Abstract :

This system is a system which is used to charge the battery with the maximum utilization of solar energy. This system consists of two relays. It is used for the switching modes of charging a battery. The voltage obtained from the solar panel is being sensed by the voltage sensor. Here the voltage should be within a certain limit. If the voltage is between (10-14V), then both the relays will be operating, besides the battery will charge through the solar energy. This mode is said to be solar mode. In other case, if the voltage from the solar panel is below 10V, the charge of the battery will be switched to EB mode. The voltage from the solar panel and different mode of the battery are displayed through the LCD display. When the EB mains are turned off, the voltage from the battery is discharged through this system. This project aims to make a simple solar charge controller which can be connected to the existing UPS and can act as a smart UPS. Solar panels will not supply the regulated voltage for charging the battery. Hence, an external charge controller is used to have the desired constant voltage. Development of this project as a product can eliminate the cost of the hybrid inverter.
