How about Soladeck? They have the din rail for breakers or fuseholders and
are clearly for mounting at the roof slope. And they are UL approved.

Thank you all for the ideas and infoin many parts of Oregon you are

A NEMA 3R box can be mounted vertically on a sloping roof by
attaching brackets to the sides of the box and leveling the box. The
bracket or L-foot can allow the box to swivel to vertical.

We've made up mounting brackets with
unistrut for this purpose as well. We just bend their regular 45
deg angle brackets to match the roof tilt. It's a bit of work
though, so we are going to other solutions like the Soladek, or

Wrenches,
On a recent install I've come across a question I would like to get your
thoughts on.
In regards to running a GEC on a "separately derived power system", more
specifically A single phase 600 v residential PV system with a string inverter.
>From my past experience and building from
W:
A string inverter does not constitute a separately derived system unless it is
transformer isolated. The recreating of the neutral is what creates an SDS.
Your GEC, if required, stops at the inverter. It is not always required, i.e.
Enphase M250.

William is correct, a PV System is NOT a SDS.
If you're installing a "TL" or transformerless string inverter, a DC GEC
from the inverter is NOT required, only a properly sized EGC.
With Micro-inverters, if the PV+ or PV- has a ground reference in the
micro-inverter, such as an Enpha
Eaton/Cutler Hammer now has a line of 600V and 1000V disconnects available
that make life easier for us. (No, I'm not hyping for Eaton.)
When used in max 600V DC applications, you can now use a single disconnect
(30A to 400A) to disconnect multiple source circuits, one source circuit per
