[0002] As the global energy structure undergoes profound changes and renewable energy technologies advance rapidly, household energy storage systems are becoming increasingly prominent as a vital bridge connecting homes to green energy. These systems not only represent a core trend in future home energy management but also serve as a key tool for achieving energy self-sufficiency and improving household energy efficiency. They cleverly capture and store electricity from renewable energy sources such as solar panels and wind turbines, providing a green and sustainable solution for daily household electricity needs. Crucially, in the event of an emergency power outage, household energy storage systems can quickly switch to emergency power, ensuring continuous power supply to critical household loads, greatly enhancing the safety and reliability of household electricity use.

[0003] However, despite the enormous potential and value of household energy storage systems, traditional designs face numerous challenges. The installation process is cumbersome and complex, often requiring specialized teams to work for a long time. This not only increases costs but also prolongs the wait time for users to enjoy convenient services. Furthermore, the system's subsequent operation and maintenance is equally challenging, requiring regular professional maintenance to ensure long-term stable operation. Furthermore, low energy storage efficiency and insufficient battery protection levels are two major bottlenecks hindering the development of traditional household energy storage systems. Inefficient energy storage means wasted energy, while batteries with low protection levels are easily affected by environmental factors, posing safety risks.

[0004] Therefore, in response to the growing demand of modern families for efficient, safe and convenient energy storage, it is particularly urgent to develop a new type of household energy storage system. Utility Model Content
