DIY Arduino based MPPT solar charger controller. via electroniclovers

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
