According to Fortune Business Insights, the U.S. Residential Lithium-ion Battery Energy Storage System Market size was valued at USD 1,520.00 million in 2024 and is projected to grow from USD 1,991.09 million in 2025 to USD 5,092.26 million by 2032, exhibiting a CAGR of 14.36% during the forecast period from 2025 to 2032. The U.S. has emerged as a leading market for residential energy storage, supported by increasing solar adoption, declining battery costs, and growing demand for reliable backup power.
Market Overview
The U.S. Residential Lithium-ion Battery Energy Storage System Market has expanded rapidly as residential consumers increasingly seek energy reliability and greater use of renewable electricity. The residential segment has been growing faster than commercial and utility battery storage applications in the U.S.
Residential energy storage systems can store excess solar electricity and make it available when household demand increases. They can also provide backup power during grid outages. This combination of renewable energy generation, energy storage, and backup capability is creating new opportunities for battery manufacturers, solar companies, installers, and energy-storage providers.
The market nevertheless faces supply-chain challenges. Fortune Business Insights identifies increasing dependence on China for lithium-ion battery manufacturing as a factor that could affect market growth.

Market Trends
Growing Adoption of Renewable Backup Power
A major market trend is the shift toward renewable backup power. Residential lithium-ion battery systems can provide electricity during outages, while pairing batteries with solar panels allows homeowners to store excess renewable energy for later consumption.
Solar-plus-storage systems can support evening energy demand, provide backup power, and enable energy arbitrage. As battery manufacturing has expanded, the upfront cost of lithium-ion batteries has also declined, improving their accessibility for residential applications.
Increasing Solar-Plus-Storage Integration
The combination of rooftop solar and battery storage is becoming increasingly important in the U.S. Declining solar-system prices and government incentives are encouraging homeowners to install solar-powered energy storage systems.
The solar segment dominated the market in 2022 and is expected to continue its leading position during the forecast period, according to Fortune Business Insights.
Market Drivers
Favorable Government Policies and Incentives
Government policies and incentives represent an important growth factor for residential energy storage. The Self-Generation Incentive Program (SGIP) provides incentives for battery energy storage installations, while the Investment Tax Credit (ITC) has supported residential and commercial energy storage systems paired with solar.
According to Fortune Business Insights, the California Public Utility Commission had approved more than USD 1 billion in SGIP funding by 2024. The Energy Storage Tax Incentive and Deployment Act also proposed extending ITC eligibility to standalone energy storage systems without solar panels.
Declining Solar and Battery Costs
Declining solar-system prices and advancements in battery technology are encouraging residential consumers to adopt energy storage. Lithium-ion batteries offer high energy density, longer operating life, and lower self-discharge compared with lead-acid alternatives.
The combination of lower system costs and improved battery performance is helping make residential storage more practical for households seeking renewable energy and backup capabilities.
Market Segmentation
By Power Rating
Based on power rating, the market is divided into:
- 3 kW–6 kW
- 6 kW–15 kW
- 15 kW–30 kW
The 6 kW–15 kW segment dominates the market. Its leading position is attributed to increasing household energy demand and the growing installation of residential energy storage systems containing multiple batteries.
By Connectivity
The market is segmented into:
- On-grid
- Off-grid
The on-grid segment is expected to dominate because of the large number of U.S. households already connected to the electricity grid. On-grid systems can store electricity while remaining connected to the grid, whereas off-grid systems are generally designed for locations with unreliable or unavailable grid access.
By Operation
Based on operation, the market includes:
- Standalone
- Solar
The solar segment dominated the market in 2022 and is expected to maintain its position during the forecast period. Declining solar prices and government incentives are key factors supporting solar-paired residential battery storage.
Key Players
Major companies operating in the U.S. Residential Lithium-ion Battery Energy Storage System Market include Tesla, Generac, Panasonic, LG Chem, Enphase, Eguana, Sonnen, Fortress, and SimpliPhi.
Tesla's Powerwall product portfolio is identified by Fortune Business Insights as one of the widely used residential lithium-ion battery energy storage systems in the U.S. The company entered the residential energy storage market early and has invested in its energy storage products.
Regional Analysis
United States
The market is geographically analyzed across the U.S. and California. The U.S. represents the overall national market, with residential energy storage adoption supported by renewable energy expansion, declining technology costs, and policy incentives.
California
California is the largest consumer of residential lithium-ion battery energy storage systems in the U.S., accounting for more than 50% of the total U.S. market, according to Fortune Business Insights. The state's strong position is attributed to declining solar prices, increasing renewable-energy adoption, and supportive programs such as SGIP and ITC.
Competitive Landscape
The U.S. market features competition among battery manufacturers, energy-storage companies, solar technology providers, and power-system companies. Companies are using partnerships and acquisitions to expand their product portfolios and market presence.
In February 2023, Pramac GmbH, part of Generac Power Systems, announced the acquisition of REFU Storage Systems GmbH, a battery-storage hardware developer. In September 2022, LG Energy Solution announced plans to launch a home battery with capacities ranging from 10.6 kWh to 35.4 kWh, depending on the number of installed modules.
Other developments included Panasonic's EverVolt 2.0 Total Home Energy Solution, Enphase's expansion of its Encharge battery systems, and Briggs & Stratton's acquisition of SimpliPhi Power.
Future Outlook
The future of the U.S. Residential Lithium-ion Battery Energy Storage System Market is closely linked to residential solar adoption, battery-cost reductions, government incentives, and demand for backup electricity. As homeowners increasingly seek ways to store renewable energy and improve resilience during power outages, solar-plus-storage systems are expected to remain an important area of development.
However, supply-chain dependence remains a consideration. Fortune Business Insights notes that China accounted for more than 60% of global lithium-ion battery manufacturing, compared with around 10% for the U.S. The resulting dependence on imports, together with U.S.-China trade tensions, could create challenges for the domestic residential energy storage market.
