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;!...
