CFE-5 Home Energy Storage Battery, Home Energy Storage System, home solar battery, household energy storage, home power backup battery, Low Voltage LFP Battery
The CFE-5 is a high-performance Home Energy Storage System designed for modern households and small commercial applications. Built with safe and reliable Lithium Iron Phosphate (LiFePO4) cells, it provides a total energy capacity of 5.12kWh, usable energy of 4.4kWh, and continuous discharge power of 5.0kW. Operating at a nominal voltage of 51.2V, the system is compatible with mainstream low-voltage inverters and is well suited for residential solar and backup power applications.
Its modular design supports parallel connection of up to 8 units, allowing total capacity to expand beyond 40kWh as energy demand grows. The CFE-5 integrates a smart BMS, OTA online upgrades, and multiple communication interfaces to deliver a safer, more reliable, and more intelligent solution for household energy storage. Whether used for daily solar self-consumption or emergency backup, it offers homeowners flexible and efficient energy management.
The CFE-5 uses highly stable LiFePO4 chemistry, offering excellent thermal stability and strong safety performance. Under standard conditions, cycle life exceeds 6,000 cycles at 80% DoD, helping reduce replacement frequency and long-term ownership cost. Backed by a 5-year warranty, it provides dependable long-term value for residential users.
The system supports parallel connection of up to 8 units, enabling flexible capacity expansion from 5.12kWh to over 40kWh. Its tool-free quick-mount design helps reduce installation time and labor cost, making it easier for installers and users to deploy the system efficiently. For customers seeking a compact alternative to a Floor-Mounted Energy Storage Battery, the CFE-5 offers flexible installation options for different home environments.
The built-in Wi-Fi module allows users to monitor system status and energy data remotely through a mobile app. With OTA online updates, the system can continuously optimize performance and improve user experience over time, making it a practical and intelligent home solar battery solution.
High-precision voltage and current sampling technology helps ensure more stable and accurate State of Charge (SoC) estimation. This reduces the risk of inaccurate battery level readings and helps improve daily operating reliability.
The CFE-5 supports CAN and RS485 communication and is compatible with mainstream inverter brands including Luxpower, Solis, Deye, Victron, and Growatt. This broad compatibility makes it easier to integrate into both new and existing residential PV systems.
The system features a durable metal housing with an IP20 protection rating and a clean white finish. With dimensions of 442 × 450 × 133 mm and a weight of 42kg, it supports cabinet, wall-mounted, and floor-standing installation, adapting to a wide range of indoor residential settings. As a practical Low Voltage LFP Battery, it combines compact size with reliable power output.
Paired with rooftop PV systems, the CFE-5 stores excess solar energy generated during the day for use at night, improving self-consumption rates and reducing dependence on the utility grid. This makes it an efficient home solar battery for modern residential energy use.
During grid outages, the system can provide reliable backup power for essential household loads such as refrigerators, lighting, routers, and security devices. As a dependable home power backup battery, it helps maintain daily comfort and energy security.
The CFE-5 is also suitable for convenience stores, small offices, studios, and similar sites that require stable emergency power support to maintain basic operations during outages.
For RVs, vacation cabins, and small off-grid properties, the CFE-5 can serve as the core battery storage unit when paired with solar panels, supporting greater energy independence and flexible power use.
The battery can charge during low-cost off-peak periods and discharge during peak-rate hours, helping users optimize electricity consumption and lower power bills.
The CFE-5 has obtained CE and CB certifications, meeting relevant safety and performance requirements for the EU and major international markets. It has also passed the UN38.3 transportation safety test, ensuring safe global logistics and shipment.
CFE follows a strict ISO quality management system, and the product undergoes rigorous testing from cell level to system level to ensure reliable quality, safety, and long-term performance.
