From ABB to Zeversolar: The Top 19 Companies in the Solar PV Inverter Market

A PV inverter is a device that converts the DC current to AC current of the required frequency, which is then supplied to the electric grid. The device uses the maximum power point tracking (MPPT) technique to extract the max amount of power from an array of solar panels.

PV inverters are the most essential part of a solar power plant, and account for 10-15% of their overall cost.

Emerson Electric

Emerson Electric

Solar PV (photovoltaic) installations rely on arrays of solar cells to capture the sun’s rays during daylight hours. Emerson Industrial Automation designs and manufactures tracking systems (comprised of motors, gearboxes and intelligent software) that ensure solar arrays are positioned for maximum exposure to the sun.

Our high efficiency power conversion equipment transforms the captured solar energy into grid-ready AC power. Our innovative grid-tie inverters are designed as part of a modular architecture that is compact and scales easily. These inverters have built-in intelligence that maximizes energy yield by controlling the active and standby sequence for each module, and the modules are rotated so that duty is shared and inverter life is extended.

GE’s Power Conversion business provides a complete range of central inverters based on a modular and compact approach, and specifically designed for the solar industry. As part of GE’s ongoing development in power electronics technology, the solar inverters build on extensive experience with designing, manufacturing and installing more than 34 GW of converters for the renewable energy industry, and decades of experience in controls for a wide range of utility applications. The installed base covers the full range of utility scale requirements, including converters to meet stringent grid code requirements in extreme environmental conditions.


Mitsubishi Electric

Mitsubishi Electric is pursuing the development of products and technologies that contribute to increased efficiency in the use of PV systems, which continue to attract interest as a power generation method that does not emit CO2. The power generated through PV systems is a direct current that cannot be channeled to equipment and devices in its initial form. PV inverters convert this direct current into an alternating current form that can then be used to power equipment and devices. Increased conversion efficiency leads directly to the reduction of power generation waste.

The European organisation has its own development and manufacturing facilities, and provides local customer support in all European countries.



PROINSO is a company who focuses their activities in the field of Renewable Energies and more specifically in the area of Grid connected Photovoltaics.

When conducting a photovoltaic solar installation, the choice of materials to use or the company in which we place our trust throughout the course of our project is the most important decision. The cost is an important factor, but the system to be implemented must ensure full compliance with the requirements of the project and ensure its long-term duration.



The reduction of  environmental impact is a very important matter in terms of sustainability and quality of life. Energy resources extracted from oil are becoming scarce and the conversion to alternative sources of energy is both fundamental and necessary.

Based on this awareness, over the last few years, Riello has reconverted its products, enhancing the research to develop energy from renewable sources, focusing mainly on solar energy.
