CFE-PS4 All-in-One Mobile Power Station, 3kW Energy Storage Power Supply, 4kWh LiFePO4 Battery, Home Backup Power, Small Business Uninterruptible Power Supply
The CFE-PS4 is a highly efficient integrated energy storage system designed for home backup, small business continuity, and flexible mobile power applications. Combining a high-performance inverter, smart charger, MPPT solar charge controller, and a built-in 4.0kWh Lithium Phosphate Battery into a single compact unit, it offers a practical and reliable power solution for users who need clean, quiet, and uninterrupted electricity.
With 3kVA / 3kW pure sine wave AC output, the CFE-PS4 is well suited for powering essential household appliances, office equipment, shop systems, and temporary loads. It supports multiple charging methods, including utility grid, generator, and solar PV, giving users greater flexibility in different operating environments. During a power outage, the system automatically switches to battery mode in less than 10ms, ensuring continuous power for critical loads.
Its floor-standing, all-in-one structure allows fast deployment without complicated rewiring, making it an excellent alternative to traditional fuel generators. For customers looking for a clean and practical backup solution, the PS4 offers the convenience of a Portable Solar Power Station while delivering the stability and functionality of a fixed all in one home energy storage system.
The CFE-PS4 integrates a 3kW inverter, MPPT solar charge controller, charger, and 4.0kWh battery into one compact enclosure. This simplified architecture reduces installation time, eliminates the need for multiple external devices, and improves overall user convenience. As a hybrid all in one energy storage system, it helps installers and end users achieve faster setup and cleaner system integration.
Unlike conventional fuel generators, the PS4 produces no exhaust fumes, no fuel smell, and almost no operating noise. It is suitable for indoor or semi-indoor deployment where clean energy and low maintenance are important. This makes it an ideal replacement for a traditional generator in homes, offices, shops, and temporary-use locations.
The system supports charging from a 230V utility grid, external generator, and solar PV input up to 3.5kW, with an MPPT voltage range of 60–430V. This flexible charging capability helps ensure the battery can be replenished in a variety of energy scenarios, improving system availability and resilience.
The built-in Lithium Phosphate Battery uses safe and stable LFP chemistry, offering up to 8,000 cycles for long-term use. A smart multi-level BMS continuously protects the system against over-voltage, over-current, short circuit, and over-temperature, helping maintain safe and stable performance.
With UPS-level transfer time of less than 10ms, the PS4 ensures seamless switching during outages. It is suitable for powering sensitive loads such as refrigerators, Wi-Fi routers, POS systems, computers, lighting, and communication devices, helping users avoid interruptions in daily life and business operations.
The PS4 can be connected directly between the utility and critical loads without major modification to existing building wiring. It also supports RS-485 communication and optional Wi-Fi connectivity for convenient monitoring and remote management.
During a grid outage, the PS4 can automatically supply power to essential household appliances such as refrigerators, lighting, routers, and televisions. It is a practical backup solution for families that need stable electricity for daily life.
The system helps maintain continuous operation of POS machines, security systems, refrigerated cabinets, and lighting during power cuts, reducing downtime and protecting business continuity.
For users working from home, the PS4 provides reliable backup for computers, monitors, internet equipment, and communication devices, helping ensure online meetings and work tasks continue without disruption.
The unit can also serve as a clean power source for camping, outdoor booths, mobile food operations, and temporary events. For this kind of flexible use case, it functions similarly to a Solar Camping Generator, while offering greater system stability and longer battery life than many conventional portable products.
When paired with rooftop solar panels, the PS4 stores excess daytime solar energy for use at night or during cloudy periods. This helps improve solar utilization and supports a more efficient residential energy setup, especially for users seeking a compact all in one home energy storage system.
The CFE-PS4 has obtained multiple international certifications, including CE, RoHS, SAA, FCC, and PSE, demonstrating compliance with major safety and electromagnetic compatibility requirements in Europe, Australia, the United States, and Japan.
The battery system also meets UN38.3 transportation safety requirements, ensuring safe and compliant global logistics. CFE follows strict quality management procedures and conducts rigorous testing from cell selection to final assembly to ensure consistent reliability, safety, and performance.
