New white paper reveals global residential energy storage system market reached 38.1 GWh in 2025

PRESS RELEASE

WENZHOU, China, 28 July 2026 – The global residential energy storage system market reached 38.1 GWh in 2025, according to the white paper The Global Residential Energy Storage System Market (2026), jointly released by Fox ESS and independent international consulting firm Frost & Sullivan. The report estimates a 54.6% CAGR from 2021 to 2025 and projects growth to 128.7 GWh by 2030, sustaining a 27.3% CAGR over 2026–2030.

The white paper ranks Fox ESS as No. 1 in 2025 residential energy storage system shipments, reporting a 10.5% market share and outperforming other major players in the sector. Earlier this year, Fox ESS was also recognised as No. 1 in the residential energy storage market by S&P Global Energy. The company provides integrated PV–storage–charging–heat solutions, supported by locally delivered service capabilities around the world.

“The residential energy storage market has transitioned from policy-driven demonstration projects to commercially viable, mainstream adoption,” said Michael Zhu, CEO of Fox ESS. “Our No. 1 position reflects not only product performance, but also our commitment to building local partnerships and service networks, so homeowners can achieve real energy independence.”

Key trends shaping the residential storage landscape

The report identifies four major trajectories driving the next phase of residential storage adoption:

• – Higher integration and modular design: Battery, PCS, BMS and EMS components are increasingly being combined into integrated systems. This reduces installation complexity while improving safety. Fox ESS’s product portfolio reflects this trend through integrated solutions spanning hybrid inverters, battery systems, EV chargers, and heat pumps.
• – Digitalisation and intelligent control: Energy Management Systems (EMS), alongside cloud platforms and AI-driven algorithms, are turning storage systems into full energy management platforms. Fox ESS’s smart platform, FoxCloud 2.0, integrates AI capabilities to support remote monitoring, predictive maintenance, and optimised dispatch strategies.
• – Broader application beyond the home: While residential use remains central, storage technology is expanding into commercial and industrial (C&I) deployments, microgrids, data centres, and virtual power plants (VPPs), helping unlock additional revenue streams.
• – Global scale with deeper local execution: Competition is shifting from simply exporting products to delivering value through global operations. Increasingly, success depends on securing regional certifications, building distribution networks and establishing local service capacity. Fox ESS has expanded its presence accordingly, with offices and service teams in Germany, the UK, Italy, Poland, Australia and other countries.

Broader market momentum continues

The report also notes that the wider global energy storage system market, covering utility-scale and commercial segments, grew even faster, expanding from 26.9 GWh in 2021 to 419.7 GWh in 2025 (a 98.8% CAGR). It is forecast to reach 1,507.5 GWh by 2030, supported by a 25.4% CAGR over 2026–2030.

As the energy transition accelerates, residential energy storage is set to move from an optional backup to a core element of home energy infrastructure. The companies best positioned to capture long-term value will be those that combine technical innovation, local delivery, and ecosystem partnerships.
