The Ministry of New and Renewable Energy (MNRE) has extended the Bureau of Indian Standards (BIS) certification compliance deadline for solar inverters above 200 kW capacity to June 30, 2026. Industry players importing or deploying large string and central inverters now have a brief but critical window to align with India's mandatory quality standards.
The India Angle
India's push to enforce BIS quality standards across its solar supply chain has been one of the most consequential policy developments for the inverter industry. Under the Solar Systems, Devices and Components Goods (Quality Control) Order, 2025, every solar inverter sold in India must carry BIS certification.
Key Highlights
- Applicable Category: Solar PV inverters with capacity above 200 kW
- New Compliance Deadline: June 30, 2026 (or until further MNRE orders)
- Governing Order: Solar Systems, Devices and Components Goods (Quality Control) Order, 2025
- Smaller Inverters (up to 200 kW): Already under mandatory BIS compliance from January 1, 2026
- Certifying Body: Bureau of Indian Standards (BIS) under IS/IEC standards
- Impact Sectors: Utility-scale solar, large C&I rooftop projects, KUSUM installations
Action Required
If you are an EPC company or solar developer deploying inverters above 200 kW, confirm BIS certification status with your supplier immediately. Do not commit to procurement timelines without a confirmed BIS certificate before the June 30 cutoff.
