Fortress Power eForce 19.2kWh Battery | Stackable Outdoor Storage | Scalable to 153.6kWh | Whole-Home & Commercial Backup

Outdoor-Ready Power. Built for Performance.

The Fortress Power eForce 19.2kWh is a robust, high-capacity lithium iron phosphate (LFP) battery solution engineered for whole-home backup, off-grid living, and scalable commercial storage. Combining two vertically stacked 9.6kWh modules with the integrated eWay cabling platform, the eForce 19.2 offers 19.2kWh of usable energy in a compact, weatherproof design—perfect for outdoor installations and space-conscious energy projects.

With support for up to 8 units in parallel (up to 153.6kWh), smart communication protocols, and surge discharge up to 14,400W, the eForce 19.2 is a powerful, flexible storage system designed to meet the demands of modern energy independence.

Key Features:

High-Capacity, Stackable Storage: Each system delivers 19.2kWh of usable energy by stacking two 9.6kWh LFP modules—scale up to 153.6kWh with 8 units in parallel for larger homes or commercial systems.
Surge Power When You Need It: Provides up to 14,400W of surge power for 10 seconds, ideal for motor starts, HVAC systems, and other high-demand loads.
Advanced LFP Chemistry: Tier-1 prismatic lithium iron phosphate cells ensure thermal safety, long cycle life (8,000+ cycles at 70% end-of-life), and high reliability in demanding environments.
Integrated eWay Cabling Platform: Comes equipped with Fortress Power’s eWay, simplifying AC/DC cabling and housing a lockable, taggable power disconnect and internal busbar for clean, code-compliant installations.
Smart System Communication: Supports RS485, CAN, and Wi-Fi for seamless closed-loop communication with Fortress Envy inverters and other compatible 48V systems—ensuring efficient charging, discharging, and diagnostics.
Outdoor-Rated & Climate Resilient: Fully IP65-rated and equipped with built-in heating elements, the eForce 19.2 is engineered to withstand extreme climates and deliver reliable performance in all seasons.
Flexible Mounting Options: Supports ground, wall-mount (with optional accessory), or floor-standing configurations, offering maximum flexibility for diverse installation environments.

Power Storage & Inverter

Item / Appliance	Typical Power (W)	Usage Time (hrs)	Total Energy Needed (Wh)	Battery Size Needed (Ah) (12V System)	Inverter Size Needed (W)
LED Light Bulb (10W)	10W	5 hrs	50 Wh	4.2 Ah	100W
Phone Charging	5–10W	2 hrs	10–20 Wh	0.8–1.7 Ah	100W
Laptop Charging	50–100W	3 hrs	150–300 Wh	12.5–25 Ah	200W
Ceiling Fan	75W	6 hrs	450 Wh	37.5 Ah	150W
LED TV (32")	60W	4 hrs	240 Wh	20 Ah	150–200W
Refrigerator (Mini)	100W (avg)	8 hrs	800 Wh	66.6 Ah	300–500W

Key Formulas

Purpose	Formula	Example
Energy Consumption (Wh)	`Watts × Hours`	60W × 4 hrs = 240 Wh
Battery Capacity (Ah)	`Watt-hours ÷ System Voltage (V)`	240 Wh ÷ 12V = 20 Ah
Inverter Size (W)	`Total Watts × 1.25 (for safety margin)`	300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W)	`Sum of all appliance watts to be used at once`	Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery	`(Battery Ah × Voltage) ÷ Total Load (W)`	(100Ah × 12V) ÷ 240W = 5 hrs

How To Choose The Right Products

Need / Application	Recommended Battery	Inverter Size	Notes
Basic lighting + phone charging	50Ah – 100Ah (12V)	100W–200W	For small backup setups
Home office (laptop, fan, TV)	150Ah – 200Ah (12V or 24V)	500W – 1000W	For moderate usage with 4–6 hours of backup
Home backup (fridge, lights)	200Ah+ (24V or 48V recommended)	1000W – 1500W	Ideal for longer backups or heavier loads
Business / shop power backup	300Ah+ (48V system)	2000W – 3000W	Suitable for commercial setups or extended power outages
