Residential energy storage systems are gradually entering thousands of households, and why are household energy storage batteries becoming increasingly popular?

Residential energy storage refers to the use of renewable energy sources such as solar energy and wind energy by households to store excess electrical energy and supply it to the household when needed. Currently, the most common residential energy storage system utilizes solar panels to generate electricity and store excess energy in batteries. On sunny days, solar energy can be fully utilized to charge the batteries and store excess energy. Then, during the night or on cloudy days, households can draw power from the batteries for use.

At the same time, residential energy storage batteries also have significant advantages, including:

1. Price Reduction: The cost of photovoltaic energy storage systems has decreased over the past few years, enabling more households to afford this technology. Additionally, photovoltaic energy storage systems have become more economically viable.

2. Popularization of Renewable Energy: With the increasing utilization of renewable energy like solar energy, the demand for residential energy storage batteries has also risen. Residential energy storage allows for the storage of solar energy collected during the day, to be used during periods of low sunlight, thereby enhancing energy utilization efficiency.

3. Energy Cost Savings: Through residential energy storage batteries, households can store electricity during periods of low electricity prices and use it during peak hours when prices are high, thereby further reducing their energy expenses.

4. Increased Electricity Convenience: Residential energy storage batteries can provide backup power, ensuring that households can maintain basic electricity usage during power outages, thereby safeguarding normal household operations. Furthermore, residential energy storage batteries can also be used to charge electric vehicles, enhancing the multifunctional utilization of residential energy.

5. Promoting Energy Transition: The widespread adoption of residential energy storage batteries has driven the development of distributed energy systems, reducing reliance on traditional energy sources and promoting sustainable energy development and environmental protection. Residential energy storage batteries offer a better choice and solution for energy transition.

6. Ensuring Stable Energy Supply: Photovoltaic energy storage systems can store solar power, enabling households to maintain basic energy supply even during power outages or energy shortages. This provides households with a more reliable and stable energy supply.

Energy storage is a crucial prerequisite for the large-scale development and utilization of new energy sources, serving as essential infrastructure for establishing a new power system dominated by renewable energy. In recent years, the installed capacity of energy storage has been continuously expanding. Among them, lithium-ion energy storage, with its advantages of fast charging and discharging, high comprehensive efficiency, strong technological practicality, and few limiting factors, has accounted for a significant proportion in recent installations, becoming the mainstay of energy storage. Residential energy storage systems are moving towards scale and popularization, with vast market prospects anticipated in the future.
