Yes, Generac's home standby generators output a low (under 5%) Total Harmonic Distortion "Pure Sine Wave", which is considered to be power with a THD of less than 6%. This can safely power sensitive electronics. See the What Is Total Harmonic Distortion (THD)? article for more information.
Note: Generator spec sheets will list low (below 5%) THD generators as having TruePower™ Electrical Technology. See What is TruePower™ Technology? for more information.
