Attaching SMA inverter to PV mounting pole [RE-wrenches]

[Brian Teitelbaum]

Bob,

Two suggestions:

1) Use the Wattsun Service Panel. It was designed for exactly what you want
to do. Here's a link:

e_panel.html


3) Instead of using, or making, a U-bolt with the Unistrut, use Unistrut's
(or Kindorf's) conduit clamps. Another link:

         http://www.unistrut.com/Browse/cat_detail.php?S=S06&P=P1109

The conduit clamps are used in a kind of reverse method: instead of using
the clamp to hold a conduit to something, like a wall, the clamp goes around
the pipe mast and holds a piece of strut to the pipe. The strut provides you
with a flat surface to mount enclosures to. Use two clamps and struts to
give you a top and bottom mounting point. MUCH better and nicer then
U-bolts!

Wrenches:

I am looking for an elegant way to attach an SMA inverter to a PV mounting
pole. The combiner box and the DC disconnect will probably also be on the
pole. Heretofore, we have used shallow Uni-Strut and a threaded rod bent
into a U-shape around the pole and attached together with nuts and washers.
It's OK, but I am looking for other options that may include a panel (large
enough for the inverter, combiner, and DC disconnect) and
strapping--something that does not look so industrial. The advantage of our
current method is that it is VERY stout.

Any great ideas or products?
