Another option to an invertor is to run the panels in series, producing eg 120v etc. If you had enough panels to do this there would be no point using an invertor.

Grid tie inverters run the panels in series anyway - the inverters
normally take 600VDC input, depending how many panels you have.

(That's why fire brigades won't enter houses with solar panels to
put fires out.)


Pretty stupid really.
A 240V AC supply can have about 350V peak on it which is only a bit less
than 10 solar panels in series would be operating at.
Any more than 10 panels would probably be two strings and be less than that.
