OutBack Power EnergyCell 5 Receives UL 9540 Certification
COMMERCE, Texas — OutBack Power, a leading provider of advanced energy storage and power conversion solutions, announced that its EnergyCell 5 battery system has received UL 9540 certification, marking a significant milestone in the company’s commitment to delivering safe, reliable, and code-compliant energy storage solutions for residential and light commercial applications. UL 9540 is the recognized safety standard for Energy Storage Systems (ESS), evaluating the complete integration of battery technology, battery management systems, and power conversion equipment. The certification provides installers, distributors, permitting authorities, and homeowners with increased confidence that the system meets rigorous safety and performance requirements. The EnergyCell 5 is OutBack Power’s next-generation lithium iron phosphate (LiFePO4) battery platform, designed to provide scalable energy storage for backup power, self-consumption, and energy independence applications. Featuring a modular stackable architecture, integrated battery management system, automatic stack communication, and an IP65-rated enclosure, the EnergyCell 5 is engineered for both indoor and outdoor installations. “Achieving UL 9540 certification is an important milestone for the EnergyCell 5 and reinforces our commitment to delivering safe, reliable, and installer-friendly energy storage solutions,” said Randy Taylor, General Manager of OutBack Power. “The EnergyCell 5 was designed not only to meet the highest standards for safety and performance, but also to simplify deployment in the field. Its modular, stackable architecture allows installers to avoid the challenges associated with heavy wall-mounted battery systems, reducing installation complexity and expense, making it easier for smaller crews to complete projects efficiently. Combined with a recent reduction in the EnergyCell 5’s price, we’re making it easier than ever for homeowners and installers to access a high-performance energy storage solution.” The EnergyCell 5 offers: Modular, stackable architecture supporting system expansion as energy needs grow Mobile monitoring app for real-time battery status, performance insights, and system visibility Lithium iron phosphate (LiFePO4) chemistry for enhanced safety and longevity Integrated intelligent battery management system (BMS) Automatic battery identification and communication capabilities IP65-rated enclosure for indoor and outdoor installations Up to 8,000 cycle life and a 10-year warranty Integrated safety features including internal fire suppression technology As energy storage adoption continues to grow, UL 9540 certification is increasingly important for permitting, inspection, and code compliance requirements across North America. The certification helps streamline project approvals while providing assurance that energy storage systems have been evaluated as an integrated solution.

OutBack Power Announces Strategic Supply Agreement with Near Prime Technologies to Support U.S. Manufactured Battery Systems
COMMERCE, Texas — OutBack Power, a leader in off-grid and hybrid solar energy solutions, today announced a strategic Supply Agreement with Near Prime Technologies (NPT), the U.S. manufacturing partner of C4V, a New York-based technology company that has successfully deployed its defense-qualified lithium-ion battery technology across multiple U.S. and allied naval programs. This partnership unites OutBack Power’s leadership in reliable distributed energy with C4V’s proven battery technology and Near Prime Technologies’ domestic manufacturing capability. Near Prime’s U.S.-made battery cells are listed to UL 1973 and UL 1642, and the system architecture has completed UL 9540A thermal‑runaway fire propagation testing. The partnership will enable OutBack Power to offer a secure domestic supply and production of advanced, certified battery systems for residential and commercial energy storage, leveraging C4V’s BMLMP (BioMineralized Lithium Mixed Metals Phosphate) chemistry and Near Prime’s state-of-the-art production facility in New York. The systems reflect completed UL 9540A testing and UL 1973/UL 1642 listings. The agreement focuses on OutBack Power led design, manufacture, and supply of advanced battery systems for the residential market. Under the contract, OutBack will integrate C4V’s proven BMLMP cell technology, manufactured in the United States by Near Prime, into OutBack’s next-generation storage products. Assembly and commercialization of the final systems will be driven by OutBack Power as a fully domestic residential energy storage solution. “By partnering with Near Prime and C4V, we are aligning with a U.S.-based, defense-certified supply chain that ensures the long-term reliability, safety, and domestic energy independence our customers demand. This is another major milestone in OutBack’s transformation,” said Randy Taylor, General Manager of OutBack Power. Under the contract, OutBack Power has committed to purchasing 2GWh of battery cells over the next 5 years. The agreement also includes options for annual renewals and volume expansion through 2030. “This is about building resilience and trust,” said James Showalter, CEO of Energy Access Innovations (EAI), OutBack’s parent company. “We’re reshoring production, investing in long-term partnerships, and delivering on our promise of reliable, accessible energy for all. This is the same technology that has passed the U.S. Department of Defense qualification and are deployed in autonomous naval systems. We’re reshoring production, investing in long-term partnerships, and delivering defense-grade reliability to residential energy users.” “This partnership with OutBack Power represents a natural extension of our mission to bring world-class, U.S.-made battery technology to every sector of the energy market,” said Shailesh Upreti, CEO of C4V and Near Prime Technologies. “Our cells have already proven themselves in some of the most demanding defense and maritime environments. Bringing that same level of reliability and safety to the residential market reinforces America’s retaking leadership in advanced energy manufacturing.” The collaboration also includes joint development of a custom Battery Management System (BMS) tailored to OutBack’s 28S1P, 103.5V, 40A architecture, optimized for C4V’s 53Ah, 3.7V U.S.-made cells. The system will meet both UL and DoD safety and performance standards, ensuring a consistent platform for residential, commercial, and defense-derived energy applications. This partnership unites OutBack Power’s leadership in reliable distributed energy with C4V’s proven battery technology and Near Prime Technologies’ domestic manufacturing capability—establishing a U.S.-made, fully certified, defense-qualified energy-storage platform ready for residential and commercial deployment.
