The global electricity demand is projected to grow at nearly 4% annually through 2027. Countries such as the United States, the European Union, and Japan are experiencing a significant surge in energy consumption.

According to the International Energy Agency (IEA), in 2024, solar PV became the leading source of electricity generation in the European Union, marking a major shift toward renewable energy. Similarly, China, the U.S., and India are expected to see solar PV contribute over 10% of their annual electricity generation between 2025 and 2027.

This increase in solar PV-based electricity generation is creating demand for solar equipment, such as solar inverters. Major players like Sungrow, TBEA, and FIMER have dominated the solar inverter shipments in 2024.

A solar inverter uses a clean, pollution-free, and renewable energy source to power household appliances, industrial equipment, utility grids, etc. The rise of the “clean energy economy” enables businesses and households to achieve energy self-sufficiency through various solar power inverters available in different configurations and sizes. Apart from standard inverters, solar photovoltaic inverter manufacturers are introducing technologically advanced inverter variants and related solar products to make greener and smarter energy available for many PV inverter applications.  In this blog, we have covered the list of major solar inverter manufacturers and the trends in the solar inverter industry in 2025. Keep reading to know more.

Top Solar Inverter Manufacturers in the World (2025) (listed in alphabetical order)

These companies are listed in alphabetical order.

What is a Solar PV Inverter?

A solar inverter (also known as a “solar PV (photovoltaic) inverter,” “solar panel inverter,” or a “solar module inverter”) converts direct current (DC) power output from solar panels into alternating current (AC).

Why is an inverter necessary in a solar panel system? Without an inverter, converting the electricity generated by a solar panel into usable electricity is not feasible.

A typical solar energy system consists of:

• Solar panels (absorb sunlight)

• A mounting structure (holds the panels in place)

• An inverter (converts DC into AC)

• Batteries (store extra power)

• A Balance-of-System (BOS) and

• A grid box

Among solar battery options, the lithium iron phosphate (LiFePO4) battery is suitable for solar power applications due to its good electrical performance, safety, stability, non-flammability, and easy maintenance.

The following types of solar PV inverters are commonly used for residential, commercial, and utility-scale installations:

Central Inverter

Central or large-scale grid inverters are utility-scale inverters ranging from hundreds of kWs to hundreds of MWs. Central inverters combine all the direct current received from solar panels and turn it into alternating current simultaneously.

Grid-tied Inverter/Grid Inverter

Grid-tied or grid inverters feed power into the electrical grid by corresponding phase and frequency. These inverters deliver power directly from the solar panels when solar energy is available and shut down automatically if there is a loss of supply from the utility.

Hybrid Solar Inverter

Hybrid inverters help store surplus solar energy in a battery system for self-use. A solar hybrid inverter can provide a small amount of backup power during a power outage and act as a standard solar PV inverter by exporting excess solar energy to the utility grid.

Micro-Inverter

A single micro-inverter works with each solar panel. A micro inverter transforms direct current into alternating current, and the aggregated output is routed to a grid or battery bank. Micro-inverters are small and portable, with all the features of central inverters. High in performance and compact size, micro inverters work well in various applications.

Off-grid Inverter/Regular Inverter

Regular or off-grid inverters are a great choice for boats, commercial buses, mountain cabins, RVs, vacation homes, and potential power outages. An off-grid solar inverter cannot synchronize with the electrical grid and draws power from a battery instead of working with the grid power.

String Inverter

A string inverter is connected to a string of solar panels, known as a “solar array.” Generally, a solar array consists of 15 solar panels.

String inverters combine the direct current received from solar arrays and turn it into alternating current. Such inverters are mostly used in commercial and residential solar system projects like carport, rooftop, ground mount, and tracker installations.
