Abstract
In this paper a method is proposed to develop and design an energy monitoring unit for prepaid charge controller. The energy recharge is achieved by master unit through dual tone multi frequency (DTMF) signal for prepaid charge controller. The energy recharge information is received by the prepaid charge controller and it monitors the energy consumption of the loads and disconnects the input power once the prepaid charge controller is out of balance. The amount of balance is stored on EEPROM of microcontroller. Based on energy consumption, it decrements the recharged energy units and displays the remaining energy units on the liquid crystal display (LCD). The energy monitoring section is tested and verified at 35W load. This is a more convenient way of purchasing energy credits and recharging the prepaid charge controllers in dc micro-grid system.
