Indian Institute of Technology, Madras has won the IEEE Spectrum Technology in the Service of Society Award 2017 for its solar-direct current (DC) inverter system. The system uses the micro grid technology, and converts residential power from 230 Volt alternating current (AC) to 48 Volt direct current (DC) to power appliances and devices. The system is equipped to convert power generated through rooftop solar as well. Currently, the system has been deployed in 4,000 off-grid households in Jodhpur and Jaisalmer, Rajasthan, and is being deployed in around 7,200 households in Assam. The inverter system is also being installed in villages in Karnataka, Tamil Nadu, Odisha, Andhra Pradesh and Telangana.
