String Inverter Market Growth

Growing Demand for Single Phase and Three Phase String Inverters to Bolster the Growth Market

Based on phase, the single-phase string inverter accounts for a significant share in the market, and this trend is likely to be followed in the coming years as well. The reliability, efficiency and cost-effectiveness of the product can lead to increased demand of single-phase inverters in both residential and commercial sectors, hence propelling the growth of the string inverter market. Additionally, single-phase string inverters draw out the maximum amount of energy from the PV system and have a maximum input voltage of 600V.

Meanwhile, the three-phase string inverter type is anticipated to grow at a significant rate during the forecast period. This can be due to the ability of the product to manage voltage rise and reduce the change of appliance failures due to high voltages. The growing awareness about the grid stability provided by the three-phase string inverter is likely to aid the market growth in the forecast period.

Industry Outlook

As per the string inverter market dynamics and trends, India had around 61.97 gigawatts of installed solar capacity as of 2022. This makes India one of the top countries in the deployment of solar photovoltaic energy. The 2024-25 budget revealed that Indian government has allotted around Rs 10,000 crore for solar grid projects, due to the rising demand for energy from industrial sectors. Central string inverters are growing in demand due to their high usage in the utility scale PV projects in the country, owing to their cost-effectiveness and superior dynamic performance.

Researchers at Germany’s Fraunhofer Institution for Solar Energy Systems (ISE) announced the launch of medium-voltage string inverter for large-scale power plants. These inverters rely on silicon carbide semiconductors which can increase output voltage from 1,500V at 250kVA and usage of silicon instead of copper can save valuable copper resources. These inverters can boost the string inverter industry revenue.

Moreover, Sungrow, a solar PV inverter provider announced that it has established a strategic supply agreement with Gulf Energy Development in Thailand in March 2024. Under this agreement, the company is expected to provide solar inverter and liquid-cooled BESS equipment for 3.5GWp of Gulf Energy Development projects for the next 7 years. This equipment is expected to be deployed at ground-mount solar PV plant, solar-plus-storage hybrids and rooftop PV projects in the country, which can contribute to the growth of the string inverter industry.
