Down the track (lots of learning to do), I'm interested in creating and/or
working with alternative power sources (solar to battery then inverted to
mains power).

I know I'll probably buy a lot of the equipment for doing this, but it
always helps if you understand the circuit, especially when it stops
working.

So, if the input is 12VDC and the output is 240VAC, I suspect I'm going to
need to put a scope on both sides at some stage.

I'm just thinking ahead, and maybe I'll never need to look at mains through
the scope.

And even if I do, I may have bought a much better scope by then. Besides,
my research indicates that differential probes are specifically designed for
looking at high voltages (hence putting that question in my OP).

thx,
RR
