Re: [RE-wrenches] Ground Mount with cable anchors

2019-09-10 Thread Benn Kilburn 
Glenn,
I've installed an 80+kW and a couple 10+kW systems using this Nuance
system.  They are assembled fairly quickly and the legs are adjustable for
uneven ground, which is nice.
The ease of driving the cable anchors into the ground will, of course,
depend on the site.  Luckily, i had no issue with rocks and the only real
issue i had driving the anchors was the driving rod separating once or
twice (due to the length of anchors for our location, we needed a 2-piece
driving rod).
Testing the (pull-out strength) anchors is a bit cumbersome and we have not
come up with a way of re-testing the front ones once the mods are
installed.  Make sure you use a scale that has a "max pull" feature to hold
the max pull-out strength otherwise the numbers are constantly moving and
difficult to read.
Hopefully they have added leg braces to the front legs where they are
needed more so than just on the back legs.  If they haven't, then i suggest
requesting them as the front legs *will* buckle under high wind from the
north.

I'm not convinced that they are a solid ground mount solution as the
cable-anchor system does allow for some movement so they will allow for the
full array/rack to shift and move, as i have seen on the 80kW system.

Wrenches/Glen
I know nuance, they must be trailered or crained into position, leveled on
site and cables are driven in and pre-loaded and cable locks installed. I
have there products around California along with the predecessor. Delivery
can be an issue and there team does the cables so that's something to
consider too. They are fast to install, pre-layout the conduit and drop and
very quickly you are up and running. We have also done there blasted
version with concrete blocks or even just 36" pin anchors
