3kW 5kWh Integrated Residential Battery Backup Energy Storage System – Application Scenarios

This 3kW 5kWh all-in-one residential battery backup energy storage system seamlessly integrates high-performance BYD lithium iron phosphate batteries with pure sine wave inverters, offering a comprehensive energy solution. Its exceptional performance, convenient portability, and dual functionality for grid-connected and off-grid operation make it an ideal choice for meeting the energy needs of modern households and various settings. The following are its primary application scenarios:

  • Home Energy Independence and Security: As the core energy management system for a household, this all-in-one unit efficiently collects and stores solar power, providing stable, clean power output for the entire home when needed. Whether optimizing energy use during peak consumption periods or addressing sudden power outages, it ensures the continuous operation of appliances such as refrigerators, air conditioners, lighting, and televisions, significantly reducing reliance on the traditional grid and effectively cutting electricity costs.

Home load power supply

  • Remote Areas and Regions with Unstable Power Supply: In areas with insufficient grid coverage, unstable power supply, or frequent power outages, this system can establish a completely independent microgrid. By converting clean energy into usable electricity through solar charging, it completely resolves power supply challenges, providing users with reliable, uninterrupted power supply and greatly enhancing the convenience of daily life and work.
  • Emergency backup power: In emergencies such as natural disasters (e.g., earthquakes, floods), extreme weather (e.g., blizzards, typhoons), or grid failures, the system can be quickly activated to provide reliable backup power. Its 10-millisecond UPS switching time ensures seamless operation of critical equipment (e.g., medical devices, communication systems, security monitoring), safeguarding life and property safety.
  • Outdoor Activities and Mobile Applications: This all-in-one unit features a compact design with wheels for easy mobility. This makes it an ideal choice for outdoor camping, RV travel, fieldwork, temporary events, or emergency rescue scenarios. Users can easily transport it to any location requiring power, providing convenient electrical support for lighting, cooking, entertainment devices, and more.

  • Power supply for basements, garages, and specific areas: For specific areas in the home that require continuous power supply, such as basements, garages, storage rooms, or refrigerators that need to maintain low temperatures, this system provides stable power supply to prevent damage to items or inconvenience caused by power outages.
  • Smart energy management and maximized economic benefits: The system supports grid charging and photovoltaic charging and has the capability to feed power back into the grid. Users can charge from the grid during off-peak hours based on electricity pricing policies, use stored power during peak hours, or sell excess power back to the grid, achieving intelligent energy scheduling and maximized economic benefits.

All in one solar energy storage

  • Protection for Equipment with High Power Quality Requirements: The built-in pure sine wave inverter outputs high-quality power identical to grid power, ensuring compatibility and protection for sensitive electronic devices such as computers, precision instruments, audio equipment, and medical devices. This effectively prevents damage caused by power fluctuations and extends the lifespan of the equipment.
  • Environmental protection and sustainable development: Combined with solar power generation, this system utilizes clean, renewable solar energy to reduce reliance on traditional fossil fuels, lower carbon emissions, and contribute to environmental protection. Additionally, with a cycle life of over 5,000 cycles and a 5-year warranty, the system ensures long-term stable operation and economic benefits.
