What is the 2nd harmonic also referred to?

Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic.

Which generators have the lowest THD rating?

The A-iPower SUA10000EC provides 10,000 watts of starting power and 8,200 watts of running power. It’s perfect for the construction job site or as backup power for your home during emergencies. The generator features Pure Sine Wave Technology with less than 5 percent THD (total harmonic distortion).

What is an acceptable THD for a generator?

The harmonic distortion in conventional generators is generally in the range of 9–10%. For some generators, it can be even higher than that (manufacturers will often say “under 25%”, as it also depends on the load).

What’s the difference between inverter generator?

The main technical difference between inverter generators and conventional generators is what kind of electricity is produced. Conventional generators only produce AC electricity while an inverter generator produces electricity in 3 phases (high frequency AC to DC back to a stable AC current).
