Development of portable case solar battery charger

This project aims to develop a Portable Case Solar Battery Charger that can be carried anywhere for the use of electronic and electrical devices. In the Portable Case Solar Battery Charger there are two main systems that play a major role which is battery charger circuit and battery voltage level indicator circuit. The function Battery charger circuit is to control the output voltage of the solar panel by using a variable resistor in the circuit. Meanwhile, the battery voltage level indicator circuit is used to monitor the voltage level of the battery by using the LED display. The output of this project is produced two types of output, which is direct current (DC) and alternating current (AC) by using converter circuit and the inverter device. Other than that, this project also involved with a design to ensure that the solar case is easy to be carry. Furthermore, the construction of the solar panel frame is also designed to facilitate solar panel to be placed in accordance with the position of the sun
