The THD mirrors the inverter’s capability to regulate harmonic distortion and the maximum amount of harmonic distortion it could potentially output. However, beyond the hardware and software/algorithm configurations of the inverter, various external factors can negatively impact the inverter's performance and bring about harmonic distortion.
Choosing a solar inverter with low total harmonic distortion (THD) lays the groundwork for maintaining the overall harmonic distortion at an ideal level. It is wise to be aware that investing in a quality inverter means lower risks of potential damage to connected loads.
Simply put, harmonic distortion in solar inverters refers to the deviation from the ideal sinusoidal waveform of the electrical voltage and current output by the inverters.
Its ITHD is usually small and negligible as compared to a harmonics-producing load such as a variable speed drive (ITHD for a typical 6-pulse drive ranges between 30% – 50%). Typically, one will find a Current Total Harmonic Distortion of 3% stated in the datasheet for a quality-brand inverter, as seen here.
