   Actually for system you don't really need inverters at all.  I use
12-volt compact florescent lamps, and 12 volt adapters are available for
laptops.  I use the lamps out in my yard, and my in-home 12-volt wiring
system is slowly growing.

Which definitely contains an inverter, thus, adding cost.

Which possibly also contains an inverter to convert 12 V to 17 V.

This is a good strategy if the 12 V system total cost is less than the
cost of more common 120 V (US) or 230 V (Europe) systems added with
the inverter cost.

My 120v inverter costs me 130-200 watts of power when the sun shines just to
be humming

   Actually, the 120 or 240 versions also contain electronics, which also
adds cost.  That said, the 12-volt bulbs do cost more, mainly because they
are a specialty item.

   Perhaps, but it would be an inverter sized for the specific job and would
only be on and taking power when plugged in, (which in the case of a laptop
could be rarely)

I do it mostly to avoid the 24/7 drain of a central inverter. (Yes, I know
that some inverters have power sensing, but they have their own issues.)
With or without the inverter, I would still want a separate, protected power
system, so that cost falls out of the equation.  The outdoor lighting part
of my wiring system is inexpensive because it uses common low-voltage Malibu
lighting cable that is made just for that purpose.  Inside my home I wire to
code, so the expense is comparable either way.  That leaves me with the
option of converting any circuit to mains power in the future..
