The Power Conversion System Market is expanding rapidly as utilities, developers, and industrial users install batteries at a record pace, and every project needs bidirectional converters to move power between storage and the grid. BloombergNEF reported that 112 GW and 307 GWh of storage were added worldwide in 2025, 48 percent more than in 2024, and expects about 158 GW in 2026. Revenue in this report covers the converter value of bidirectional power conversion systems and hybrid storage inverters for stationary battery systems, including units sold inside integrated blocks, and excludes photovoltaic-only inverters, uninterruptible power supplies, vehicle chargers, and motor drives. Chinese suppliers lead shipments, while European, Japanese, and American firms compete on grid-forming control, medium-voltage skids, and local manufacturing.

⮞In June 2026, LUTERRA, a grid-forming Smart String energy storage system was unveiled by Huawei Digital Power at Intersolar Europe in Munich. This system increases AC voltage to 1,000V through silicon carbide and provides six grid-forming capabilities such as inertia, short circuit, and black start among others with an example of Huawei citing a 400MW solar and 1.3GWh storage capacity at Red Sea resort microgrid.

U.S. Power Conversion System Market Outlook

The U.S. Power Conversion System Market was valued at USD 1.45 Billion in 2025 and is expected to reach USD 4.63 Billion by 2035, growing at a CAGR of 12.31% from 2026-2035.

The U.S. Power Conversion System Market is expanding quickly as utilities, solar developers, and data center operators add batteries at a record pace, and every system needs bidirectional converters. Wood Mackenzie recorded 18.9 GW and 51 GWh of installations in 2025, up 52 percent in gigawatts from 2024, with utility-scale projects supplying 16 GW and residential systems 2.7 GW. SEIA and Benchmark expect about 71 GWh in 2026, after a record 20.2 GWh in the second quarter. Suppliers are localizing production to answer trade measures and content rules, and storage converters are now built or planned in Texas and Pennsylvania. Residential demand is expected to soften in 2026 after the expiry of a federal tax credit.

⮞In September 2026, Flex agreed to acquire EPC Power, a Poway, California, maker of power conversion systems, for USD 4.40 billion, with closing expected in the fourth quarter of 2026. The deal brings EPC Power's Agile Grid Forming technology and its expanded U.S. manufacturing footprint into Flex's Cloud and Power Infrastructure segment.

By Type, Standalone Dominates the Power Conversion System Market and Integrated Grows Fastest

Standalone units hold the largest revenue pool because most utility-scale developers still buy converters separately from batteries, which lets them compare suppliers on efficiency, grid-code compliance, and service terms. Central and string designs from Sineng, Kehua, Sinexcel, SMA, and Power Electronics are supplied to system integrators in blocks of one to several megawatts, and buyers often reuse the same converter platform across different battery chemistries. Independent power producers in China, India, Chile, and Australia favor this route because it protects them from single-vendor dependence on cells. Replacement demand also adds volume as early projects reach the end of their first warranty periods.

Integrated systems are growing fastest because buyers prefer one supplier accountable for cells, converters, thermal management, and controls, which shortens commissioning and simplifies warranties. Tesla's Megapack 3 ships with an integrated inverter, Sungrow's PowerTitan 3.0 places a 1.78 MW converter in the same 20-foot container as 7.14 MWh of batteries, and Huawei's Smart String platform distributes converter modules across the rack. Factory pre-assembly cuts site labor and lets suppliers promise delivery times measured in days. Revenue attributed to the converter is smaller in each such system, yet rising shipments of complete blocks move a larger share of converters through this channel each year.

⮞In September 2026, Tesla began producing the Megapack 3 at its Brookshire facility outside Houston, Texas, a site planned to reach 50 GWh of annual capacity. The 5 MWh, 2.5 MW unit includes an integrated inverter, and up to four units combine into a 20 MWh Megablock, with deliveries expected toward the end of 2026.

By Power Rating, 500 kW to 2 MW Dominates the Power Conversion System Market and Above 2 MW Grows Fastest

Converters between 500 kW and 2 MW lead because they match the building blocks of most commercial, industrial, and utility projects and fit standard containers and skids. Typical products include Kehua's 1.25 MW and Sinexcel's 1.725 MW central units and Delta's 1.1 MW bidirectional model, and they are paralleled to form plants of hundreds of megawatts. Chinese and Indian procurement practices favor units in this range, and cost per kilowatt has fallen as volumes rose. The class also suits retrofits at existing substations, where transport limits, familiar maintenance practices, and a deep supplier base reduce risk for owners and lenders.

