2. ABSTRACT:
 A solar inverter helps in converting the DC to AC with help of solar power and it helps
devices that run on DC power to run in AC power so that the user makes use of the AC
power.
 The main aim of this project is to make an inverter by using Renewable energy with the
help of solar panel for household loads.
 In this project we design a inverter by solar panel using the battery
 We aims to present solar inverter using power NPN transistor
 This power efficient inverter can be used to power up devices such as mobile charger,
LED lights etc.

5. CIRCUIT EXPLAIN:
 The timer IC555 is used as switching pules oscillator and it is the main part in this
circuit, IC555 configured as astable multivibrator to give continuous switching
pulse,two switching transistor TIP41A(NPN) and TIP42A (PNP) drive the transformer
T1 according to the pulse input at the base
 The transformer T1 is 230V Primary to 9V secondary but connected in reverse,so it can
react as step up transformer
 We can apply +5v to 15v DC bias to this circuit and get 110V to 230V AC With 50Hz
to 60Hz frequency but output may not pure sine wave as the PWM inverter output, it
gives only pulsated Ac

6. OPERATING PRINCIPLE:
INVERTER:
 The basics function of inverter is to convert DC power into AC power ,while at the
same time regulating the voltage,current and frequency of the signal
TRANSFORMER:
 The main principle of operation of a transformer is mutual inductance between two
circuit which is linked by a common magnetic flux
SOLAR PANEL:
 A solar panel is a device that directly converts the energy of light into electrical
energy through the photovoltaic effect
