-> Do I have to wire the inverter output to an isolated circuit for the device
-> want to power?

Basically, yes. The circuit doesn't *always* have to be isolated from
the mains, but it must certainly be isolated when it is connected to
the inverter. Rules in different jurisdications vary a bit, but
basically there has to be a switching arrangement that makes certain
that nothing is connected to the mains and to the inverter at the same
time.

The safe, simple way to do it is to have a completely separate circuit
that receives power from the inverter and never from the mains. Just
plug your device into whichever you want to use.

Thanks! Makes sense.
Next step is to decide how much of my limited budget to spend, how much I can
power with that amount of investment, and what to power.

A lighting circuit?
The PC's? (makes a nice UPS I suppose)

If you don't live off-grid, making electricity yourself, especially PV solar is
spectacularly stupid and expensive.

Spend the money on insulation and a car with good mpg and you'll be being far
'kinder to the planet'.
