Lithium Battery for Home Backup

Introduction

 

The 51.2 V lithium battery for home backup uses high-quality LiFePO₄ cells, providing 10.24 kWh nominal capacity and 9.216 kWh of usable energy. Designed for long-term reliability and safety, it delivers over 6,000 cycles at 90% DOD. Its compact design is suitable for residential backup power.

Chemistry & Materials

Constructed with high‑grade LiFePO₄ cells featuring ≤5 mΩ internal resistance, ensuring excellent thermal stability, low risk of thermal runaway, extended cycle life, and minimal maintenance over long-term residential or small-scale commercial use.

Voltage & Capacity

Nominal voltage of 48 V with a rated capacity of ~4,800 Wh and usable energy ~4,320 Wh. Supports continuous charge/discharge currents up to 50 A, with short-term peak currents reaching 100 A, suitable for standard household loads and short-term surge demands.

Smart System Control

Integrated Battery Management System (BMS) with RS485, CAN, and Bluetooth interfaces continuously monitors cell voltage, temperature, current, and state-of-charge. Provides real-time alerts, balancing, and data logging to optimize system performance and lifespan.

Cycle Life & Reliability

Rated for more than 6,000 full cycles at 80 % depth-of-discharge under 25 ± 5 °C conditions. Maintains stable capacity retention over years of residential operation, ensuring dependable and predictable energy storage.

Environmental Design

Operational temperature range of 0 °C to 40 °C, storage range -20 °C to 70 °C, and humidity tolerance of 10 %–80 % RH. Designed to maintain performance in typical home or small commercial environments.

Installation & Integration

Compact, wall-mountable or floor-placement design with modular connectivity for easy series or parallel expansion. Compatible with mainstream inverters and EMS platforms, supporting flexible energy system configurations.

Ideal for residential solar-plus-storage systems, home backup power, and smart energy management. The modular design allows flexible scaling for single-family homes or larger residential setups, integrating easily with common inverters and energy management systems.
