No, what is being marketed is a "Modified Square Wave" inverter.

The ignorant can be forgiven.

The shyster wants you to believe that you are buying a better inverter
than it really is.

Buyer beware.

No doubt you are correct....

But a "modified sine wave" inverter is a way for someone to tell you that
you are buying a device which doesn't put out a proper sine wave... rather
one which consists of an approximate sinusoidal curve made up from square
bits...

So it's not a modified sine wave, but rather a near sine wave with lots of
edges... Inferior in every way (but price) to a real sine wave inverter...

There are 2 main invertor options, sine or modified sine, which is IRL
rectangular wave. IIRC, iron fl ballasts and motors can overheat on
MSW, so all your apps ideally want sine. However MSW is much cheaper,
and there are workarounds. Fl lights can be run at just slightly
reduced power, or heatsinks added to the ballasts, etc. Electronic
ballast lights would run happily on 150v dc. Motor driven tools would
be fine as is unless youre running them to where they already get
seriously hot, ie heavy use. There are ways round it if it proves to be
an issue.

Small point.

Why would anybody modify a sine wave?

When people try to sell a "Modified Sine wave" inverter they are either
ignorant or shysters.
