We live in a wired world, where nearly everything in our lives requires a steady supply of electricity to remain in operation. Sometimes extreme weather conditions, car accidents, falling trees, unusually high power demands, or even damage caused by animals can cause severe disruptions in a local or regional electrical grid, leaving our home without electricity for hours or more at a time. So, we use inverter in our houses. Inverters are widely used in the domestic as well as industrial environments to serve as a second line of source. A solar inverter’s main job is to convert DC power generated from the photovoltaic cell into AC power.

Hybrid inverters go a step further and work with batteries to store excess power as well. But this solar inverter system is inefficient in charging the battery during cloudy weather condition. The battery requires more than 1 Ampere current for proper charging and due to low capacity of the battery, when solar power is not available. the battery dies out with the use of heavy load appliances. To solve this problem, we made a “Hybrid Inverter with Solar Battery Charging”. This project is designed in such a way that it overcomes the limitation by the use of only solar energy. Electricity from the solar panel is generated only during the day, with peak generation around midday.

This generation fluctuates with various weather conditions and as there is no generation in the night, it is not possible to constantly supply the demands from the load end. When solar power is not available or insufficient to supply the load demands and if the mains power supply is available, then this “Hybrid Solar Inverter” switches to AC mains power supply for supplying the load. This power supply then charges the battery for using it as back up for the next time when there is a power outage in the mains. The use of solar panel to charge the battery gives an additional advantage of surplus power in case the power outage of mains is prolonging. Thus this inverter can last for longer duration’s and provides uninterrupted power supply to the user.

An intelligent hybrid inverter or smart grid inverter is a new generation of dedicated U.P.S. (Uninterruptible Power Supply) system which can use both electrical as well as solar energy to charge the system storage battery which can be used to generate electricity in the absence of either or both of energy sources. Usually electricity from solar panels is generated only during the day, with peak production around midday. This electricity is fluctuating and not synchronized with the electric consumption of the household. To overcome this gap between what is produced and what is required during the evening when there is no solar electricity production, it is necessary to store energy for later use and manage energy storage and consumption in an intelligent way.

 

Special Features:

Automatically battery charging by two ways (Solar Power Supply/Main Power Supply). When solar power supply is not available then battery charging is done by main power supply (AC mains). Otherwise, battery charging occurs through solar power supply.

Optimal utilisation of solar energy.

Uninterrupted power supply. In case of power outage from either or both the power sources (Solar power and AC mains) the battery provides backup and continues to supply the load.

Low maintenance cost. This inverter does not require frequent servicing 

Apparently we don’t have so much of sources for production of “Clean Energy” and on the other hand, we do actually have that much more sources and power plants to produce conventional energy such as thermal power plants, diesel power plant as well as nuclear power plants, the raw ingredients of which are bound to come to an end.

As clean energy can be derived from force of water or wind as well as from the energy we get from the sunlight which we don’t have any limitations too, it would be wise for us to be innovative and as we are advanced enough, to use those sources rather than to replenish the conventional ones. So, with that very idea in mind, we chose to exhibit our project of a “Hybrid Inverter with Solar Battery Charger” to kinder the minds of the youth as well as the elderly today to indulge more towards clean energy that’ll be beneficiary to everyone living and to live on our dear planet.

Conclusion:

Sun, being source of clean, pollution-free energy and Photovoltaic power production is gaining more significance as a renewable energy source due to its various advantages. The advantages include everlasting production scheme, ease of maintenance, and direct sunbeam to electricity conversion. However the high cost of installations still forms an obstacle for this technology. Moreover the PV panel output power fluctuates as the weather conditions, such as the luminosity of the solar beam, cell temperature etc.

The desired design of the system will produce the desired output of the project. The inverter will supply an AC source from a DC source. 

The project described is valuable for the promising potentials it holds within. Ranging from the long run economic benefits to the important environmental advantages. This work will mark an attempt and contribution in the field of renewable energy and can be implemented extensively.
