The string inverter market is a vital segment of the solar photovoltaic (PV) industry. String inverters convert DC electricity generated by solar panels into usable AC power for residential, commercial, and small utility-scale installations. Compared to central inverters, string inverters offer better flexibility, easier maintenance, and scalability, making them ideal for small to mid-sized systems.
The global string inverter market was valued at USD 3.84 billion in 2023 and is anticipated to grow at a CAGR of 5.34% from 2024 to 2033.
