In recent years, accelerated global energy transition, rising electricity prices, and grid instability have driven rapid expansion of residential storage and small commercial & industrial (C&I) storage markets in regions including Europe, North America, Australia, and Japan. Households and small-to-medium enterprises are increasingly deploying smart energy storage systems to achieve energy savings, reduce costs, and enhance power resilience.

According to data from the International Energy Agency (IEA), global residential storage installations grew by over 65% year-on-year in 2023. Germany, California (U.S.), Australia, and Japan have emerged as key growth markets, primarily driven by policy support, high electricity prices, and increased adoption of renewable energy. In Europe, Germany leads the residential storage market. Government subsidies for "solar PV + storage" systems, rising household electricity and grid fees have reduced system payback periods to 6–8 years. Italy, the Netherlands, Belgium, and other countries have also introduced tax incentives and subsidies to encourage distributed energy storage development. The European Union's "Fit for 55" initiative, targeting a 42.5% share of renewables by 2030, will further stimulate storage demand.

North America's market is growing rapidly. The U.S. Inflation Reduction Act (IRA) offers investment tax credits (ITC) of up to 30%, with energy storage systems eligible for independent applications, significantly lowering adoption barriers. In high-electricity-cost and frequently blacked-out regions such as California and Texas, residential storage has become standard in new housing developments. In 2023, U.S. residential storage installations surged over 90% year-on-year, with annual growth projected to remain above 30% over the next five years.

The Asia-Pacific region is equally dynamic. With rooftop solar penetration exceeding 30%, Australia leverages storage to enable "daytime charging and nighttime usage," effectively reducing grid dependency. In Japan, frequent earthquakes and power shortages have prompted strong government promotion of "community microgrids combined with home energy storage," widely adopted by small businesses and retail stores.

Small C&I storage holds significant potential. Facing high demand charges and substantial peak-to-off-peak price differentials, supermarkets, clinics, and small factories utilize energy storage for load shifting and peak shaving to substantially reduce operational costs. For example, after installing a 50 kWh storage system, a mid-sized restaurant chain in Hawaii (U.S.) saved $12,000 annually on electricity bills. In the UK, some commercial users also generate additional revenue by participating in grid ancillary services.

Technological advancements are accelerating market adoption. Intelligent energy management systems (EMS), modular designs, and long-life lithium batteries have made systems more efficient, easier to install, and scalable. Integrated plug-and-play solutions significantly lower the barrier to entry.

Looking ahead, declining battery costs, increasing grid stress, and advancing carbon neutrality goals position overseas residential and small C&I energy storage markets for potential doubling in size over the next five years. For users pursuing energy independence, cost optimization, and sustainability, smart energy storage has evolved from an "optional" solution to an "essential" one.
