Abstract

This paper presents a low cost Solar Charge Controller (SCC) using Atmel Corporation ATmega8 microcontroller to control and coordinate the functions properly. Details of design for the construction of SCC using crystal oscillator, ceramic resistors, Light Emitting Diodes (LED) and MOSFET are presented. The source code for the ATmega8 microcontroller is written in Arduino IDE to obtain accurate and efficient automatic control action. Accordingly, battery can be disconnected from solar cell when overcharging and reconnected while discharging. The loads can be disconnected according to the over current and under flow current limit for both battery and PV. The proposed charge controller is equipped with LEDs to display the battery charging /discharging status, charge level and short circuit condition via microcontroller. The construction and operation of our proposed smart solar charge controller indicates that it is cost effective and functions properly.
