String inverters are the most common product technology worldwide, based mainly on their affordability, scalability, and well-established reliability for utility-scale and commercial solar projects. With less initial cost per watt than micro inverters and easier installation than central inverters, string inverters find a balance between efficiency and cost and are thus the go-to choice for large solar farms and commercial rooftops.
Their modular nature enables simpler maintenance and mitigation of partial shading by means of power optimizers, with newer models incorporating smart grid and battery-ready features.
Three-phase PV inverters are used most commonly all over the world, especially in commercial, industrial, and utility-type solar arrays, owing to their improved efficiency, equal power distribution, and suitability with grid infrastructure. The majority of electricity grids are based on three-phase power, and hence, three-phase inverters are necessary for larger systems (10kW and more) to maintain energy delivery stability and follow grid regulations.
They lead in industries with strong solar uptake, including Europe, China, and the Middle East, where utility-scale solar farms and commercial rooftops demand greater power output and grid synchronization.
Grid-connected (on-grid) PV inverters are used most extensively throughout the world with a share of more than 80%, thanks to their cost-effectiveness, easier design, and suitability with net metering regulations. The inverters supply electricity from the sun into the utility grid directly, making battery storage expensive and redundant and achieving a high return on investment through energy credits or feed-in tariffs.
They excel where the grid is solid and friendly toward renewable policies, including in Europe, North America, and China, where large-scale solar farms and roof installations thrive.
The most common PV inverters are in the range of 3 - 33 kW. This is due to their suitability for residential, commercial, and small-scale industrial solar installations that make up a majority of the solar energy industry. The inverters are a balance between cost, efficiency, and scalability and can, therefore, be used both for single-phase and three-phase applications.
Smaller inverters (≤ 0.5 kW and 0.5 - 3 kW) are generally employed for micro-generation and off-grid applications, whereas larger inverters (33 - 110 kW and > 110 kW) are mainly utilized for large solar farms and utility systems. Nevertheless, with the growing popularity of rooftop solar systems and medium-scale solar projects, the 3 - 33 kW category is still the most widely used.
The most commonly employed PV inverters are those in the range of 230 - 400 V. They are so, as they fit residential and business solar installations, which account for a large majority of the solar industry. A majority of residential and commercial units employ single-phase (230 V) or three-phase (400 V) electric systems, which means that the inverters of this range are the most convenient to connect to the grid.
Lower voltage inverters (≤ 230 V) are typically employed for small-scale or off-grid operations, whereas higher voltage inverters (400 - 600 V and > 600 V) are generally implemented in large-scale utility and industrial solar farms. The 230 - 400 V range offers an optimal balance of efficiency, safety, and compatibility with existing electrical infrastructure, rendering it the most widely utilized choice.
Residential PV inverters are most commonly utilized due to the widespread installation of rooftop solar globally. With increasing energy prices and government incentives for the use of solar, increasing numbers of homeowners are investing in solar energy to save on electricity bills and become energy-independent. Residential inverters, usually from 3 kW to 10 kW, are for single-phase or three-phase grid connection, thus perfect for household usage.
