This project aims to develop a solar powered UPS as an alternative energy source for rural areas in India. It consists of solar panels that convert solar energy to electrical energy, a charging circuit to charge a 12V DC battery, and an inverter circuit to convert the DC power from the battery to AC power. The system provides backup power during grid failures using energy stored in the battery. It has advantages like being renewable and reducing reliance on fossil fuels, while initial costs and dependence on sunlight are disadvantages. Potential applications include remote monitoring systems, communications, and transportation. The design is intended to produce the desired AC output from the solar-powered system.

3. ABSTRACT
▶
This Project provides the research and development of a solar powered UPS in India’s market as an
alternative source of energy.
We face unprecedented energy crisis in rural and suburban area. The problems become more severe during
summers. However, winter in no different as there was still an average power outage of 3-4 hours every
day.
Those without generators and UPS faced tremendous problems in these outages. The prices of both
continued to increase due to a sharp increase in their demand. We are not using solar UPS as there
replacement but it can be used as backup energy during grid failure.
This project consists of solar panel which consist solar cell which convert solar energy into electrical
energy. We also have charging circuit which will charge 12V DC (direct current) battery and inverter circuit
will convert itAC (alternative current).

4. INTRODUC
TION
▶ Solar power in India is a fast developing industry. As of December 2017 the country's solar power
had 17.05GW total capacity. India expanded its solar-generation capacity 8 times from 2,650 MW
on 26 May 2014 to over 20GW as on 31 January 2018.
▶ The improvements in solar thermal storage power technology in recent years has made this task
achievable as the cheaper solar power need not depend on costly and polluting coal/gas/nuclear
based power generation for ensuring stable grid operation.
▶ Most of the rural area still face the problem of electricity which force them to be reliable
on kerosene lamp. This major problem can be overcome by usage of solar energy. I have studied the
model through which this major problem can be eliminated

6. PROBLEM STATEMENT
The world demand for electric energy is constantly increasing, and conventional energy
resources are diminishing and are even threatened to be depleted. Moreover; their prices
are rising. For these reasons, the need for alternative energy sources has become
indispensable, and solar energy in particular has proved to be a very promising alternative
because of its availability and pollution-free nature.
Due to the increasing efficiencies and decreasing cost of photovoltaic cells and the
improvement of the switching technology used for power conversion, our goal is to
design an inverter powered by PV panels and that could supply stand-aloneAC loads.

11. SOLAR INVERTER ADVANTAGES:
▶ Solar energy is a renewable energy which helps in reducing global warming and greenhouse effect.
Solar energy helps in saving money as many people have started using solar based devices.
▶ Asolar inverter is really convenient for those people who use limited amount of energy.
▶ There is this synchronous solar inverter which helps both small homeowners and power companies
as they are large in size
▶ There is this multifunction solar inverter which is the best among all and works efficiently. It
converts the DCpower to AC very carefully which is perfect for commercial establishments This
inverter is effective in cost i.e. less expensive than generators
▶ Apart from solar inverters there are other devices too that make use of solar energy namely, solar
cooker, solar heater.Solar inverters are way better than normal electric ones.Also their maintenance
does not cost much money

12. SOLAR INVERTER DISADVANTAGES
▶ Initially you need good amount of money for buying a solar inverter.
▶ Its efficiency is totally dependent on amount of strong sunlight.
▶ The solar panels that are used to attract Sunlight requires lots of space as it depend on
amount of sunlight.
▶ Solar Inverters can work at no sun but it require fully charged battery.

13. APPLICATION
▶ Remote weather monitoring system.
▶ Remote communication system.
▶ Satellite communication.
▶ Solar power based transport system.

14. CONCLUSION
▶ Photovoltaic power production is gaining more significance as a renewable energy
source due to its many advantages.
▶ These advantages include everlasting pollution free energy production scheme, ease of
maintenance, and direct sunbeam to electricity conversion.
▶ However the high cost of PV installation still forms an obstacles for this technology.
Moreover the PV panel output power fluctuates as weather conditions, such as the isolation
level, and cell temperature.
▶ The describe design of the system will produce the desired output of the project. The inverter
supply anAC source from a DC source.
