The 51.2V 200Ah Wall-mount LiFePO4 Battery is a high-capacity, space-saving energy storage solution designed for large residential homes, small commercial buildings (like offices or retail stores), and off-grid properties that require significant energy reserves without occupying floor space. With a nominal voltage of 51.2V and a 200Ah capacity, it provides an impressive total energy output of 10.24kWh (51.2V × 200Ah = 10240Wh = 10.24kWh)—enough to power a large home (with appliances like refrigerators, washing machines, and HVAC systems) for 1 to 2 days during a power outage, or store excess solar energy for use during peak demand hours.

Its wall-mounted design is a key advantage, as it can be installed on exterior walls (with weatherproof models) or interior walls (like garage or utility room walls), eliminating the need for floor space. This is particularly useful for homes or small businesses with limited storage area, where a floor-standing battery would be impractical. The mounting system is robust, with heavy-duty brackets that can support the battery’s weight (typically 60 to 70 kg)—though it is still lighter than lead-acid batteries of similar capacity (which can weigh over 150 kg), making installation easier. The casing is often made from durable, weather-resistant materials (for outdoor models) or fire-retardant plastic (for indoor use), protecting the battery from the elements and physical damage.

LiFePO4 chemistry ensures long life and safety. This battery has 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. It also has a low self-discharge rate (less than 3% per month), so it retains energy for long periods when not in use—ideal for backup power systems that may sit idle for months between outages. Safety features include overcharge protection, over-discharge protection, short-circuit protection, and thermal protection, all managed by the built-in BMS. The BMS also balances individual cell voltages, ensuring consistent performance and preventing premature battery failure.

Performance is outstanding, with a discharge rate of 1C to 2C—allowing it to power high-demand appliances like electric stoves or HVAC systems without voltage drops. For solar users, it efficiently stores excess energy generated during the day, reducing reliance on the grid and maximizing savings on electricity bills. It also supports smart integration with home energy management systems, allowing users to monitor SoC, energy usage, and charging schedules via a mobile app. Many models also offer backup mode, automatically switching to battery power within milliseconds of a grid outage—ensuring no interruption to critical appliances.

Compatibility is extensive, working with most 51.2V solar inverters (including hybrid inverters that combine solar and grid power) and charge controllers. 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, off-grid power. For users needing a high-capacity, space-saving energy storage solution for their home or small business, the 51.2V 200Ah Wall-mount LiFePO4 Battery offers the perfect balance of power, durability, and convenience.
