Answer to Question 1

The MPPT starts by setting a load value and measuring the module output voltage V1 and the current. The power (P1) at V1 is calculated. Next, the load is increased and power is calculated at several points until it is less than the power calculated at the previous point, indicating that the MMP has been passed. At this point, the MPPT reverses back to the previous voltage and then goes back and forth (oscillates) between the two voltages on either side of the MPP.

Answer to Question 2

The low pass filter removes residual harmonics from the sine wave output.
