The main objective of this project is to provide uninterrupted power supply to a load by automatically selecting optimum power from any of the 4 different sources, such as solar, mains, generator and inverterto ensure continuity in the power supply.

In this project ,four switches are used in place of four different sources of power supply.When any of the switch is pressed it shows the absence of that particular source These switches are connected as input signals to the microcontroller of the 8051 family. The output ofthemicrocontroller is given to a relay-driver IC that switches appropriate relay to maintain anuninterrupted supply to theload.

The output is observed by using a lamp drawing power supply from the mains, initially for all the four sources. On the failure of the mains supply (which is actuated by pressing the appropriate switch), the load gets supply from the next available source, for instance, an inverter. If theinverter also fails, it switches over to the next available source, and so on.

The current status, as to which source supplies tothe load is also displayed on the LCD.As it is not feasible to provide all 4 different sources of supply, one source with alternate switches are provided to get the same function. However if 4 sources are available it can be modified to take power from them.


This project can be further enhanced by using other sources like wind power, and thentakes into consideration the best possible power source whose tariff remains lowest at that moment.

Q & A
Q:  What is the concept behind this project?
A:  The concept is controlling charging of capacitors using a timer in astable mode.
Q:  What is the family of microcontroller is used?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  Can the lamp be replaced by any other load?
A:  Yes, any load with rating up to 200W can replace the lamp.
Q:  Does this project work on different supplies?
A:  We don’t supply all four sources of supply in the project but only one source with 4 relays which are capable of taking supply from 4 different sources. So you can use any other 3 sources if available at your end. Please watch the video carefully.

I got to know about edgefx through internet. I was searching my project title in google then i got to know about edgefx website. So, i have directly visited the website.
I have decided to buy project from edgefx because i found my project in edgefx website. I like most about edgefx kit was the audio visuals.
the kit was delivered with right components.
the supporting executives has helped me in purchasing the projects
