Household battery energy storage + refrigerator may be applied in the same way as air conditioner + photovoltaic, but it will not become a product that most people can use.
Batteries + refrigerator
Recently, the solution of household energy storage + refrigerator has become a new topic, Some home appliance manufacturers have begun to study the application of battery energy storage technology to refrigerators.
If the refrigerator encounters unexpected situations such as power outages, it can ensure that food will be kept fresh for a week. Therefore, some people think that the global market for home energy storage will be very broad in the future.
Refrigerator plus battery energy storage, is it a good business ?
Some manufacturers launched a photovoltaic (energy storage) DC inverter air conditioning system in 2021. Simply put, it is solar + lithium batteries + air conditioning, which is essentially a distributed photovoltaic storage system. This system can only be used on large-scale commercial clients such as data centers, and it is difficult to enter the home scene in the short term.
Compared with distributed power stations, using refrigerators + battery energy storage for households is more of an imagination. At least in the Chinese market, solar storage systems are not needed in most household scenarios.
Difficulties
Home energy storage is actually not a new concept. In 2013, there were companies manufacturing user energy storage systems, including portable energy storage, home energy storage and so on.
Generally, household energy storage can be divided into on-and off-grid systems, and there are also hybrid systems that integrate on-and off-grid systems.
Europe, US, Japan & Australia
Home energy storage systems are a very mature industry, with GW-level shipments overseas, and Europe, the United States, Japan and Australia account for three-quarters of the usage. Especially in Germany and the United States, where new energy is valued, household energy storage will reach more than 1GW in 2020.
Government subsidies are indispensable behind household energy storage in Europe and the United States. In 2018, the U.S. policy gave 26% tax credits to users of solar battery power storage systems. In Europe, the Austrian government will subsidize 12 million euros for household energy storage between 2020 and 2023.
Users in Europe, the United States, and Japan have real needs for household photovoltaic energy storage systems. In the absence of major incidents, an average of 1.5 hours of power outages occur each year.
If you live in an area with frequent severe weather, you may experience power outages for more than 10 hours a year.
In areas with vast land, sparsely populated areas and outdated equipment, home energy storage systems are essential. Similarly, Japan, where frequent earthquakes will cause power outages, will also deploy home energy storage systems.
