Home energy storage devices store electrical energy for use when needed -- also known as electric energy storage products or "battery energy storage systems" (BESS), hereafter referred to as home storage. The core component of the home storage is a rechargeable battery, usually lithium-ion or lead-acid. The other component is the inverter, which can intelligently control the charge and discharge control system. With energy storage in the average home, we can implement the concept of distributed generation, which eases the strain on the grid and reduces the use of fossil fuels, as a necessary decentralization to achieve carbon neutrality or zero neutrality. Before going into more detail, let's take a look at the history of energy storage systems (ESS) : Back in the 1950s and 1960s, the Department of Energy's Energy Storage Systems Program, led by Sandia National Laboratories, looked at how to store nuclear energy. In the 1970s, as the United States faced a severe oil crisis, Sandia LABS shifted its focus to renewable energy sources that could replace oil. By the 1980s, the U.S. Department of Energy had expanded the Sandia LABS research program to explore battery development and testing projects while creating renewable energy sources. Sandia LABS has since taken on the energy storage project. But the idea of energy storage at the time was national, not commercial or residential.

Sandia LABS has since taken on the energy storage project. But the idea of energy storage at the time was national, not commercial or residential. In 1991, the project was upgraded to a grid battery storage project, and some tests for commercial electric storage facilities were also started. During this period, the international lead-zinc organization and electric power research institutions also participated in the research. By 1996, energy storage systems were taking shape and expanding to commercial and civilian use. In terms of strategic opportunities for home energy storage, Europe and the United States are ahead of China at present. Their demand for household photovoltaic penetration and power stability is more advanced. Therefore, the overseas home energy storage market is more mature than the domestic market.
At the national level: Overcoming transmission losses: Transmission losses from power stations to households are inevitable, especially in densely populated metropolises where power stations cannot be built in and transmission losses are greater. However, if households are encouraged to generate and store electricity independently and reduce external transmission, transmission losses can be greatly reduced and transmission efficiency of the grid can be realized. Power grid support: household energy storage If it is connected to the power grid and the surplus electricity generated by the household is input to the power grid, the pressure on the power grid can be greatly alleviated: 1) The power supply response can be provided during peak hours to reduce the use of inefficient diesel power generation; 2) Use a power frequency that matches the local power grid, such as 50Hz or 60Hz. Reducing the use of fossil fuels: Households storing their own electricity can greatly improve the efficiency of electricity generation, while the use of fossil fuels such as natural gas, coal, oil and diesel will be phased out.
At the household level: reduce energy expenditure: the household generates and stores electricity independently, which can greatly reduce the power consumption of the grid.
Avoid peak pricing: Energy storage batteries can store electricity during low peak periods and discharge it during peak periods. Realize electricity independence: households store solar power during the day and use it at night, and can also be used as backup power supply in case of sudden power failure.
