MSW: Modified Square Wave or M. Sine Wave Discussion (trimmed from original thread)
And off topic why do Americans continue to keep saying "if its a cheap MSW it most likely a square wave inverter"????
Because they are????
I am not sure what you are saying here... MSW = Modified Square Wave -- although the marking types like to call it a Modified Sine Wave -- which it really is not.
The Trace/Xantrex SW family was a different animal... Much closer to a True / Pure Sine Wave inverter output than most MSW types--but still did not meet the typically <5% Total Harmonic Distortion that is usually used as the cutoff point between "MSW" and "TSW" inverters. [correction: I looked up the specs. later in this thread and the "SW" family is rated for <5% THD--which in terms of electric power does meet the "True Sine Wave" definition--BB.]
Or are you just observing that the Yank's (not including the Canadian's, Mexico, and the rest of central/south America--eh?) are members of the Department of Redundancy Department?
