The customized home energy storage battery system mainly refers to the energy storage system installed on the house. Its operating methods include independent operation, renewable energy power generation equipment and household heat storage equipment for independent operation, with small wind power generation units, roof photovoltaic power generation equipment and household heat storage equipment. The application of customized home energy storage battery systems includes: electricity management, electricity rate control (low charging high); power supply reliability; distributed renewable energy access; electric vehicle energy storage battery application, etc.

The customized home energy storage battery market is an emerging market, and there are not many global demonstration projects. Some companies are developing home energy storage products that should be concentrated in Germany, the United States and Japan. As a largest photovoltaic power generation country in Germany, new energy has been widely used in Germany; Japan is a special market and test site in the early family energy storage market; the US community energy storage market has developed for many years, and there are some important demonstration projects. But the development speed of the home energy storage market is not as good as Germany and Japan. The Chinese family energy storage market has just begun, and its development is still facing many constraints. However, domestic companies have also been involved in the home energy storage system market and developed a lithium battery energy storage system for domestic and foreign energy storage markets.

Compared with lead -acid batteries, customized home energy storage batteries have the advantages of small size, light weight, strong temperature adaptability, high charging and discharge efficiency, safe and stable, long service life, and energy saving and environmental protection.
