<br>
Yes we were one of the early adopters and installed a 32 KW Nuance
system last year in CA.<br>
<br>
Mixed results though I think it's a very exciting concept and believe in
it going forward - they are working out the bugs.<br>
<br>
The new version is much better execution as far as the above ground rack
goes than the first version - now ready for prime time. It's actually a
bit overkill now - but very solid.<span> they fixed the problem of
needing two hands for the end clips too I believe.<br>
<br>
The installation and then pull testing of the anchors can be
straightforward but there are some things to watch for:<br>
</span>
<ol>
<li>The first test tool they rented or sold to do pull testing was
highly problematic - they've fixed that and have a new tool but it is
very expensive - Luke (the lead designer) had one at RE+ in Las Vegas
last month - I highly suggest you speak with him and arrange to rent the
new tool to do the job - do NOT use the first one</li>
<li>They have a new wider anchor that needs to be installed before the
post platforms - do you have the wide ones or the original ones? The
wide ones are recommended in clay or any wet soil - refer to Luke on
that but with the narrow ones we need 2 or even 3 anchors per post in a
few wet areas we had.</li>
<li>As for your tool questions - we rented a 30 lb impact drill to
install the rods - though the dewalt one you show may work - I'd go
heavier if you have hard soils. That last tool you show may do the
trick - but for the $100 rental fee it was worth having the big 30 lb
impact drill from the rental shop.</li>
</ol>
<p>Make sure you have a chart or write in marker on the rack itself to
show the inspector all of the uplift figures you get. We were in the
1200-2000 lb range for most of our anchors - sometimes we needed 2 or 3
according to their formulae if one anchor doesn't pull enough
resistance.<br>
</p>
<p>Also make sure the chinese finger cable grips are fully pushed all
the way down. We went back after the first wind storm and made sure
they didn't move.<br>
</p>
<p>All has been great with the rack through two winds storms.<br>
</p>
<p>After many years of pouring concrete into sonotubes - and even after
some recent experience with ground screws - I think the ground anchors
are revolutionary! Just got to be installed correctly! I think it's a
winner going forward and Nuance - though a small company - I think is
doing a good job making it work.<br>
</p>
<p>Hope that helps,<br>

OSPREY PowerRack as a ground mount option that does not require an
excavator. I am wondering two things about it:</div><div><br></div><div>1.
Does anyone have experience with this, and do you like it?</div><div><br></div><div>2.
What drill do you use for the drive rod? </div><div><div>It seems like
the Milwaukee 2" SDS max drill is the standard - <a

am wondering if it is possible to use a cordless drill though. DeWalt
makes both a cordless and corded version that claim to have the same
impact energy as each other, although both are less than the Milwaukee
Drill. Milwaukee has 19.9 ft-lbs of energy and the DeWalt ones have 19.4
Joules, which is 14.3 ft-lbs of energy.</div><div>Cordless Kit - <a

cordless drill is tempting because I already have a bunch of DeWalt
equipment, and it would be nice to avoid needing a generator or some
very long extension cords.</div><div><br></div><div>Thanks!</div><div>-Dave</div><div><br></div><span
