Designing of hybrid automatic solar charging system with power controller for switching power utilization

Abstract

Production of conventional energy exhaust by every day, renewing to retrievable energy like wind energy, solar energy becomes necessity of the hours. The other reasons for the demand of solar energy are hazard free environment, Cary setup and low cost of maintenance during its operation and so on. A photovoltaic arrangement is used in solar energy system to convert heat and light energies to AC power with the help of inverter. In photovoltaic arrangement there are photovoltaic module, rechargeable battery, charge controller and inverter. Charge controller unit plays a significant role in this system to withstand battery charges for many hours and battery lifetime. This research provides the design of a solar energy controller for the battery charging unit with the function to connect and reconnect battery from the load during overcharging & discharging by using switches. A value added unit is available for power controlling, cutoff the power usage by the load and bypasses the solar energy to load with the help of electromagnetic-relays. Here the prototype system has been simulated for the 5 Volts battery and the same module has been implemented for 12 Volts battery.
