Residential Backup Power Project: A 5.12kWh Wall-Mounted LiFePO4 Battery Solution
Project Overview
A residential energy storage inquiry focused on finding a reliable battery solution for household backup power during grid outages.
The prospective buyer was interested in a 5.12kWh wall-mounted lithium battery designed to support essential household electricity needs when the main power supply is unavailable.
Based on this requirement, Shenzhen Hongyi Technology Co., Ltd. recommended a 51.2V 100Ah LiFePO4 home energy storage battery. The proposed solution was selected for its wall-mounted design, expandable capacity options, and integrated battery protection functions.
Project Status: Product recommendation and quotation provided. Purchase intent expressed; order not yet confirmed.
Customer Requirements: Reliable Backup Power for Residential Use
Power interruptions can affect essential household activities, particularly when refrigeration, lighting, communication equipment, and other daily electrical appliances depend on a stable electricity supply.
During the inquiry, the buyer expressed interest in a home battery backup solution that could help maintain basic household electricity during outages.
The main requirements included:
-
Residential Backup Power: A battery solution intended to support essential household loads during grid interruptions.
-
Suitable Storage Capacity: A 5.12kWh battery as the initial product preference.
-
Space-Saving Installation: A wall-mounted design to reduce the need for additional floor space.
-
Future Expansion: The ability to connect compatible battery units in parallel when greater storage capacity is required.
-
Battery Protection: Built-in protection functions to support safe battery operation.
Rather than recommending a complete energy storage system before understanding the installation requirements, we first focused on the battery specification that matched the buyer's initial preference.
Our Proposed Solution: 5.12kWh Wall-Mounted LiFePO4 Battery
After reviewing the inquiry, we recommended a 51.2V 100Ah wall-mounted LiFePO4 battery with a nominal energy capacity of 5.12kWh.
LiFePO4 battery technology is widely used in residential energy storage because of its thermal stability and long cycle-life potential. For this project, the selected battery also offers a compact wall-mounted configuration and support for parallel expansion.
Key Product Features
1. LiFePO4 Battery Technology
The battery uses lithium iron phosphate chemistry, providing a stable battery platform for residential energy storage applications.
2. 5.12kWh Storage Capacity
With a rated capacity of 100Ah and nominal voltage of 51.2V, the battery provides 5.12kWh of nominal energy storage.
3. Wall-Mounted Design
The wall-mounted configuration helps save floor space and provides an alternative installation option for residential energy storage projects.
4. Parallel Expansion Capability
Compatible battery units can be connected in parallel to increase total storage capacity as household energy requirements change, subject to system compatibility and installation requirements.
5. Battery Protection Functions
The battery incorporates protection functions covering overcharge, over-discharge, and overcurrent conditions to support controlled operation.

Project Communication and Support
To help the buyer evaluate the proposed battery, our team provided product information and a quotation based on the initial requirements.
The communication covered several important aspects:
-
Product Recommendation: Introduced the 5.12kWh wall-mounted LiFePO4 battery.
-
Technical Information: Shared the product specifications, battery configuration, and main functions.
-
Capacity Consideration: Discussed the initial storage capacity preference for residential backup power.
-
Quotation Support: Provided product images, technical documentation, and pricing information.
The final backup system configuration still requires confirmation of the household load, inverter output requirements, and expected backup duration.
A 5.12kWh battery does not automatically guarantee whole-home backup. Actual performance depends on the connected loads, inverter compatibility, and available usable battery energy.
