜV Rheinland.
To achieve UL 9540 listing, Viridi completed UL 9540A testing to the residential, indoor, floor-mounted standard for the pack (RPS50kWh). The system met five performance criteria, with no smoke, gas or fire detected during testing. As a result, Viridi systems can be deployed across commercial and industrial settings without the need for additional fire suppression or secondary safety systems.
Designed for safe indoor installation, the RPSLinIN system enables deployment in occupied, space-constrained environments.
“Achieving UL 9540 listing, utilizing UL’s strictest indoor residential test, is a major milestone for Viridi and for the broader energy storage industry,” said Jon M. Williams, CEO of Viridi. “Safety has been one of the primary barriers to scaling battery storage, particularly in critical infrastructure and occupied environments. With RPSLinkIN, we’re enabling organizations to deploy indoor energy storage systems where it wasn’t previously possible — unlocking new opportunities for resilience, cost savings and decarbonization, and representing a fundamental shift in how and where battery systems can be deployed.”
The listing builds on a growing portfolio of real-world deployments demonstrating the system’s performance. These deployments range from indoor installations at the U.S. Dept. of Energy’s Oak Ridge National Laboratory to a 600-kWh indoor energy system at the Hauptman-Woodward Medical Research Institute.
