Far more of an issue is synchronising the frequencies and putting crap
on
the local supply or even creating RFI from the inverter in my
experience,
which is not much here, but from those who rushed out and got it,
there
have been issues.. grin.

Drivel.
Grid tie inverters are relatively cheap because they don't have to
create
their own sine wave out of nothing.
They are more like an amplifier , input sinewave from the mains, so
perfect
sine wave and perfectly sychronised.


Harry..

Obtain an Oscilloscope then connect that to the output of any
transformer or even direct to the mains and observe the mains waveform..

A Perfick sine wave is the one thing you will not see;!...

And how exactly will you see how perfect or not perfect it is? Just
eyeball
it?
Heh heh, You are as bad as TurNiP

The only way to be absolutely sure is to get a piece of graph paper and
some
sine tables and draw your own.
And those tables were derived geometrically not by some stupid computer.
Similar geometry to that going on in an alternator.
And any non sinusiodal AC passed through inductors and capacitors,
gradually
gets to look more and more like a sine wave interestingly.




.

There are lot of distortions on the mains waveform.


Answer this question if you will. Have you got an Oscilloscope or not?..

No.
