Athena Wall-Mounted Battery Value Series 15kWh (51.2V/300Ah)
Model: SCAE-B-51.2-300

Product Overview
Is the SCAE-B-51.2-300 the Right Capacity for You?
Best suited for
The Athena B Value Series 51.2V 300Ah provides 15kWh in a 48.5 by 26 by 77 centimeter wall enclosure, extending wall-mounted storage toward large homes and long-outage regions at a value price.
Typical loads this capacity handles
Paired with a compatible 48V inverter it sustains fridge, lighting, entertainment, communications, and typical household loads for well over a full night; the 200A discharge gives about 10kW of DC-side headroom.
Estimated runtime
Runtime example: about 13.5kWh usable. A 500W load lasts roughly 27 hours and a 1000W load around 13 to 14 hours, giving one to two days of normal essentials without recharge.
Sizing advice
Pick the B 300Ah for long-duration backup in a wall format where floor-standing systems cannot fit, and confirm the wall can carry the larger, heavier enclosure. The Value Series targets cost-sensitive large-capacity projects with standard feature needs.

How long can the Athena Wall-Mounted Battery Value Series 15kWh (51.2V/300Ah) power my home during an outage?
The Athena Wall-Mounted Battery Value Series 15kWh (51.2V/300Ah) provides 15,360Wh of stored energy (approximately 13,824Wh usable at 90% depth of discharge). At an average essential-load draw of 500W (lights, router, refrigerator, and TV), it can sustain power for approximately 27.6 hours. At 1,000W, runtime is approximately 13.8 hours. Actual runtime depends on total connected load and usage patterns.
How is the wall-mounted battery installed?
The Athena Wall-Mounted Battery Value Series 15kWh (51.2V/300Ah) features a compact wall-mounted design suitable for garages, utility rooms, and indoor installations. It mounts to a solid wall using the included wall bracket and hardware. The 51.2V LiFePO4 battery connects to a compatible hybrid inverter via the included communication cables. Professional installation by a certified electrician is recommended. The wall-mounted form factor saves floor space compared to floor-standing cabinets.
How long does the LiFePO4 battery last?
The LiFePO4 cells in the Athena Wall-Mounted Battery Value Series 15kWh (51.2V/300Ah) are rated for 2,000-4,000 charge-discharge cycles before capacity drops to 80% of the original rating. In a typical daily-cycle residential application, this translates to 5-10 years of service life. LiFePO4 chemistry also offers superior thermal stability and safety compared to lead-acid or NMC batteries, with no maintenance required.
