Why Choose the Fortress Power eForce 28.8 kWh?

Are you looking for a high‑capacity storage system that delivers whole‑home backup, strong scalability, and dependable performance in challenging conditions? The Fortress Power eForce 28.8 kWh is designed to help you achieve robust energy independence and resilience. Whether you’re a homeowner wanting extended backup during outages or a solar installer designing large‑scale hybrid systems, this battery stack gives you a powerful, future‑proof solution.

Key Features

• Stacked Modular Design (3 × 9.6 kWh): Combines three battery modules in a vertical stack, giving 28.8 kWh nominal energy while maintaining a compact footprint.

• Long Cycle Life & Safe Chemistry: Uses automotive‑grade lithium‑iron phosphate (LFP) cells rated for 8,000 cycles at 70% depth of discharge, delivering long service life and high safety.

• All‑Weather Durability: IP65 rated enclosure with built‑in heating ensures reliable performance in extreme temperatures (from −20 °C to +60 °C).

• High Power Capability: Supports nominal charge/discharge current up to 250A, surge power for high inrush loads, and operates in both open‑loop and closed‑loop configurations without performance loss.

• Integrated Communications & Monitoring: Equipped with RS485, WiFi, CAN interfaces; includes real‑time status LEDs and connects via Fortress Power’s eWay for wiring, busbars, disconnects, etc.

• Scalability: Allows stacking up to three modules per stack (28.8 kWh per stack), and you can parallel multiple stacks (up to 5 stacks in typical setups) for larger system capacities.

Versatile Applications

Ideal for:

• Homes needing extended backup power for whole‑home or high load appliances.

• Hybrid solar + storage systems where scaling later is part of the plan.

• Installations in harsh climates needing rugged batteries that can handle outdoor exposure.

• Systems with high startup loads (motors, pumps, AC units) needing strong discharge/surge capacity.

• Residential or light commercial installations where monitoring, safety, and code compliance matter.
