This document proposes a design for an affordable and high-efficiency inverter. It aims to use low-cost components like the IC 4049 oscillator and transistors to convert DC voltage from a battery to AC voltage via a transformer. This design seeks to provide electricity for underprivileged people at a lower cost than other inverter technologies that use microcontrollers or multiple interconnected inverters. The proposed inverter would have low maintenance needs and occupy less space compared to alternative designs. It includes circuit diagrams and descriptions of the oscillator, transistors, transformer, and other components used to efficiently convert the battery voltage to a 230V AC output.

16. LITERATURE REVIEW
• According to paper[1] and paper[2] uses microcontroller, it is
high cost, difficult to assemble, Heavy weight, required more
components
• On the other hand paper [3], the 100’s of inverters are connected
to the main system via the LAN connection In this lot of Cables
are required, High Cost, Occupying more space, It need human
interaction for monitoring the inverters

17. CONCLUTION
 By this method underprivileged can get electricity during
mains off
 Less weight, maintenance free inverter it’s very useful in
