Protection of Load and Charge in Solar Power Management
solar power management is used for the protection of load and charges i.e. how the rechargeable battery is used to store energy with the help of solar energy. It includes protection methods for the battery to curb problems like overcharging, deep discharge, or under voltage which harm the life of a battery. The proposed system used a solar PV module as input and load (LED light) as an output. Further, the project can be enhanced by using a microcontroller and GSM modem to communicate the status o the system to control via SMS. This system can also be upgraded to normal UPS, when connected with the solar charger will convert to SOLAR INVERTERS/UPS with solar charge as a priority.
the protection of load and charge using solar power management. Solar energy is converted into electrical energy by photo-voltaic cells. This energy is stored in batteries during the daytime to be utilized during nighttime. The developed project has many advantages to existing devices. It deals with a controlled charging mechanism that avoids overcharge, deep discharge, and under/over voltage of the battery and load. Unless barriers like under/over charge are overcome, maintaining and increasing electricity supplies from solar energy will require the continuation of potentially costly policy support.
In this project, indications are provided by a LED for a fully charged battery and a LED indicates that the battery is charging. The charge controller uses a diode as a power semiconductor switch to ensure cut off the load in low battery or overloaconditionson when The battery gets fully charged, the LED stops glowing.
Diodes are used to regulate the amount of charge coming from the solar panel to protect the battery from getting overcharged. Adding to this, it can also be used to allow different loads and supply appropriate voltage. In this paper, the charge controller is used as a power semiconductor switch to ensure cut off the load in low battery or under/overload conditions. An experimental prototype was built and field results have proven the good performance of the developed project

this project is become very use full today's world. The demand for renewable energy (alternative energy sources) is increasing day by day as our non-renewable sources have started depleting. The other reason for increased demand is that it has a cleaner, easy setup and has a very low cost of maintenance during its operation. Due to this, solar-powered equipment and appliances are making their way into various sectors of our day-to-day life. This research paper deals with the scenario that storage or battery is needed to harness the solar energy when the sunlight is available and supply it in vice versa conditions. For this, a cost-effective system is built that charges a battery with the help of a solar panel, and protection is given to the battery in case of overcharge, deep discharge, and under voltage conditions. The block diagram, circuit diagram, and hardware design is discussed in this project.
