PV Inverter Market Forecast 2035 | String Inverters, Central Inverters, Hybrid Solar-Storage Inverters, Microinverters, Three-Phase and Single-Phase Grid-Tied Inverters for Utility-Scale, Commercial, Industrial & Residential Solar PV Applications

The PV inverter market encompasses string inverters, central inverters, hybrid solar-plus-storage inverters, microinverters, power optimisers, and multilevel grid-tied inverters for utility-scale, commercial and industrial (C&I), and residential solar PV applications. The global PV inverter market is projected to reach USD 18.6 billion by 2035 at a 8.4% CAGR, driven by solar PV capacity additions growing at 350-500 GW annually requiring new inverter supply, hybrid inverter replacing string inverter for solar-plus-storage integration, utility-scale central inverter demand growing with multi-GW project scale, and SiC (silicon carbide) semiconductor technology enabling higher efficiency and smaller inverter form factors.

PV inverters are the power electronics brain of a solar installation: they convert the DC electricity generated by solar modules into grid-compatible AC electricity, implement maximum power point tracking (MPPT) algorithms to extract maximum energy from the module regardless of partial shading or temperature, and increasingly serve as the grid interface for reactive power, frequency response, and grid support functions. Sungrow has overtaken Huawei to become the world’s largest solar inverter manufacturer by annual shipments, driven by aggressive pricing, the broadest utility-scale central inverter portfolio, and a strategic push into energy storage that enables system-level integration of PV inverter and BESS in a single co-located project.

Executive Snapshot

What is the PV inverter market?
The PV inverter market encompasses string inverters, central inverters, hybrid solar-storage inverters, and microinverters for utility-scale, C&I, and residential solar PV power conversion from DC solar generation to AC grid output.

What is driving PV inverter market growth?
Solar PV capacity additions at 350-500 GW annually requiring new inverter; hybrid inverter replacing string inverter for solar-plus-storage integration; utility central inverter demand with multi-GW project scale; and SiC semiconductor enabling higher efficiency inverters.

What are the main PV inverter types and when is each used?
String inverters connect multiple modules in series strings and are the dominant residential and C&I technology; central inverters handle 1-5 MW DC input from multiple string combiner boxes for utility scale; hybrid inverters include an integrated battery charge controller for solar-plus-storage; and microinverters convert each module independently providing module-level MPPT and monitoring, optimal for partially shaded rooftop systems.

What is the impact of SiC semiconductor technology on inverter performance?
Silicon carbide (SiC) MOSFETs operate at higher switching frequencies than silicon IGBTs, enabling smaller magnetics and capacitors, higher conversion efficiency (up to 99%+ peak), and higher operating temperatures without derating. SiC inverters reduce balance-of-system costs by enabling smaller, lighter inverter form factors and are becoming the standard in premium string and utility central inverters above 50 kW rating.

Which regions lead the PV inverter market?
Asia-Pacific leads at 52% driven by China domestic solar installation volume and Chinese inverter manufacturers’ global market share; Europe is the second-largest market driven by SMA, Fronius, and European inverter specification for quality and grid code compliance; North America follows driven by IRA-driven solar deployment.

What does the PV inverter market look like in 2035?
Hybrid solar-storage inverter becomes the standard product replacing standalone string inverter in residential and C&I; grid-forming inverter capability becomes mandatory grid code requirement; and AI-powered inverter MPPT and grid support optimisation becomes standard in utility central inverters.

Consultant POV

“The PV inverter market is technology-driven and fiercely competitive, with Chinese manufacturers Sungrow and Huawei controlling over 40% of global volume through aggressive pricing and broad product portfolios. SMA Solar Technology and Fronius are the European quality leaders with the strongest installed base for replacement market. SolarEdge and Enphase have built the leading positions in North American residential inverter through differentiated MLPE and software ecosystems that command significant premium over commodity alternatives. The most significant technology transition is to hybrid solar-storage inverters: as battery storage becomes standard in new installations, the inverter specification process shifts from pure power conversion efficiency to system-level integration capability, software sophistication, and storage chemistry compatibility.”
