The Ministry of New and Renewable Energy (MNRE) has extended the deadline for self-certification of high-capacity solar photovoltaic (SPV) inverters to support manufacturers facing delays due to limited testing infrastructure. The decision was announced through a notification published in the Gazette of India on July 8, 2026, under the authority of Joint Secretary Rajesh Kulhari.
According to the notification, the self-certification timeline for SPV inverters with a capacity above 200 kW, covered under items 4 and 5 of the relevant quality control framework, has been extended until December 31, 2026, or until further orders, whichever is earlier. The extension is intended to provide manufacturers with additional time to meet mandatory quality and safety requirements while ensuring that the transition to stricter compliance standards remains smooth.
The requirement for self-certification was introduced under the “Solar Systems, Devices and Components Goods Order, 2025,” which came into effect on January 27, 2025. This order replaced the earlier 2017 quality control framework and introduced updated standards for several solar products. Initially, manufacturers were given 180 days to comply with the new requirements for five specified product categories.
Recognizing the shortage of testing facilities and the practical challenges faced by manufacturers, the government later issued an amendment on August 5, 2025, extending the self-certification deadline for high-capacity SPV inverters until June 30, 2026. With testing capacity still limited, the ministry has now decided to provide another extension until the end of December 2026.
The latest notification also makes it clear that the extension is subject to strict compliance conditions. Manufacturers must hold valid IEC certificates corresponding to the prescribed Indian Standards for their products. For item 4, compliance is required with IS 16221 (Part 2): 2015 / IEC 62109-2: 2011 and IS/IEC 61683: 1999. For item 5, manufacturers must comply with IS 16221 (Part 2): 2015 / IEC 62109-2: 2011, IS 16169: 2019 / IEC 62116: 2014, and IS 17980: 2022 / IEC 62891: 2020.
In addition to these certifications, manufacturers must submit test reports issued by accredited laboratories to support their self-certification. Through this extension, the ministry aims to ease compliance challenges while maintaining high standards of quality, safety, and reliability for large-capacity solar inverters deployed across India’s rapidly expanding renewable energy sector.
