Photovoltaic Inverter

　　A photovoltaic (PV) inverter is a power electronics device used in the solar power generation sector to convert the direct current (DC) generated by PV modules into alternating current (AC) for delivery to local loads or the utility grid, and it is equipped with relevant protective functions. Depending on the application, PV inverters can be classified into grid-tied inverters and off-grid inverters. The power ratings of PV inverters span a wide range, from micro-inverters used in distributed grid-connected systems—as small as just over 100 watts—to large inverters used in centralized grid-connected systems—as large as several hundred kilowatts.

　　Due to differences in grid standards and grid-connection policies across countries, the testing and certification of grid-tied PV inverters involves numerous standards, complex requirements, and lengthy processes.

With the growing popularity of green energy conservation and environmental protection, PV products have garnered significant attention, and both their international and domestic markets are experiencing rapid growth. Governments around the world are also stepping up policy support for domestic grid-connected PV power generation projects. As a core component of PV power generation applications—and one closely tied to power generation efficiency—grid-connected inverters hold immense market potential. Faced with such business opportunities, how to obtain certifications from various countries in a short period of time and quickly capitalize on these opportunities has become an urgent issue for Chinese manufacturers to resolve.

Certifications required in major markets for solar PV grid-connected inverters include:

European TUV/CE certification; U.S. ETLus certification

Canada cETL certification; China’s Golden Sun certification

Australia SAA certification; testing and certification according to standards in other countries and regions
