U.S. Grid Forming Inverter Market to Grow at a CAGR of 22.70% Through 2035 as Asia Pacific Leads and Europe Emerges as the Fastest-Growing Region on Renewable Interconnection Mandates.

Austin, Sept. 08, 2026 (GLOBE NEWSWIRE) -- According to SNS Insider, the global Grid Forming Inverter Market was valued at USD 1,850.40 Million in 2025 and is projected to reach USD 15,320.60 Million by 2035, registering a CAGR of 23.6% from 2026 to 2035. The market is changing the dynamics of the way power systems stabilize as renewable energy penetration increases and as the role of conventional synchronous generation decreases, with utilities now demanding that their inverter-based resources provide synthetic inertia and black-start functionality. The size of the market was valued at about USD 2,287.50 Million in 2026E, which is early-stage acceleration as grid codes begin to establish the rules for interconnecting.

SMA Solar Technology introduced its Stability Enhanced DC Coupled Hybrid Solution with the introduction of the grid-forming Sunny Central Storage UP-S battery inverter solution at Intersolar Europe 2026.

Market Relevance

With the retirement of coal-fired and gas-fired plants, reducing grid inertia, the grid-forming inverter is transitioning from being an advanced technical specification to a mandatory requirement for connecting solar energy, wind energy, and battery energy systems to the grid. National standards update within countries like the United Kingdom, Australia, and the U.S. have made what was once an additional capability required for project approval.

Grid Forming Inverter Market Overview

Market scope includes string and central grid-forming inverters used in utility-scale renewable energy integration, microgrids, and distributed energy generation, catering to utilities and commercial & industrial applications. String Inverters dominate the type-based segmentation due to modularity and lower cost per unit, while Central Inverters represent the fastest-growing segment as utilities prefer centralized technology for gigawatts-scale battery installations and grid code testing.

Strategic Market Outlook

A number of growth opportunities are emerging in the field of offshore wind integration due to extensive subsea cabling and poor grid connectivity near the point of interconnection, making grid forming capabilities a necessity, as opposed to being an option. The emergence of revenue opportunities through the provision of grid services, in line with initiatives such as the Stability Pathfinder program in the UK, creates a business case for utilities and independent power producers to use grid forming equipment and manufacturers who scale their production and gain certification in advance to dominate the market before others catch up.

There is usually a 10%-25% premium price on grid forming inverters as compared to grid following inverters which may limit its usage in small scale projects and markets which haven't adopted the technology through mandatory interconnection rules, especially in the face of fragmented grid code standards in different regions.

Grid Forming Inverter Market Regional Analysis

Asia Pacific had the highest share in the Grid Forming Inverter Market in 2025, accounting for 57.60%, owing to large solar and wind capacities, renewable energy targets, and the presence of key players such as Sungrow, Huawei, and NingBo Deye Inverter Technology. China constituted about 41.30% of the revenue in the region, aided by the development of utility-scale renewables and storage, while India, Japan, and South Korea contributed additional demand through the development of solar parks and offshore wind, as well as interconnection frameworks.

North America had a notable share of the global market in 2025 due to growing renewable interconnections, battery storage, and growing importance of grid operators in managing the performance of inverter-based resources. The U.S. Grid Forming Inverter Market was valued at approximately USD 367.40 Million in 2025 and is projected to grow at a CAGR of approximately 22.70% through 2035, driven by rising renewable interconnection, declining system inertia from coal and gas plant closures, and the emergence of formal grid-forming interconnection frameworks.

Europe will be the fastest growing region with a compound annual growth rate (CAGR) of 26.80% between 2026 and 2035 due to the high level of renewable energy targets, fast decommissioning of synchronous coal and gas power plants, and mandatory requirement for grid-forming interconnections by transmission system operators.

Grid Forming Inverter Market Segment Analysis

By Type: String Inverters led the Grid Forming Inverter Market with the biggest market share, which was 46% in 2025, due to their modular structure, cheaper cost per unit, and success history in distributed solar PV and battery storage applications. Central Inverters are the most rapidly growing category, preferred by developers, such as GE Vernova, Siemens Energy, and Hitachi Energy for large-scale projects on gigawatts level, when centralized technology makes easier the testing of grid codes compliance.

By Power Rating: Above 100 kW category held the largest market share in terms of power ratings, at 52% in 2025, due to the high market penetration of utility-scale solar energy, wind, and battery storage systems, which need higher power ratings to provide substantial synthetic inertia and reactive power assistance. The Below 50 kW category is expanding at the fastest pace due to the increasing grid forming capabilities being installed in microgrid, commercial, and residential rooftop solar PV systems, with companies such as Enphase Energy and SolarEdge offering them.

By Application: Utility-Scale Renewable Integration was the largest segment in 2025 with 58% market share as the grid operators of Australia, UK, and some states of the U.S. began implementing their technical standards for synthetic inertia and voltage regulation in renewable energy interconnections. Microgrids & Distributed Energy Systems is the fastest growing application as increasing funding is being made towards resilience-based projects in communities and university or industrial campuses which use grid-forming inverters for maintaining frequency and voltage levels when not connected to the main power grid.

By End User: Utilities accounted for the biggest proportion among end users, constituting 61% of all end users in 2025, owing to the critical need for utilities to construct and maintain renewable and storage technology that would help stabilize the grid as traditional sources of power generation are phased out. The Commercial & Industrial sector is the most rapidly growing end user segment due to the installation of grid-forming inverters in data centers, manufacturing facilities, and campuses.
