Fortress Power | High Voltage Smart Energy Storage System 11.4kW
Fortress Power Avalon – High Voltage Smart Energy Storage System (11.4kW)
The Fortress Power Avalon is a revolutionary 11.4kW high voltage smart energy storage system designed to deliver unmatched performance, modular flexibility, and true energy independence. Purpose-built for both residential and commercial settings, Avalon combines a high-capacity LiFePO4 battery, hybrid inverter, and a Smart Energy Panel (SEP) into one seamless, all-in-one solution that automatically manages your energy flow across multiple power sources.
Key Features:
-
11.4kW Output Capacity – Delivers powerful, high-voltage energy for large homes, light commercial sites, or heavy-load applications.
-
All-in-One Design – Includes battery modules, hybrid inverter, and SEP to manage power distribution across grid, solar, generator, and backup circuits.
-
Smart Energy Panel with Load Shedding – Supports up to 12 single-phase or 6 split-phase loads. Provides critical load functionality without requiring a dedicated load panel—no need to rewire your main electrical panel.
-
Flexible & Modular Architecture – Lightweight, stackable battery modules and components (each under 100 lbs) make transport and installation simple.
-
Remote Placement Support – Avalon’s battery, inverter, and SEP can be installed separately, even tens or hundreds of feet apart, offering maximum flexibility in layout.
-
Advanced LiFePO4 Battery Chemistry – Safer, longer-lasting (6,000+ cycles), and more efficient than traditional lead-acid systems.
-
Seamless Energy Management – SEP acts as the central hub for dynamic power control, optimizing energy use from multiple inputs (solar, grid, generator) and outputs (home loads, critical circuits).
