<p>The problem I had with Snap N rack pipe systems is they really
can't take any uplift; which is not a good thing in Haiti during a
hurricane. Those little pinch screws just are not enough. I would
look at other systems. The one you built in Mynamar looks pretty
good.<br>

<div>Hi Jason,</div>
<div><br>
</div>
<div>
<div>For the past few years I've been helping build
mini-grids in rural Myanmar, where flooding is a regular
occurrence in many villages. </div>
<div><br>
</div>
<div>For one village that floods every year, we specified
reinforced concrete posts under the feet of standard
ground-mount racks, and also to elevate the power house
with batteries and electronics. It works well and was a
good fit for that project. See the attached photo. They
mixed the concrete on-site using locally available sand,
gravel, water and labor.</div>
</div>
<div>Check out more photos here:</div>

<div>For a big system here in the USA I would look at the
SnapNrack series 200, as others have suggested, set atop
tall concrete posts. The vertical 1.5" galv pipe legs
would go all the way from below grade to the top as the
steel reinforcing inside what are basically very tall
concrete footings. I'd think 10 or 12" diameter round
"sonotube" forms set down below grade as much as the soil
conditions require/allow. Use a concrete pumper truck to
fill all the tubes with concrete. SnapNrack may have
already done the engineering for this type of thing...<br>
