Localization is no longer a preference. It is law, economics and national mission, all arriving together. Brands caught between these clocks have three options: build a design team over 18–24 months, keep importing into a regulatory dead end, or partner with a specialist design house.
Under IS 17017 and the omnibus technical regulation, EV supply equipment sold in India requires BIS conformity. AC chargers, DC fast chargers and light-EV charging alike. Rebadged imports without compliant design files face an existential problem.
Grid-connected solar inverters need BIS IS 16221 certification and ALMM listing for government-linked demand pools like PM Surya Ghar, and DISCOMs are now extending that requirement to net-metering approvals. Imported-inverter brands are being pushed out of the largest demand pools.
India's household and commercial backup market is migrating from lead-acid-era designs to lithium systems. Every incumbent inverter and UPS brand needs redesigned power stages, battery-management integration and new firmware. That is a full product generation, not a refresh.
Thirteen projects approved (~₹1.64 lakh crore committed), first fab silicon targeted late 2026, operational OSAT capacity, and ISM 2.0 aimed squarely at Indian design capability and indigenous IP. The national direction is unambiguous: design in India, make in India.
India runs on imported power electronics, up to 65–75% of bill-of-materials value in categories like EV charging. That pattern is now breaking, by law. BAE exists to receive the engineering spend coming home.
