The 51.2V 200Ah Wall mounted LiFePO4 Battery is a high-capacity, space-saving energy storage solution tailored for large residential homes, small commercial buildings (like retail stores or offices), and off-grid properties where floor space is at a premium. With a nominal voltage of 51.2V (typical for 16-cell LiFePO4 packs) and a 200Ah capacity, it delivers an impressive 10.24kWh of total energy (51.2V × 200Ah = 10240Wh)—enough to power a large home with essential appliances (refrigerators, washing machines, HVAC systems) for 1 to 2 days during a grid outage, or store excess solar energy for use during peak demand hours when electricity rates are highest.

Its wall-mounted design is a game-changer for space-constrained environments. It can be installed on interior walls (garages, utility rooms) or exterior walls (with weatherproof models), eliminating the need for floor space that would otherwise be occupied by a bulky standalone battery. The included mounting hardware simplifies installation, and at 60 to 70 kg, it is significantly lighter than lead-acid batteries of similar capacity (which can weigh over 150 kg), making it easier for homeowners or small business owners to handle. The casing is constructed from durable, fire-retardant plastic (for indoor use) or weather-resistant materials (for outdoor installation), protecting against dust, moisture, and physical damage.

LiFePO4 chemistry ensures exceptional longevity and safety. It offers a cycle life of 3000 to 5000 cycles at 80% DoD, meaning it can last 10 to 15 years in residential use—far longer than lead-acid batteries (which typically last 3 to 5 years). It also has a low self-discharge rate (less than 3% per month), so it retains energy for extended periods when not in use—ideal for backup systems that may sit idle for months between outages. The built-in BMS is critical for safety, monitoring cell health, preventing overcharging/over-discharging, and balancing cell voltages to maintain consistent performance. It also includes thermal protection, shutting down the battery if temperatures exceed safe limits.

Performance-wise, the battery delivers steady power even under high loads. It supports a discharge rate of 1C to 2C, allowing it to power energy-hungry appliances like electric stoves or central AC units without voltage drops. For solar users, it efficiently stores excess energy generated during the day, reducing reliance on the grid and lowering electricity bills. Many models also integrate with home energy management systems (HEMS), enabling users to monitor SoC, energy usage, and charging schedules via a smartphone app. Additionally, it features rapid backup switching, transitioning to battery power within milliseconds of a grid outage to avoid interruptions to critical devices.

Compatibility is extensive, working with most 51.2V solar inverters (including hybrid inverters) and charge controllers from top brands like SMA, Victron Energy, and Growatt. It is also suitable for off-grid applications, such as remote cabins or vacation homes, where it can be paired with a large solar panel array to provide reliable, independent power. For users seeking a high-capacity, space-efficient energy storage solution that balances performance and safety, this wall-mounted battery is an excellent choice.
