Valued at USD 14.37 billion in 2024, the solar inverters/PV inverters market is projected to reach USD 15.15 billion in 2025 and USD 24.63 billion by 2034, growing at a CAGR of 5.5% during the forecast period 2025–2034. Asia Pacific was the largest regional market in 2024. Key players include Huawei, Sungrow Power Supply, SMA Solar Technology AG, ABB Ltd., Sineng, TBEA, TMEIC, Schneider Electric, SolarEdge Technologies, Power Electronics, KACO New Energy Inc., Fronius, Wuxi Sineng, SunPower Corporation, Delta Electronics, Inc., Hitachi Hi-Rel Power Electronics Pvt. Ltd. and Siemens AG. This article reviews how string inverters, central inverters, microinverters, on-grid deployment and off-grid deployment shape product and purchasing decisions in the solar inverters/PV inverters market.

How Inverters Enable Solar Power

Solar inverters/PV inverters convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which can power appliances, feed the electrical grid or supply an off-grid AC network. Market growth is driven by environmental concerns and the need to reduce carbon emissions. According to the International Energy Agency, solar photovoltaic power generation increased by 270 terawatt-hours in 2022, accounting for 4.5% of total global electricity generation. Government incentives also matter: in September 2022, India's Ministry of New & Renewable Energy allocated USD 1.66 billion for high-efficiency solar PV modules under the Production Linked Incentive Scheme.

Product Share Led by String Designs

By type, the market comprises central inverters, string inverters and microinverters. String inverters accounted for the largest revenue share, at 49.10% in 2024. Connected to a string array, string inverters are known for efficiency and reliability, can handle high voltages and output, and perform reliably in extreme temperatures. Their comparatively fewer connections also make troubleshooting easier. In February 2024, Sungrow introduced its SG iNext series of string inverters, which the company says delivers significant efficiency improvements and enhanced grid support features, while Huawei focuses on innovating string inverters alongside energy storage and digital upgrades.

Utility-Scale and Residential Product Roles

In North America, recent trends include rising adoption of 1.5 MW central inverters and 60 kW string inverters. Although demand for string inverters has been robust, central inverters are anticipated to continue their dominance in the region because of scalability and efficiency in large-scale solar installations. Meanwhile, microinverters continue to see product activity. In May 2025, Enphase delivered 6.5 million US-produced IQ microinverters and 50 MWh of batteries from local factories, accounting for 80% of total shipments in 2025. In March 2025, Atmoce released MI series microinverters with an output range of 400 W to 500 W, supporting 700 W PV modules at a peak efficiency of 97.4%.

Grid-Tied and Standalone Deployment Models

The report segments deployment into on-grid and off-grid models. On-grid deployment feeds solar-generated AC electricity into the electrical grid, whereas off-grid deployment supplies an independent AC network. Improved efficacy, dependability and grid collaboration potential make the technology more attractive, and incentives aimed at bringing electricity to rural regions create opportunities for expansion. However, the absence of appropriate regulatory policies sizably impedes growth, and grid integration complexity is identified as a challenge. These factors define the commercial backdrop for both on-grid deployment and off-grid deployment.

Regional and End-User Landscape

Asia Pacific dominated the global market with a 46.10% revenue share in 2024, fueled by growing solar installations in Japan and China, while a positive outlook for product demand in India adds potential. North America accounted for a significant share, with the US a key contributor and a major market for various Solar Inverters/PV Inverters types. In Europe, Germany held the largest share and is expected to witness the fastest growth, supported by strong renewable energy policies, rising energy prices and expanding electric vehicle charging infrastructure. By end user, utilities held the largest share at 46.33% in 2024.

Manufacturing and Competitive Activity

Manufacturing locally to minimize operational costs is a key tactic among manufacturers. In June 2025, SolarEdge reached production of 250,000 inverters at its Austin facility, generating over 1,000 jobs and reinforcing supply resilience within the United States.
