No.

Yes.

As a guide to how 'simple'it can be see eg

This is the solar grid tied inverter I mentioned earlier today.
I haven't looked at it in detail (a friend is interested in it) but it
probably addresses the mains driving problem.
A resistor is simpler.
And / or light bulb :-).
A spiral of suitably robust nichrome wire would probably allow enough
heat dissipation without a heat sink. Adding some blown air would help
greatly. I have dissipated hundreds of Watts in free air cooled coils
of Nichrome. .
