MNRE Extends BIS Certification Deadline for Above 200 kW Solar Inverters till December 31
The Ministry of New and Renewable Energy (MNRE) has extended the self-certification deadline for BIS compliance of solar PV (SPV) inverters above 200 kW till December 31, 2026, citing limited testing infrastructure.

The decision follows the government's assessment of the limited availability of accredited testing facilities and the need to provide additional time for industry compliance, MNRE stated in a notification.
The notification pertains to Items 4 and 5 under the Solar Systems, Devices and Components Goods Order, 2025, which was issued on January 27, 2025, replacing the earlier Solar Photovoltaics, Systems, Devices and Components Goods (Requirements for Compulsory Registration) Order, 2017. The 2025 order introduced mandatory BIS registration requirements for five categories of solar products after a 180-day transition period.
This latest notification supersedes the earlier extension granted on August 5, 2025, under which self-certification for SPV inverters exceeding 200 kW had been permitted until June 30, 2026.
Under the revised timeline, manufacturers of SPV inverters above 200 kW can continue to avail self-certification, provided they possess valid IEC certificates corresponding to the prescribed Indian Standards and test reports from accredited laboratories.
