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.