Units above 2 MW are advancing fastest as developers chase lower balance-of-plant cost per megawatt and fewer connection points. Inovance showed a 2.5 MW centralized converter with grid-forming control and turnkey stations from 3.45 MW to 12.5 MW at Intersolar Europe 2026, SMA offers the Sunny Central Storage UP-S 4600, and Heron Power plans a 5 MW medium-voltage unit that pairs inverters with solid-state transformers. Trade coverage of SNEC 2026 described larger power ratings as a defining trend. Higher ratings need silicon carbide devices, better cooling, and stronger grid-code validation, so suppliers with certification records gain an edge in tenders.

⮞In June 2026, Inovance Technology showed its next-generation storage lineup at Intersolar Europe in Munich, including a 2.5 MW centralized converter with grid-forming control and turnkey stations rated 3.45 MW to 12.5 MW. The company also showed a 432 kW liquid-cooled string converter and cited 50 GW of annual converter design capacity at its Xi'an base.

By Application, Grid Services Dominates the Power Conversion System Market and Backup & Microgrids Grows Fastest

Grid services lead because standalone batteries earn revenue from frequency regulation, capacity payments, reserve products, and arbitrage, and each of those functions depends on fast, accurate converter response. In China, standalone projects made up 58 percent of new-type storage additions in 2025 according to CNESA, and Kehua's 180 MW/360 MWh Indian plant and Sineng's 300 MW/1,200 MWh Zhangye plant are typical examples. Transmission operators in Europe are adding grid-forming expectations, which raises the specification and price of converters. Contracted availability payments make cash flows predictable, which helps developers finance large fleets.

Backup power and microgrids are growing fastest as data centers, industrial campuses, islands, and remote communities seek firm supply from batteries paired with solar or generators. AI computing loads create sharp power swings and long interconnection waits, and converter suppliers are responding with medium-voltage skids and solid-state designs. Dynapower markets its MV Integrated PowerSkid for data centers, hydrogen, and storage, Ingeteam is working with Mitsubishi Heavy Industries on U.S. data center power, and Huawei cites a Red Sea resort microgrid backed by 1.3 GWh of storage. Islanding, black-start, and seamless transfer functions command premium pricing, which lifts revenue per megawatt.

⮞In October 2026, SMA announced that the grid-forming capability of its Sunny Central Storage UP-S 4600 battery inverter received prototype confirmation from the certification body of M.O.E. under VDE FNN Guideline 2.1. The process combined testing, simulation, and model validation, and SMA cited its Blackhillock and Föhren storage systems as grid-forming deployments.

By End-User, Utilities & IPPs Dominates the Power Conversion System Market and Commercial & Industrial Grows Fastest

Utilities and independent power producers account for the bulk of purchases because grid-scale batteries make up the large majority of additions, with BloombergNEF putting utility-scale projects at 85 percent of the 2025 total. These buyers run competitive tenders, demand extensive grid-code certification, and sign multi-year framework agreements with converter suppliers such as Sungrow, Huawei, SMA, and Power Electronics. In Saudi Arabia, Chile, India, and the United States, utilities and developers procure blocks of several hundred megawatts at once, rewarding vendors that offer local service teams and spare-parts depots. Revenue certainty from capacity contracts keeps this group at the center of demand.

Commercial and industrial buyers are the fastest growing group as rising tariffs, demand charges, and supply-security concerns make behind-the-meter batteries attractive for factories, data halls, and logistics sites. Sinexcel’s 1,725 kW converters at an aluminum producer in Sichuan show how heavy industry uses storage to shift load away from peak tariffs, while Eaton’s xStorage and Schneider Electric’s skid-based offerings are targeted at campuses in North America and India. These purchases are characterized by small ratings, modular cabinets, and software for tariff optimization. Hybrid designs that connect solar, batteries, and generators through one converter widen the addressable base beyond utilities.

⮞In April 2026, Sinexcel announced grid connection of a 107.12 MW/428.48 MWh storage system at Zhongfu Industrial's aluminium plant in Guangyuan, Sichuan, using 104 of its 1,725 kW converters. The company estimates savings above CNY 60 million a year through peak shaving and describes the system as an iconic commercial and industrial project in China.

