Langhorne, PA - October 16, 2025: Fortress Power, a leading provider of advanced battery energy storage solutions, proudly announces the release of the eBoost, a powerful and efficient new energy storage system engineered for both grid-tied and off-grid applications. Designed with installers and homeowners in mind, the eBoost delivers more power for less cost through a simplified design that streamlines installation and maximizes system performance.

Each 16kWh unit provides sustainable, long-term backup power for homes and businesses—reducing reliance on the grid and helping users save on electricity costs while maintaining peace of mind during outages. Its modular design allows systems to expand up to 256kWh by connecting 16 units in parallel, providing flexibility for growing energy needs.

The eBoost combines the durability and intelligence Fortress Power is known for with features that make installation faster, maintenance easier, and operation more efficient. With locking wheels for easy maneuvering, an IP65-rated enclosure, and internal heating elements, it performs reliably in extreme weather conditions—from -4 ºF to 140 ºF—ensuring dependable performance year-round.

"The eBoost sets a new standard for flexible, high-capacity energy storage," said Matthew Daniel, Product Manager for eBoost at Fortress Power. "Its scalability, durability, and seamless integration with the Envy Duo 21 inverter make it an ideal choice for installers and customers who demand reliable performance with ease of deployment."

Thanks to its powerful BMS, a single eBoost module can deliver up to 12 kW of continuous charge and discharge power, allowing customers to start with a single unit and expand the system as needed.

Key Features of the eBoost:
• 16kWh per unit, expandable up to 256kWh (16 units in parallel)
• Simplified, installer-friendly design for fast deployment
• Larger capacity cells deliver higher power density while reducing space requirements
• Locking wheels for safe and effortless mobility
• IP65-rated enclosure with internal heating for dependable performance (-4 ºF to 140 ºF)
• Integrated eWay Wireway System for neat and efficient connectivity
• Seamless integration with Fortress Power Envy Duo 21 inverter
• 10-year warranty for long-term reliability

"Since 2016, Fortress Power has been driven by a mission to make our energy storage systems easier to install, more efficient, and more cost-effective," added Daniel. "The eBoost represents that vision—combining engineering simplicity with the power and resilience our customers expect."

Supporting both single-phase and three-phase 208V commercial applications, the eBoost is built for adaptability. It is also the next generation of battery storage following Fortress Power's successful eVault MAX—offering greater energy density, reduced weight, and a smaller footprint. Designed for indoor or outdoor installation, the eBoost leverages Fortress Power's eWay interconnection system to simplify setup while maintaining a clean, professional appearance.
The eBoost redefines modern energy storage—providing homeowners, businesses, and installers with a system that is smarter, stronger, and more sustainable.
