Benn - Thank you!<br>
<br>
I did intuitively notice in watching the assembly videos that that after
the initial tensioning of the anchor cable that there was only minimal
attention (and hardware) devoted to keeping that cable under tension.
Could be as simple as a ratcheting device to periodically tighten up
after install perhaps? Doesn't seem like that would be too hard to
retrofit.<br>
<br>
I do see you are in the plains up there in Canada - so wondering perhaps
the winds are much higher - still it shouldn't move a cm after install!<br>
<br>
Thanks again - very valuable feedback. Sorry you had hassles!<br>
<br>
Best,<br>
<br>
Jeff<br>

together fairly well, however the cable anchor system, while seemingly
slick, left much to be desired in my experiences. </div><div dir="auto">Some
anchors would not come close to the required load test pull-out values,
requiring extra anchors to be needed, which is fine, until all the
anchor holes have been used. The anchors don\u2019t \u201csecurely\u201d hold the rack
down, meaning it leaves a bit of room for movement, so under high wind,
and over time it can wiggle and loosen the anchors leaving more and more
room for movement each time. That said, they do recommend rechecking
the anchors after some time, but this can be an issue for some sites. </div><div

racks on either side) had shifted forward about 25cm, seemingly due to
high wind. It drove the front anchor base plates into the ground and
caused some damage to the rack structure which had a design flaw that I
believe was corrected. </div><div dir="auto"><br></div><div dir="auto">They
recommend re checking the pull-out load testing of the anchors after a

been over a year and a half since the last one I worked on so it\u2019s not

the rack/rail assembly and mounting modules, issues with the mod mud/end
clamps. </div><div dir="auto"><br></div><div dir="auto">I\u2019m not

Wow cool
product Nick! Anyone have actual
experience? <br>
<br>
I've been thinking that the concrete beam systems (above grade
pre-engineered rectangular blocks like solarmounts.com) really could be
used for any ground mount rack system (Unirac, IronRidge, SnapNRack,
SolarMounts, ReadyRack, etc.) in other words many ground mount systems
could be bolted to an above grade concrete beam - would just need a sign
off on uplift by an engineer at the worst or just apply existing
engineering models. Many manufacturers already off that option and
probably provide the engineering.<br>
<br>
This might expand small system options for those manufacturers only
offering ballast systems to large system buyers.<br>
<br>
Which makes me think that If I tried a Nuance system and the soil didn't
work out for the cable pull you could then just bolt them down to a
concrete beam system as a plan b.<br>
<br>
Thoughts? Experience anyone?<br>

Mac,<div class=""><br class=""></div><div class="">I recently have been
investigating the use of <a href="https://nuanceenergy.com/" class=""
moz-do-not-send="true">Nuance\u2019s Osprey</a> product solution. Doesn\u2019t
necessarily fall under the ballasted category and since you\u2019re trying to
avoid the heat pump lines it may not fit your strategy either but I
really like the option of getting away from pouring concrete. The
anchors are set 40-65\u201d deep. For smaller projects it seems like the cost
may be somewhat prohibitive due to shipping logistics but appears like
they price out affordably once you purchase a bit of specialized
equipment and get around the freight costs.</div><div class=""><br
