Three Phase String Inverter Market Size

The global three phase string inverter market was valued at USD 16.7 billion in 2024 and is estimated to grow at a CAGR of 10.5% from 2025 to 2034. It is a type of solar inverter designed to convert the DC electricity generated by photovoltaic solar panels into AC electricity suitable for three phase power systems. These inverters are commonly used in commercial, industrial, and utility-scale solar installations due to their ability to handle higher power outputs and efficiently integrate with three phase grid systems.

Increasing demand for large scale solar installations will boost the product adoption on account of their ability to handle higher power outputs and deliver balanced electricity across multi phases. Rising demand for solutions offering seamless integration with the grid, especially in regions with robust three phase electricity distribution systems will improve the product demand. Additionally, their ability to manage voltage and frequency fluctuations contributes to grid stability, a crucial requirement for modern power networks, driving the business outlook.

Expanding need for cost-effective and scalable inverters with minimized cabling and installation complexities will foster the product adoption. Rising government support focused on encouraging renewable energy adoption and policies aimed at achieving net-zero carbon goals and transitioning to clean energy sources will spur the industry growth.
