Home energy storage system, also known as household energy storage, is a kind of energy storage system used in a family or residential environment. It mainly stores electricity for daily use or for use when needed, similar to a miniature energy storage power station. It can also be used in conjunction with renewable energy systems such as solar photovoltaic panels or wind turbines: the system converts electricity into direct current (DC) to be stored in batteries and then converted to alternating current (AC) for use in the home when needed. Benefits: Provides back-up power in case of sudden power outages, balances energy supply and demand, increases self-sufficiency, and reduces electricity bills. With the development of technology and cost reduction, household storage is becoming more and more popular.
Home Inverter System
Household storage mainly consists of three parts: energy storage inverter, energy storage battery, and temperature control system. It is usually installed indoors, so the requirements for safety will be higher. The inverter is not very different, but with the growth of the industry, the demand is exploding. Household storage small energy storage battery, the kernel integration technology requirements are not high. Because it is a direct to C product, brand reputation and channel management, user customization and after-sales service is the core competitiveness. Temperature control is also an indispensable part of the energy storage equipment in the work process will generate heat, but also by the external environmental temperature. Too high will lead to equipment performance degradation, shortened life or even damage, too low will also have a negative impact on the performance and efficiency of the equipment. The goal of energy storage temperature control is to maintain energy storage equipment operating within the appropriate temperature range through rational temperature management, improving system efficiency and reliability.
Continuously rising energy and electricity prices have driven the rapid adoption of household storage, which has suddenly exploded in the global market.
Europe has an early layout in the energy transition and is at the forefront of market development progress. Overseas geopolitical conflicts in recent years have led to unstable energy supply and persistently high fluctuations in electricity prices. 2022 Distributed photovoltaic paired with household storage for home power solutions has been developing at a high rate. Germany as the main European energy storage construction countries, the construction of household storage provides strong policy support. Europe's top five: Germany, Italy, Austria, the United Kingdom and Switzerland, accounting for 88% of Europe, of which Germany leads with 59% share.
The European market for photovoltaic, energy storage products, trade barriers are far lower than the U.S. market, and the local dealers of overseas brand acceptance is higher, Chinese companies with their own product strength in the European market is performing well. Distribution channels are still mainly controlled by local enterprises, Chinese batteries abroad still need to cooperate with local enterprises.

The U.S. power system is relatively decentralized, many operators, divided into regions, the overall coordination capacity is poor, low risk resistance, encountered unexpected weather, power outages are difficult to avoid. In recent years, large-scale energy storage construction layout more, the scale of the world's leading, but household storage construction accounted for a relatively low proportion. IRA program released to increase subsidies, the household storage play a stimulating role, mainly from the demand for distributed power generation. Highly concentrated in economically developed states with liberal policies and relatively high prices. California occupies half of the market, and Hawaii is geographically small but has a very high penetration rate, basically completing full coverage of household storage. Another stimulus comes from the high price of electricity after inflation, under the double stimulus, household storage development accelerated.
The U.S. PV and energy storage market is relatively closed, and it is difficult for Chinese companies to enter the new energy field. The enactment of the 301, 201 bill set high barriers, so the way to participate in the local market is more limited. The household storage market can only be accessed through the supply chain of local energy storage companies.
In Africa, Southeast Asia, the Middle East and other regions, due to poor grid infrastructure, unstable power supply, and the inconvenience of using electricity in off-grid places such as islands, etc., there is an immediate need for electricity preparation, and the household storage market is rapidly rising. Especially in South Africa, a large African country, power shortages and power restrictions are very serious, and power cuts sometimes last up to 10 hours. This is done to prevent the accelerated collapse of aging coal-fired power plants, leading to paralysis of the entire power system. The government, in order to alleviate the power crisis and reduce the use of electricity by residents, announced an increase in national electricity prices and introduced relevant incentives and subsidies. So the immediate need for household storage plus policy and location advantages (South Africa is the world's highest proportion of renewable energy generation), household storage development prospects.

At present, South Africa mainly rely on diesel generators and household light storage two ways to cooperate with the realization of self-generated electricity for self-consumption. Diesel generator early investment is small, but the late maintenance cost is high, not environmental protection; Household light storage early investment is slightly larger, but more environmentally friendly, warranty time is longer. Household storage demand stems from the power of the people's livelihood such as the impact of the immediate needs of end-customers more in pursuit of the ultimate cost-effective, the market is about to enter a period of rapid development.
