, Description:BACKGROUND
Field of the invention
[001] Embodiments of the present invention generally relate to a power supply system and particularly to an uninterruptible power supply system.
Description of Related Art
[002] Human activity is overloading an atmosphere with carbon dioxide and other global warming emissions. These gases act like a blanket, trapping heat. The result is a web of significant and harmful impacts, from stronger, more frequent storms, to drought, sea-level rise, and extinction. Most of the contribution has resulted from energy generation. With every growing day, a need for energy is increasing to satisfy growing demands of energy production. This is further resulting in more global warming. This entire loop was inevitable until renewable sources were bought in a mainstream.
[003] Traditionally, the energy generation was mainly done using non-renewable resources such as nuclear power sources, thermal power sources, and so forth. Resources such as crude oil and coal were extracted and harvested at a rapid rate. However, to reduce a rate of extraction and depletion of non-renewable resources, most of the focus shifted towards renewable sources of energy such as wind energy, solar energy, tidal energy, geothermal energy, and so forth. These renewable sources of energy have made it possible for distribution of electricity in remote areas as a solar panel that converts the solar energy to electrical energy can be set up independently.
[004] However, these renewable sources of energy are not reliable as they depend upon natural activities. For example, power generated by solar panel in a rainy season is comparatively lower than energy generated in a summer season. Also, in a present-day of a world, an uninterrupted supply of electricity is much needed, and to achieve it, inverters are installed that switches to an optimal source of the electricity. Conventional inverters can switch between two sources of power supply and if both of the power supplies fail, leads to shut down and blackout. Additionally, the conventional inverters also lack a facility of remote monitoring, controlling, and analysis.
[005] There is thus a need for an uninterruptible power supply system that can supply a continuous power to loads in a more efficient manner.

[0056] At the step 310, the system 100 may receive the level of battery measured by the second battery level indicator 124 of the inverter 118.
[0057] At step 312, the system 100 may compare the measured level of battery with the pre-defined level of battery. If the measured level of battery is greater than the pre-defined level of battery, then the method 300 may proceed to a step 314, else the method 300 may proceed to a step 316.
[0058] At the step 314, the system 100 may supply the power to the load 102 from the inverter 118.
[0059] At the step 316, the system 100 may actuate the diesel generator 120 to supply the power to the load 102.
[0060] While the invention has been described in connection with what is presently considered to be the most practical and various embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
[0061] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined in the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements within substantial differences from the literal languages of the claims.
