This paper aims to build a microcontroller based SMPS full wave bridge power transfer system that will also incorporate some domestic alerting mechanisms, such as security-alert, mail notification, flooding, smoke detection etc. The solar energy is utilized to charge a battery, which in turn will power up the system to drive various modules. This helps the system to be a completely stand-alone device. Along with usage of renewable energy, the paper also aims at protecting the electrical devices in a domestic setting from power-fluctuations or a brown-out.
