Fortress Power eForce 19.2kWh 400Ah LFP Battery System

Product Description
The Fortress Power eForce 19.2kWh Battery System combines two stackable 9.6kWh LFP battery modules to provide 400Ah of energy storage for whole-home backup, off-grid living, solar self-consumption, light commercial applications, and DIY solar projects.
The included eForce eWay provides centralized wire management with integrated busbars, conduit ports, an emergency shutoff, and LED indicators. A battery combiner, battery cables, wire-management components, and floor-mount base are also included for a clean, organized installation.
This battery system can be paired with a compatible Envy inverter, sold separately, to create an integrated IP65-rated energy storage system.
- 19.2kWh total capacity: Two eForce 9.6kWh LFP battery modules provide 400Ah of energy storage.
- Long-lasting LFP technology: The battery modules provide more than 8,000 cycles and have a 20-year design life.
- Cable-free stacking: Quick-connect plugs allow the two modules to stack vertically without battery cables between them.
- Integrated eWay: Combines busbars, conduit ports, an emergency shutoff, and LED indicators in one wire-management system.
- Essential components included: Comes with a battery combiner, battery cables, wire management, and floor-mount base.
- Built-in heating: Integrated battery heaters help maintain performance in cold conditions.
- Indoor or outdoor installation: The IP65-rated design supports year-round operation indoors or outdoors.
- Expandable energy storage: Additional battery capacity can be added vertically or laterally as energy needs grow.
- Mobile monitoring: Compatible with the Fortress Power mobile app for system monitoring and energy management.
- Code-compliant design: Engineered to meet NEC and NFPA standards.
- Warranty coverage: Eligible for a maximum 15-year warranty when paired with an Envy inverter.
