MAXIMUM POWER POINT TRACKING EFFICIENCY where P DC is the DC input power to the inverter and P M is the power at MPP
Total Harmonic Distortion Inverters for grid-<strong>connected</strong> <strong>PV</strong> systems must generate energy at a defined quality The standards (example: international Standard IEC 61000- 3-2 ) above require a THD of ≤ 5% for the harmonic spectra of the current waveform. nominal.
