Before exploring the home storage in detail, let's take a look at the development history of the Residential Energy Storage System (ESS):

As early as 50 of the last century, in the 1960s, the US Department of Energy launched a Residential Energy Storage System project, led by the Sandia National Laboratory to carry out research on how to reserve nuclear energy. By the 1970s, due to a serious oil crisis in the United States, the research focus of Sandia Lab was converted to replace the renewable energy that can replace oil. By the 1980s, the US Department of Energy further expanded the Sandia laboratory research project -while creating renewable energy, it explored battery development and test projects. Since then, Sandia Lab has undertaken the exploration of energy storage projects. However, the concept of energy storage at that time was still at the national level and did not involve commercial or civilian use.

In 1991, the project was upgraded to the power storage project of the power grid, and at the same time, it began to do some power storage facilities for commercial use. The international lead-zinc organization and power research institutions were also participated during this period. By 1996, the Residential Energy Storage System had begun to take shape and began to expand to commercial and civilian use.

In terms of strategic opportunities of family energy storage, Europe and the United States are currently leading the country. They demand for photovoltaic penetration and power stability in households is more advanced. Therefore, the market for overseas family energy storage is more mature than domestic. At present, this is also this is also this. Huaxu Electric, a brand of priority expansion.
