In the December edition of PBO it was mentioned that cheap generators will produce a square wave rather than the pure sine wave associated with normal mains.
Now, I may be totally wrong but I cannot see how a rotating winding within a magnetic field can produce anything other than a sinusoidal waveform. It is true that the cheaper solid state inverters produce a square wave and they are not suitable for many types of electronic equipment but I have used my TPG 950 from B& Q (£65) to power my Hi Fi with no problems. Just to check my theory I will attach an oscilloscope to the output via a Voltage dropper and look at the waveform.
