With more than 300 million homes still living in the darkness, electricity in any form is a welcome step. Recently, the Indian Institute of Technology, Madras (IIT-M), in an association with the Telangana State Southern Power Distribution Company Ltd (TSSPDCL) and Rural Electrification Corporation (REC), has deployed an inverterless solar power system.
The system was installed in Ramunigundla Thanda, Kesya Thanda, Jogi Thanda and Mantriya Thanda in rural Telangana. With this, these hamlets, which were reeling under the darkness for many years, now have access to uninterrupted electricity.
How it works
The inverterless system constitutes a 125 kWh battery, a controller unit and DC loads, which operate on a 48V DC internal distribution line. Since it’s the DC distribution line, the system has the ability to run a DC fan, a tubelight, two DC bulbs, a DC mobile charger, a DC power socket and a remote controller to operate the fan and tubelight.
In addition, to remain updated about the functioning of the installed system, a remote monitoring system has been deployed to receive real-time data. The data is consolidated via mobile phones and synchronized to a central server.
