As the world is nearing to a technological singularity our energy needs are increasing day by day. Not only we need to reduce the energy consumption from non renewable sources for the betterment of mother earth but also need to reduce cost. We would need a system which intelligently switches between these energy sources according to the load demand.This system will try to maximize the power from renewable sources like solar energy and use it whenever possible. Our system is specifically is designed to be used with solar PV-systems. This system is designed to be used specifically with on grid type solar inverters. These type of inverters do not have storage capability, instead they take power from other energy sources to synchronize with phase and frequency. This accounts to approximate 30 % of power supplied by inverter, rest will be supplied the solar cells. This system monitors load power requirement with the help of a energy meter. It will also have a smart switch connected to it for switching between other loads when the PV-system is unavailable. To the switch energy sources like DG generator and Grid power can be connected. It will also have a SD card and flash/EEPROM memory interfaced for storage of past data collected. System will also be interfaced with RTC for real time data collection and monitoring.
