The A1.1 PTPW-B 48V 51.2V 100Ah Wall-Mounted Lithium Energy Storage Battery is designed as a reliable, space‑saving power solution for modern home solar systems. With a nominal voltage of 51.2V and a capacity of 100Ah, it provides approximately 5.12 kWh of usable energy, making it suitable for daily residential consumption, backup power, and peak‑shaving applications.This wall‑mounted battery adopts advanced lithium iron phosphate (LiFePO₄) cells, known for their long cycle life, high safety, and excellent thermal stability. Compared with traditional lead‑acid batteries, it offers higher energy density, lighter weight, and significantly longer service life, reducing maintenance and replacement costs over time. The chemistry and mechanical design are optimized to withstand frequent charge‑discharge cycles associated with solar applications.An integrated battery management system (BMS) continuously monitors cell voltage, temperature, and current to ensure safe and efficient operation. The BMS provides protection against overcharge, over‑discharge, over‑current, and short circuit, and supports temperature protection for both charging and discharging. This helps maintain battery health, enhances reliability, and improves overall system performance. Real‑time monitoring and diagnostic functions can be accessed via compatible inverters or communication interfaces.The product features a compact, wall‑mounted design that saves floor space and allows flexible installation in homes, garages, or utility rooms. Its robust metal housing and sleek, minimalist appearance are suitable for residential environments while protecting internal components from dust and accidental impact. The enclosure is typically rated for indoor or semi‑indoor use, with consideration for ventilation and thermal management to ensure stable performance.The A1.1 PTPW-B battery is compatible with a wide range of 48V hybrid and off‑grid inverters, enabling seamless integration into existing or new solar photovoltaic systems. It supports common communication protocols such as CAN or RS485 (depending on configuration), allowing intelligent interaction with the inverter for optimized charging, discharging, and load management. This interoperability helps the system automatically prioritize solar energy, battery storage, and grid power according to user‑defined settings.In practical use, the battery can store surplus solar energy generated during the day and deliver it during peak demand periods or at night, helping households reduce dependence on the grid and lower electricity bills. In regions with unstable power supply, it can serve as a backup power source, providing continuous energy to critical loads such as lighting, communication devices, refrigeration, and home office equipment.Overall, the A1.1 PTPW-B 48V 51.2V 100Ah Wall-Mounted Lithium Energy Storage Battery offers a safe, durable, and efficient solution for residential solar energy storage. Its combination of LiFePO₄ technology, intelligent BMS, compact wall‑mount design, and broad inverter compatibility makes it a strong choice for homeowners seeking to improve energy independence and enhance the reliability of their solar power systems.
