Solar energy is changed into a current by using PV (photovoltaic) cells. Throughout the daytime, the energy keep within the batteries is used to run the pump for agriculture. This project aims at developing a controlled charging mechanism providing protections for overcharge condition, deep discharge condition and below voltage state of the battery. This planned system is comprised of a solar water pump that reduces the utilization of inverters etc, so reducing the price of the project. Using the charge-controlled mechanism; the pump is operated at four totally different time slots. Difficulties like shifting the pump ON/OFF manually are overcome using this project.
There exists an intrinsic real clock (RTC) that keeps chasing the time and so switches ON/OFF the pump consequently. MOSFET’s are utilized by the charge controller as power semiconductor switches to confirm cutting off the load (DC Pump) in conditions like low battery or overload, while, the junction transistor is employed to bypass the solar power to a dummy load whereas the battery gets absolutely charged. So the battery is shielded from obtaining overcharged.
