The most common mistake I've seen is not correctly using white/gray for
the grounded conductor on the DC side. I've seen errors most commonly with
positive grounded systems (SunPower) but often times installers use black
in place of white or something along those lines. It definitely gets
confusing
Does anyone have an one-line diagram for a grid-tie, battery back-up, for a
feed in tariff (in the TVA service area)? I have used a-c coupled in areas
where there is net-metering, but TVA requires that there is a separate
Generation meter, tied ahead for the service.

Hi Carl,
I'm glad you're making some progress. I've always had good luck following
the Schuco table for setting the expansion tank pressure. I would expect
the pressure in the expansion tank to be higher than the glycol charge
pressure under most fully charged circumstances. For example, if you
No wiring color convention or code requirement will reduce the need to
check (double-, triple-check) polarity during any DC wiring task. I'd
almost prefer everything to be black except the grounded conductor (white
if present) and grounding conductors in a DC system.
(opinions stated without consi
Sorry for my density..is "PV wire" necessarily double insulated?
Thanks,

Hi Dick;
What you're suggesting is actually something I thought would work too:
having totally odd colors that immediately said DC.
IT really would be the best, because if you go in with a meter set to
read AC, and show no voltage, then get your voltage sniffer out, and it
doesn't beep, you th
HI Ray,
I agree and think that at least high voltage DC should have its own color code.
Labels go away, but wire colors are forever.
thanks,
