Fortress Power eForce Stackable 9.6kWh LFP Battery

Product Description
The Fortress Power eForce Stackable 9.6kWh LFP Battery is a modular energy storage solution designed for whole-home backup, off-grid living, solar self-consumption, light commercial systems, and DIY solar installations.
Each 9.6kWh battery module can be stacked vertically in configurations of up to three modules. The system can also be expanded laterally, allowing homeowners to increase their energy storage as their needs grow.
The integrated eWay wireway combines busbars, conduit ports, an emergency shutoff, and LED indicators in one organized hub. Pair the eForce with an Envy inverter, sold separately, to create a streamlined IP65-rated energy tower with integrated AC and DC wiring.
- Long-lasting LFP battery: Provides more than 8,000 cycles with a 20-year design life.
- Expandable energy storage: Stack as many as three battery modules vertically or expand the system laterally.
- Cable-free stacking: Wireless quick-connect plugs allow vertically stacked modules to connect without cables.
- Integrated eWay wireway: Combines busbars, conduit ports, an emergency shutoff, and LED indicators in one hub.
- Built-in battery heater: Helps maintain battery performance in cold climates.
- Indoor or outdoor installation: The IP65-rated design supports reliable year-round operation.
- Simplified inverter integration: The Envy inverter mounts directly to the eWay for a clean energy tower configuration.
- System monitoring: Compatible with the Fortress Power mobile app for monitoring and energy management.
- Code-compliant design: Engineered to meet NEC and NFPA standards.
- Grid participation: Supports intelligent energy discharge through grid-participation programs.
- Extended warranty coverage: Includes a standard 15-year warranty with an optional 30-year extension.
