This fall, Fortress Power introduces two new innovations within its 48V lineup: the eBoost Scalable Energy Storage System and the Envy Duo 21 Hybrid Inverter. Together, they form a dynamic duo designed to deliver more power and greater system flexibility—while lowering installation time and overall project costs.
For homeowners, businesses, and installers alike, this pairing represents a smarter way to design energy systems that grow with your needs.
eBoost: Scalable, Reliable Energy Storage
The Fortress Power eBoost is a 16kWh stackable LFP battery built for whole-home backup, off-grid living, and light commercial applications. With scalability, durability, and seamless integration at its core, the eBoost makes dependable energy storage simple.
Key Highlights:
- 16kWh capacity per module – designed for higher load demands
- Expandable to 256kWh – connect up to 16 units in parallel
- Integrated eWay Wireway system – faster, code-compliant installs
- IP65-rated with internal heaters – reliable all-weather performance
- Modular design – reduces install time and labor
- Whole-home compatibility – engineered to pair with the Envy Duo 21
The result? A system that’s as easy to expand as it is to install, without sacrificing long-term performance.
Envy Duo 21: The Hybrid Inverter with More Flexibility
The Envy Duo 21 is Fortress Power’s most versatile 48V hybrid inverter, engineered for high-performance residential and light commercial projects. With its robust PV input and parallel scalability, it’s built to handle today’s demanding energy applications.
- Up to 25kW PV input capacity
- 12kW continuous / 16kW peak output
- Parallel up to 10 units for 120kW total power
- Built-in AC/DC breakers and rapid shutdown transmitter
- Remote monitoring and firmware updates via the Fortress Power mobile app
- Dual-phase operation – 240V split-phase or 208V three-phase (minimum of 2 inverters for 3-phase)
By combining flexibility with advanced monitoring, the Envy Duo 21 gives installers and system owners full control over their energy.
