Most solar panels and other alternative power systems
produce 48V DC or 24V DC. For a studio, it seems silly
that we have to buy an inverter that produces rather
non-clean AC (it's not a very pure sine wave) just so we
can then plug in a bunch of devices that have their
own AC-to-DC converters. You waste some power on the
DC -> AC -> DC conversion and end up with a less-than-clean
power supply, and possibly get noise in the audio signal
as a result. I always thought it would be better to
replace e.g. the computer's PS with a pure DC power supply,
and apparently somebody else thorught so too.
Someday I'll have a 100% pure DC studio. :)
BTW, "clean" inverters exist that do a pretty decent
sine wave, but you pay extra.