Market Dynamics

Growth Drivers: Record Storage Deployment and Falling System Costs and Grid-Forming and Data Center Requirements

Record storage deployment combined with falling system costs underpins demand, because every battery project needs a converter sized to its power rating. BloombergNEF reported 112 GW and 307 GWh of additions in 2025 and expects about 158 GW and 459 GWh in 2026, while CNESA recorded Chinese winning system bids from as low as CNY 391.14 per kWh. Lower battery prices improve project returns, which pushes developers to commit larger fleets and sign multi-year converter framework agreements. Utility-scale projects supplied 85 percent of 2025 additions, concentrating demand in high-power converters and medium-voltage skids from suppliers able to ship in volume.

Grid-forming requirements and data center load form the second driver. Trade coverage of SNEC 2026 described grid-forming capability as rapidly becoming a standard requirement rather than a premium feature, and the converter is the device that provides inertia, voltage support, and black-start functions. SMA links its grid-forming battery inverter to the German inertia market, and Kehua cites grid-forming credentials in India. AI data centers add sharp load swings and long interconnection waits, prompting Ingeteam, Dynapower, and EPC Power to develop converters for that market, which broadens the customer base beyond utilities.

⮞In June 2026, Power Electronics announced that its installed AC power had reached 170 GW, up from 150 GW at the end of 2025, with a target of 190 GW by the end of 2026. The company said storage growth is strongest in the United States, Australia, and the United Kingdom, and its PCSM and Multi PCSM inverters connect directly to medium-voltage networks.

Restraints: Price Competition and Margin Pressure and Trade, Interconnection, and Policy Uncertainty

Price competition compresses margins as dozens of suppliers chase the same tenders. CNESA reported 690 system tenders in China in 2025, with winning system bids ranging from CNY 391.14 to CNY 913.00 per kWh, and the spread shows how aggressively bidders discount to win volume. Converter content is a shrinking share of each system as batteries, integration, and construction are bundled, so suppliers must raise efficiency and power density just to hold revenue per megawatt. Consolidation is under way, with Flex agreeing to buy EPC Power for USD 4.40 billion and ABB acquiring Gamesa Electric, and smaller vendors without scale face the most pressure.

Trade measures, grid-connection queues, and policy uncertainty slow orders outside China. Wood Mackenzie counted 530 GW of projects in U.S. interconnection queues at the end of 2025 and noted that installations through 2031 depend on load growth, trade policy, and foreign-entity guidance, with scenarios spanning 52 GW. The India Energy Storage Alliance flagged China's battery material export restrictions and the financing of low-tariff projects as risks. Residential demand can swing quickly, with Wood Mackenzie expecting U.S. residential storage to contract by 2 percent in 2026 after a tax credit expired, and such swings complicate factory investment decisions for converter makers.

Opportunities: Data Center and Medium-Voltage Architectures and Emerging Markets and Fleet Upgrades

Data centers and medium-voltage, solid-state converter architectures open a new addressable market. Flex framed its purchase of EPC Power around 800-volt data center power architectures, Ingeteam and Mitsubishi Heavy Industries agreed in October 2026 to offer power conversion solutions to U.S. data centers, and Heron Power is developing a 5 MW medium-voltage converter that combines bidirectional inverters with solid-state transformers, with RWE Americas testing it at a Texas wind site. Converters that also handle power quality, ride-through, and grid support let batteries serve AI loads and the grid at once, raising content per project well above that of a conventional storage converter.

Emerging storage markets and fleet upgrades provide a second path. India tendered 102 GWh in 2025 according to the India Energy Storage Alliance and approved a second viability gap funding tranche for 30 GWh of standalone storage, Brazil is preparing its first battery capacity reserve auction, Saudi Arabia is building multi-gigawatt-hour systems, and SolarPower Europe projects 99 to 179 GWh of new European additions by 2030. Local value-addition requirements in India favor suppliers such as Delta, which builds converters in Tamil Nadu. Early-generation fleets in China, the United States, and Europe will also need converter replacement and software upgrades, creating service revenue.

⮞In October 2026, An agreement between Ingeteam and Mitsubishi Heavy Industries was made with the purpose of marketing, integrating, and developing energy solutions for American data centers using Ingeteam's power conversion equipment and software in conjunction with the services of the MHI group. The partnership may also explore the possibility of collaborating on medium voltage distribution and energy management solutions.
