INTRODUCTION:
Solar energy is referred to as the energy that comes from the sun’s
rays. Solar energy is widely available today. We only need the right
instruments to capture the sun’s rays and convert those rays into
energy.
Solar panels is a larger photovoltaic system to generate and supply
electricity. With a proper charge controller, the prospect of having to
pay 30-50% more up front for additional solar panels makes the
MPPT controller very attractive.
For AC loads, Such loads are fed by inverters, it’s essential that
output voltage of the inverters is so controlled as to fulfill the
requirements of AC loads.
The excess power generated by panel can also be shared by
auto-switching.

STEP-1 Initialize LCD and Microcontroller
STEP-2 Take input from solar panel
STEP-3 Use MPPT circuit to boost input power
STEP-4 Check the battery condition whether to charge or
discharge the battery.
STEP-5 Battery input is given to inverter which converts DC
to AC using center tap transformer.
STEP-6 Sensing circuit is used to determine if home load is
in use
STEP-7 Microcontroller is used to switch on relay using
sensing circuit
STEP-8 The LCD display that how much power is used by
load
