As the global energy transition accelerates, the demand for photovoltaic energy storage batteries and household large-capacity, high-power batteries is growing rapidly. Especially driven by the "dual carbon" goals, household photovoltaic + energy storage systems have become a popular choice for improving energy independence and economy.

Drivers of growth in the residential energy storage market

First, the rise in electricity prices and the widening gap between peak and valley electricity prices have increased users’ demand for the economic efficiency of energy storage systems. Households can store electricity when prices are low and use it during peak hours or sell it back to the grid, thereby reducing their electricity bills. Secondly, the instability of photovoltaic power generation has prompted the development of household energy storage systems to increase electricity self-sufficiency and reduce dependence on the power grid.

The trend of large-capacity and high-power batteries

With the increasing intelligence of household appliances and the increase in electricity demand, traditional small-scale energy storage solutions can no longer meet the demand. Large-capacity (above 16 kWh) and high-power (above 15 kW) batteries have become mainstream to support high-power devices such as electric vehicle charging, heat pumps, air conditioners, etc. In addition, the improved safety of technologies such as lithium iron phosphate batteries makes the household energy storage market more attractive.

Future Outlook

In the future, the household energy storage market will continue to grow driven by policies, technology and economics. Battery systems with higher energy density, faster charging and discharging, and more intelligence will become mainstream, helping home energy management enter a new stage.

On the other hand, although the strict US product certification system (such as UL, IEC, NEC, etc.) has increased the certification costs and cycles of companies, it has helped export companies improve product quality and enhance global competitiveness. By obtaining authoritative certification, companies can not only enter the US market, but also improve their brand reputation and expand their business globally.
