Fortress Power eForce 28.8KWH Modular 200AH 48V Battery

Fortress Power eForce 28.8KWH Modular 200AH 48V Battery Description: The eForce Stackable Energy Storage System is Fortress Power’s most advanced and scalable solution for whole-home backup, off-grid living, and solar self-consumption. Each 9.6 kWh lithium iron phosphate (LFP) battery is designed for long-lasting performance with 8,000 cycles and a 20-year design life, making it ideal for residential and light commercial applications. Engineered for flexibility, eForce modules can be stacked vertically (up to 3 modules) using wireless quick-connect plugs — no cables required — or expanded laterally for systems up to 268.8 kWh. Each stack integrates with the eWay, a smart wireway featuring built-in busbars, conduit ports, an emergency shutoff, and real-time LED status indicators. The Envy Inverter mounts directly to the eWay, forming a streamlined, weather-resistant (IP65) energy tower. This modular architecture enables effortless installation, seamless AC/DC coupling, and full compatibility with Fortress Power’s monitoring app. Whether you’re building a new solar storage system or upgrading an existing one, the eForce delivers clean, reliable power and unmatched scalability — all backed by an industry-leading warranty for long-term confidence and protection.   FEATURES  Built with premium lithium iron phosphate (LFP) cells rated for 8,000 cycles and fast-charging capability without compromising performance or longevity. The integrated design eliminates the need for wireways, long cable runs, and additional enclosures, significantly reducing total system cost and installation complexity. Featuring quick-plug technology and a modular stackable form, the eForce system allows for rapid installation with reduced labor and fewer wiring errors. Backed by a standard 15-year industry-leading warranty, with an optional 30-year extension available — offering unmatched long-term value and peace of mind. With an IP65 rating and built-in heating elements, eForce is engineered to perform in extreme temperatures and weather conditions, indoors or out. The streamlined enclosure supports a clean aesthetic and meets NEC and NFPA standards — enabling flexible installation with minimal visual and space impact. Scale your system vertically up to 28.8 kWh per stack or expand laterally up to 268.8 kWh total, adapting to evolving residential or commercial energy needs. Approved for Virtual Power Plant (VPP) programs nationwide, enabling customers to earn revenue and support grid reliability with intelligent energy discharge.
