# ARDUINO BASED MPPT SOLAR CHARGE CONTROLLER

what is Mppt( Maximum power point tracking) ?
“we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions”
How MPPT works  ? Why 150W solar panel does not equal to 150 w?

For example you bought a new solar panel from the market which puts out 7 amps. under charge the setting of a battery is configured to 12 volts : 7 amps times 12 volts = 84w (P=V*I) You lost over 66 watts – but you paid for 150 watts. That 66 watts is not going anywhere, but it,s due to the poor match of the solar output current and battery voltage .

After using MPPT algorithm we can get the Maximum available power

Battery gets is now 12 amps at 12 volts

Output power is equal to p= V*I p=12*12=144w
Now you still have almost 144 watts, and everyone is happy.
Specification of the project
1.This project is Based on MPPT(Maximum power point tracker) algorithm
2. LED indication to show the low mid and high level of charge stat
3. LCD (20×4 character ) display for displaying power,current,voltages etc
4. Lightning /Over voltage Protection
5.  Protection For Reverse power flow
6. Over load & Short Circuit protection
7. Logging data through WiFi
Electrical specifications :
1.Rated Voltage= 12V
2.Maximum input current = 5A
4. In put Voltage = Solar panel 12 to 24V
5.power of Solar panel  = 50 Watts
