A Compact 5.12kWh Battery for Practical Home Energy Storage
This 51.2V/48V 100Ah LiFePO4 battery is designed for users who need a compact and reliable battery pack for solar energy storage and backup power. Its 5.12kWh nominal energy capacity can help store solar energy during the day and supply power during evening use, power outages or peak electricity periods.
The wall mounted cabinet helps save floor space and keeps the installation area clean and organized. With a maximum size of 450 × 440 × 153mm excluding terminals and handle, and a weight of about 42kg, the battery is suitable for homes, utility rooms, garages, equipment rooms, telecom cabinets and small off-grid power systems.
Built with 3.2V 100Ah LiFePO4 Cells
The wall mounted battery pack uses 100Ah 3.2V LiFePO4 cells and is assembled in a 16S1P configuration to create a 51.2V nominal battery system. The cell design supports stable operation, high current capability and reliable performance for energy storage applications.
At cell level, the nominal capacity is 100Ah, the minimum capacity is 98Ah and the nominal voltage is 3.2V. Each cell has an internal impedance of ≤2mΩ under the specified test condition. At pack level, the assembled battery capacity is ≥98Ah under 0.2C standard discharge.
This design makes the battery suitable for low-voltage solar energy systems that require a balance of usable energy, compact structure and stable battery chemistry.
Standard CC-CV Charging for Reliable Battery Operation
The battery pack uses a CC-CV charging method. Under standard charging conditions, it is charged with 20A constant current and 58.4V constant voltage until the charging current declines to ≤0.01C. This charging method helps the battery reach full charge in a controlled and stable way.
The recommended pack charge voltage is 58.4V ±0.02V. The maximum continuous charge current is 100A, while the standard charge current is 20A. For real projects, the charging setting should be matched with the inverter, charger, cable specification, breaker selection and BMS protection design.
100A Continuous Discharge for Essential Backup Loads
At battery pack level, this 51.2V/48V 100Ah LiFePO4 battery supports up to 100A maximum continuous discharge current. With a nominal voltage of 51.2V, the battery can provide approximately 5.12kW class output under suitable system design.
This makes it suitable for essential household backup loads, solar self-consumption systems, telecom power backup, monitoring equipment, lighting, network equipment, small appliances and low-voltage energy storage projects. The actual output power should always be matched with the inverter rating, cable design, breaker protection and local installation requirements.
Bluetooth and WiFi Monitoring for Smarter Daily Control
The battery supports Bluetooth and WiFi monitoring, making daily battery management more convenient. Users can check battery data through a mobile device and monitor the system more easily during normal operation. This helps improve user experience for home solar storage, backup power and small energy storage systems.
Bluetooth and WiFi monitoring are especially useful for daily operation and remote-style checking. Users and installers can view battery information more conveniently, including battery status, state of charge, voltage, current, operating condition and alarm reminders.
Touchscreen Display for On-Site Battery Checking
The battery is designed with a touchscreen display, allowing installers and users to check key battery information directly on the unit. During installation, commissioning and maintenance, the screen can help show important operating data such as battery status, voltage, current, state of charge, alarm information and basic system condition.
Up to 16 Units in Parallel for Flexible Capacity Expansion
For projects that need larger storage capacity, this 51.2V/48V 100Ah 5.12kWh wall mounted LiFePO4 battery supports up to 16 units in parallel. A single battery provides 5.12kWh nominal energy, while a 16-unit system can expand to about 81.92kWh nominal energy.
CAN, RS485 and RS232 Communication for Inverter Integration
This 51.2V/48V 100Ah wall mounted battery supports CAN, RS485 and RS232 communication. These communication ports help the battery exchange operating data with compatible low-voltage inverters, making the system easier to manage during charging, discharging and protection control.
Wall Mounted Cabinet and Product Dimensions
The compact wall mounted cabinet is designed for installations where floor space is limited. With a maximum thickness of 153mm, maximum width of 440mm and maximum height of 450mm excluding terminals and handle, the battery can fit into many home energy storage and small equipment room layouts.
The cabinet design should be installed on a suitable wall structure according to local installation requirements. The installation area should be dry, ventilated, protected from direct water exposure and away from fire, sharp objects, strong mechanical shock and conductive materials that may cause short circuit risk.
Working Temperature and Storage Guidance
The battery pack is designed for charging from 0°C to 45°C and discharging from -20°C to 60°C under the specified operating humidity range. This makes it suitable for indoor and sheltered energy storage locations such as garages, utility rooms, equipment rooms and solar storage areas.
For long-term storage, the battery should be stored in a suitable indoor environment and charged to about 30% to 50% capacity. The specification recommends charging the battery about once every half year to prevent over-discharge. For battery packs with protection circuit, charging every three months during storage is recommended.
Suitable for Home Solar Storage, Backup Power and Small Energy Projects
This 48V wall mounted solar battery is perfect for daily home use from apartments and townhouses to larger family homes. It keeps your essential loads running during outages such as lights WiFi router fridge and key appliances while also helping you store excess solar for use at night. By shifting more of your consumption to your own clean energy you reduce reliance on the grid lower electricity bills and enjoy a more comfortable secure home every day.
