【Chemical Machinery and Equipment Network Industry News】In 2022, the spreading global energy crisis will further intensify under the conflict between Russia and Ukraine, and European energy costs and electricity prices will rise year by year, making the boom of household photovoltaic distribution and storage continue to heat up, and the demand for household energy storage will continue to rise, becoming a new track
for the new energy industry.

Household energy storage, also known as home energy storage system, is similar to a micro-energy storage power station, and its operation is not affected
by the pressure of urban power supply.
During low hours, the battery pack in household energy storage can be charged by itself for backup peak power peak or power failure
.

Household energy storage adopts the integrated microgrid design concept, which can operate in off-grid and grid-connected dual modes, and can realize seamless switching of operation modes, greatly improving power supply reliability
.
In addition, the household energy storage configuration flexible and efficient management system, which can adjust the operation strategy according to the power grid, load, energy storage and electricity price to optimize the system operation and maximize
user benefits.

On the whole, household energy storage is exquisite and beautiful, easy to install, equipped with long-life lithium-ion batteries, and combined with photovoltaics, can provide power demand
for residences, public facilities, small factories, etc.
According to different coupling methods and whether they are integrated into the power grid, household energy storage can be mainly divided into four types
: hybrid home photovoltaic + energy storage system, coupled household photovoltaic + energy storage system, off-grid household photovoltaic + energy storage system, and photovoltaic energy storage energy management system.

At present, the global residential energy storage incremental market is mainly concentrated in Europe and the United States represented by Germany and the United States, and its growth is driven by policy support, household photovoltaic installed capacity and energy storage penetration rate increase
.
HIS Markit data shows that in 2020, global household energy storage is mainly concentrated in Germany, Italy, the United Kingdom, as well as Japan, Australia, the United States, etc.
, of which Germany, the United States, Japan and Australia accounted for a total of 74.
8%.

According to 2021 data, in the household energy storage market, Tesla accounted for 15% of the global household energy storage market with its outstanding product strength and brand effect, followed by the Chinese enterprise Pineng Technology, accounting for 13%.

In addition, domestic manufacturers such as Penghui Energy, Haichen Energy Storage, Sungrow, Deye Co.
, Ltd.
, Jinlang Technology, Goodway, Sunwoda, Hekang New Energy and Shouhang New Energy are also accelerating the layout of overseas markets
.

Generally speaking, a complete set of household energy storage includes the cost of photovoltaic, energy storage inverter, energy storage battery and other components, the core of which is energy storage battery and energy storage inverter
.
In 2021, the average hardware cost of household energy storage will be about 2.
8 yuan/Wh, and it is estimated that the household energy storage market size will be about 111.
7 billion yuan in 2025
, calculated by the average annual cost reduction of 5% of energy storage systems.

Since the beginning of this year, the demand for energy storage equipment in Europe has increased
significantly.
In order to ensure market supply, China's energy storage industry chain has also responded
quickly.
Customs statistics show that in the first half of this year, the number of lithium-ion batteries exported by China increased by 36.
8% year-on-year, and the export volume of inverters increased by 576.
7%
year-on-year.
At present, the shortage of small-capacity batteries for household energy storage continues to be in short supply, and photovoltaic inverter manufacturers have successfully shipped energy storage inverter products through the original channels, and the price and profit have maintained a high level, and household energy storage products have become an important performance growth point
in the future.

It is worth noting that household energy storage can realize the integrated design of home appliances and provide power demand
for smart homes.
Industry insiders believe that household energy storage is expected to become an important strategic home appliance product in the world, China's energy storage battery and inverter companies have outstanding products, cost reduction, channels and other capabilities to respond to this industrial trend, it is expected that the industry will maintain rapid growth until 2025, high electricity prices and low penetration rate is the core driving force
.

Further, when the demand for components and equipment such as energy storage batteries and energy storage inverters increases with the household energy storage market, the demand for energy storage BMS, IGBT, power chips, AC/DC inverters, DC/AC converters, etc.
will also rise
.
It is understood that at present, MPS, Silan Micro, Xinjieneng and other semiconductor companies are making efforts
in various market segments.
