Is Modified sinewave are equal to Square wave UPS?

Is Modified sinewave are equal to Square wave UPS? now pure sinewave are popular in the market, can adapt to all loads. so can anybody tell me when choosing UPS the wave form Must Be Considered ??

There are three major types of loads: Resistive load (Lamps); SPS load (PC power supply) & Conductive Load (Motors). All the types of load can be used with pure sine wave. However, only Resistive and SPS loads can be used with modified sine wave.

BTW: I've never seen a 50kVA-ups with square wave output voltage, did you? :-)
2nd BTW: This a group for professionals, really?

Micheal Houston • agree more. now in the market, there will be less and less square wave in the market, all are pure sine wave now, as you know, some loads very easy damage by square wave inverter or UPS, if you use a square wave with a TV or stereo equipment, the sound quality is poor , if with a motor there will be a beep sound happens, that's mean your electrical equipment are die young!! your appliance is suffering chronic suicide!! so think about this, Avoid unnecessary loss is your choice!
