Selecting a home battery system is a major decision. You need reliable performance, long-term durability, and a solution that aligns with your energy goals.
Fortress Power simplifies the process. Specializing in advanced LFP energy storage, we offer two high-performance 48V battery families built to cover the full range of residential and light commercial needs:
- eForce — maximum-capacity system engineered for whole-home and commercial-grade backup.
- eBoost — high-value, modular system designed for everyday reliability and scalability.
Both systems deliver long cycle life, industry-leading safety, and seamless installation through the fully integrated Fortress Power eWay wireway. Below is a complete breakdown to help you determine which solution best fits your home or project.
eForce vs. eBoost: Understanding the Two Fortress Power Battery Lines
eForce: Premium Backup Power for Full-Home & Commercial Loads
The eForce is engineered for homeowners and businesses that require maximum capacity and robust resilience. With up to 28.8 kWh in a single unit and 12 kW of continuous output, eForce supports high-demand homes, critical loads, and small commercial applications without needing multiple batteries.

When paired with the Envy inverter and Guardian Gateway, eForce qualifies for an extended warranty of up to 15 years, providing long-term confidence and protection. Best for:
- Whole-home backup
- Light commercial applications
- High-demand electrical loads
- Installations requiring fewer batteries per inverter
- Customers seeking premium longevity and warranty coverage
eBoost: A High-Value, Modular Solution for Everyday Home Storage
The eBoost is designed for homeowners who want a cost-effective, flexible battery system without compromising performance. Its 16.1 kWh capacity and 12.8 kW output cover the needs of most households, and additional units can be added as usage grows.

Like eForce, eBoost utilizes the integrated eWay system, which keeps wiring clean, speeds up installation, and ensures code-compliant deployment. Best for:
- Homeowners seeking an affordable entry point into storage
- Modular energy expansion over time
- Daily cycling applications
- Residential backup power
- Straightforward, efficient installations
Important Note About eWay Compatibility
The eBoost uses its own dedicated eWay wireway. While it shares the same integrated design philosophy as eForce, the eBoost eWay is not cross-compatible with the eForce eWay. Each battery line requires its corresponding eWay model to ensure proper fit, optimized installation, and system safety. Installers should always pair each battery series with its designated eWay configuration.
eForce vs. eBoost: Understanding the Two Fortress Power Battery Lines
Both Fortress Power battery lines feature the integrated eWay, a streamlined wireway system that consolidates:
- Busbars
- Conduit ports
- Breakers & emergency shutoff
- Communications wiring
- Clean cable routing
The eWay eliminates clutter, reduces installation time, and provides a consistent, professional appearance across all Fortress Power systems. For installers, this translates to faster commissioning and fewer external components — helping keep projects efficient and code-compliant.
How Fortress Power Compares: eBoost & eForce vs. Competitors
