Fortress Power eBoost 16 kWh LFP Battery + eWay Cable Management System | Modular Energy Storage & Integrated Wireway Solution
High Capacity. Clean BOS Integration. Built for Real-World Installs.
The Fortress Power eBoost 16 kWh LFP Battery with eWay Cable Management System is a high-capacity, weatherproof energy storage solution designed for residential and light-commercial ESS applications. Each eBoost battery delivers 16 kWh of usable LiFePO₄ (LFP) energy, while the eWay wireway ecosystem provides a clean, protected, and code-compliant AC/DC connection to Fortress Envy series inverters.
With IP65-rated construction, internal heating, and integrated busbar-based wiring, the eBoost system is engineered for harsh climates, fast installations, and scalable deployments—supporting up to 16 units in parallel for large-capacity energy storage systems.
System Overview
-
Large Usable Capacity: Each eBoost cabinet delivers 16 kWh of usable energy, ideal for high-load homes, EV-ready installations, and space-constrained projects.
-
Scalable Architecture: Parallel up to 16 units per system. A 32 kWh variant is available for larger builds, supporting up to 512 kWh per site depending on configuration.
-
Integrated eWay Cable Management: The eWay and eWay Lite wire management systems provide a dedicated, UL-compliant pathway for both AC and DC conductors, eliminating external raceways and simplifying balance-of-system (BOS) integration.
