Fluence Unveils Smartstack, a High-Density AC-based Energy Storage Platform with a Breakthrough Modular Design

ARLINGTON, Va., Feb. 13, 2025 (GLOBE NEWSWIRE) -- Fluence Energy, Inc. ("Fluence") (NASDAQ: FLNC), a global market leader delivering intelligent energy storage, services, and asset optimization software, today announced Smartstack™, a high-density, AC-based energy storage platform, now commercially available for grid-scale applications worldwide with customer deliveries scheduled to begin in the last quarter of 2025. Combining smart performance, predictive servicing, top safety levels, and a future-ready modular design, Smartstack addresses critical industry challenges brought on by unprecedented growth and demand including performance, transportation logistics constraints, and land use. Smartstack’s patent-pending design strategically splits battery storage systems into units with easily transportable weight and dimensions, reducing shipping constraints and installation complexity. Onsite, the system maximizes project site density, delivering up to 7.5 MWh energy density when integrating three hundred Amperes hour (Ah) generation batteries. This density is approximately 30% higher than currently available AC-based systems. The platform enables more MWh generation within existing project footprints, reducing costs and making previously constrained sites viable for storage project development. Smartstack reimagines energy storage design through a flexible modular architecture that can be tailored for varying market needs. 2-hr and 4-hr storage durations as well as longer 6-hr and 8-hr durations are all available for sale now. The market urgently needs systems that can scale quickly and affordably while maximizing availability during peak demand events. The product’s proprietary form factor includes two key components: Smart Skid – A base platform that houses the brains of the Smartstack system. The Smart Skid integrates advanced cooling equipment, power control system hardware, all cabling, and comprehensive monitoring capabilities with convenient maintenance access.Pods – Smartstack battery pods sit atop the Smart Skid and contain the system’s battery cells. Pods support cells from multiple vendors, assuring the most competitive pricing and top performance. The pods are also designed to be swapped with replacement units during maintenance or technology upgrades to maximize system availability. “Fluence’s track record of innovation and speed of execution drive us as we guide the energy storage industry forward. Backed by our industry-leading expertise developing and deploying innovative solutions globally, Smartstack reimagines how systems are designed, built, and maintained,” said Fluence President & CEO Julian Nebreda. “By addressing critical challenges like supply chain shipping constraints, product density, serviceability, and modularity, we are delivering a platform that is more scalable and easier to operate than competing solutions. This translates to superior project economics for our customers.” Guaranteed to deliver up to 99% availability with Fluence’s best-in-class long-term service agreement to help maximize revenue generation, Smartstack's innovative approach makes intelligence, not hardware, the heart of innovation. The platform elevates system intelligence with locally deployed AI, autonomously optimizing embedded controls while providing full visibility across storage portfolios. The modular design of Smartstack enables a more agile and cost-effective supply chain localization strategy, allowing components to be sourced or manufactured regionally to optimize availability, cost, and compliance while enhancing resilience against geopolitical and logistical disruptions. “Smartstack maintains Fluence’s uncompromising commitment to safety and cybersecurity, incorporating multi-layer protection systems,” said Fluence VP of Product and Program Management Mark Berger. “The platform integrates the same industry-leading safety features as our trusted Gridstack products which includes large-scale fire testing certification, now at a much higher density. These advanced safety features work together to prevent, detect, and contain thermal events, minimizing potential damage and downtime. Our unwavering commitment to safety is at the heart of every product we deliver, and Smartstack is no exception.” To date, Fluence has deployed and contracted more than 37.7 GWh of storage projects globally, including the world’s first grid-connected system.
