According to the report, the string inverter market is anticipated to grow from USD 6.1 Billion in 2025 to USD 10.5 Billion in 2035 at a CAGR of 5.6% during the forecast. The growth is being driven by growing utility-scale solar PV installations, leading to decentralized energy demand, and a need for smart, efficient and digitally connected grid solutions.
The growth in solar PV installations and increased investments in grid digitalization is promoting argumentation in the string inverter industry. Huawei invested in its FusionSolar to include AI-based monitoring capabilities, SMA Solar developed and added residential products with IoT connectivity capabilities, and Sungrow announced a higher rated capacity hybrid inverter to be utilized in utility projects. Additionally, ABB, FIMER, and Growatt are growing and developing product portfolios to meet the demand for decentralized energy. The significant backing of policy makers focused on renewable energy, falling costs of solar PV, and the added interest of "smart" grid capabilities will support robust growth in the String Inverter market until 2035.
The global string inverter market is rapidly advancing, driven by the overall uptake of solar PV, all the rooftop installations, and the integration of renewable utility-scale power. The newest offerings in string inverters are now including AI-based diagnostics, IoT-based grid connectivity and a higher DC/AC ratio that improves efficiency, flexibility and performance in market segments of residential and utility. For example, in 2025 Huawei and Sungrow expanded their high-capacity smart inverter product line for large solar farms, and SMA Solar and Growatt improved their residential offerings, indicating that digitalization and flexibility are becoming fundamental differentiators in the market.
One of the main limitations includes vulnerability to price pressures, supply chain uncertainty, semiconductor shortages and competition which makes it difficult for small industries to be profitable. Furthermore, adherence to grid codes and compliance relating to integration complexities are barriers to widespread utility-scale deployment.
However, there is considerable upside potential from government-backed incentives for solar, decentralized energy systems and national energy targets for new clean energy requirement generation. Owing to growing public sector strategic investment in the APAC, Europe and USA markets, we are likely to see acceleration in uptake, expansion in manufacturing capabilities, and greater adoption of string inverters as facilitators of a decentralized, smart grid future.
String inverter prices and access to the market continue to be significantly impacted by tariff policies due to the deep reliance on cross-border supply chains to obtain solar equipment. The elevated tariffs on Chinese product exports in PV and inverters are already requiring manufacturers to consider production location changes as well as to localize assembly and/or business models in order to remain relevant and competitive.
In general, the increase in tariffs expedites geography/ramp-up of regionalized production, increases uncertainty or exposure to price variation, creates go-to-market strategies focused on localization and joint venture relationships, boosts capacity for innovation in low-cost inverters to counteract higher import prices, facilitates the acceleration of government-supported regional incentive for manufacturers, and allows for long-term supplier contracts to reduce supply chain reliance and ensure stability with any policy change.
