I'm looking into getting a bigger Sun box (bigger

reading the specs... If I'm really going to do this, I'll need to get some
220v outlets wired up. (I'm in the US.) Any advice to pass along for this?
I'd much rather listen to other people's surprises than have to rediscover
them on my own.
Single-phase distribution is the US is officially 240V. 220V is
European (and other places).
If you're talking single-phase, it's not a big deal. Lots of people
with metal- or woodworking power tools have installed 240V shop wiring.
I even have a 50A 240V outlet wired in my own woodshop, just in case I
want to glom onto a big welder.
For 15-20A service, it's not really much different running wiring for
normal 120V service.
Where you get into the exotica is 3-phase service. There, you need a
cooperating utility and a deep pocketbook. Be prepared to be turned
down flat by your utility with the excuse that "We don't distribute 3
phase in your area".
There are always phase converters in that case; not cheap either.
