The eForce 19.2 kWh Battery System
The Fortress Power eForce 19.2 kWh consists of two stacked battery modules delivering double the capacity in a unified system. This configuration uses the same tier-1 prismatic LFP cells rated for 8,000 cycles and maintains the 20-year design life across both modules. The two-module stack connects through quick-plug technology for simplified installation.
With 19.2 kWh of nominal energy and 250A maximum charge/discharge capability, this configuration suits whole-home energy storage applications. The system can expand to 28.8 kWh with an additional module or scale horizontally by paralleling up to 8 two-module stacks for 153.6 kWh total capacity. All configurations maintain IP65 weather protection and operate from -4°F to 140°F.
eForce 19.2 kWh Battery System Features
- Enhanced Power Delivery: 250A maximum charge and discharge current with 240A/250A closed-loop operation supports higher power demands.
- Two-Module Stack: Pre-configured dual battery system with 2×200Ah nominal capacity connected via quick-plug technology.
- Dual Thermal Management: Each module includes integrated heaters for consistent performance across the full -4°F to 140°F operating range.
- Surge Power Capability: Maintains 14,400W surge discharge power for 10 seconds to handle motor starts and peak loads.
- Continued Expansion: Add one more module vertically or parallel up to 8 stacks for system capacities up to 153.6 kWh.
eForce Series Flexible Expansion Options
The eForce 19.2 kWh two-module configuration offers multiple growth paths:
- Add one module vertically to reach 28.8 kWh maximum stack height
- Parallel up to 8 two-module stacks for 153.6 kWh total capacity
- Maintain single-point monitoring and control for all connected batteries
Fortress Power eForce 19.2 kWh Battery System Review
The eForce 19.2 kWh configuration doubles the capacity while maintaining the same footprint and installation simplicity. The two-module stack arrives pre-configured with quick-plug connections, reducing field assembly time. At 250A maximum discharge, this system provides increased power handling capability suitable for whole-home backup applications including high-draw appliances.
The closed-loop charge/discharge rates of 240A/250A enable sophisticated energy management strategies and faster charging from solar or grid sources. The ability to add a third module or parallel multiple stacks ensures the system can grow with changing household needs. With the same 8,000-cycle rating and 10-year warranty as the single module, this configuration delivers reliable long-term performance.
