<p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'>I agree
with Brian and Mark on most of their comments, but here’s a bit more:<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'>Mark is
right, there’s no way to separately control filling two tanks at
different levels. I didn’t read that section very carefully.
Brian’s float valve approach and sequential filling is about the only
approach. But given that a float valve failure could be catastrophic (5,000
gallons flowing back down) you might want to add a check valve on the line to
the higher tank, if the line from the well to the two tanks is shared.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'>Remember,
too, that the total dynamic head is measured from the water level in the well,
not the pump level. That means your tdh on the far well is something less than
220’, or about 97 psi (plus friction head). Assuming you don’t have
3,000 feet of signal cable in the ground, the P2Flow approach would likely work
well. Their 0-100psi transducer has a resolution of 0.1 psi. Make sure to add a
check valve where the line leaves the well, so as to be unaffected by
fluctuations of the water level in the well, and put the pressure-sensing
transducer after the check valve, so that it only measures head determined by
the tank level. We’re working with a similar application here in New
Mexico, so I’m learning this too.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:black'>One
respectful disagreement with Mark: The 3SQF-3 Grundfos is officially rated to
656’. I hear it will do well more than that, but no direct experience. I
would not recommend the Lorentz after multiple failures back when Dankoff (now
Conergy) was the sole North American distributor. (We are in Santa Fe so do
will call pickups for most orders. Don’t ask me to describe seeing
pallets of junk Lorentz pumps outside their warehouse, waiting to head to the
recycler.)<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>I don’t know how the
two tanks are laid out physically, but if they happen to be installed in a way
that you could run one pipeline up to the tank at 200’ and go from there
to the other tank, you might try using a float valve in the lower tank and a
float switch in the upper tank. The lower tank’s inlet would just be
“teed” off of the pipeline going to the upper tank. The lower tank
will fill first, being the path of least resistance. When it is full, the float
valve closes sending water through the pipeline to the upper tank. When the
upper tank is full, the float switch would turn the pump off.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;

<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>The distance to the float
switch in the upper tank is a bit far, but you should be OK if you use a larger
gauge wire than usual. I think that 18 gauge would be fine, but 16 gauge would
be better. If it is line-of-site, you might look into doing a wireless control
, but that would mean that you need a small PV module and a battery up there.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>As to Allen’s comment
about array size, he is correct about the pump drawing a max of 900W. However,
if you only put a 900W array on the pump, it will only pump at max volume at
mid-day. If you put a larger array on the pump, the array will produce 900W in
less light (morning and afternoon) and produce a lot more gallons per day
(GPD). The GPM figure of a solar pump is really only relevant for making sure
that you don’t over pump a low yielding well. It’s really GPD that
counts. That 1.36kW array might produce 900W at 9AM and 3PM, giving you a solid
six hours of max output pumping. No problem over sizing the array – the
pump will only draw what it needs. If you have really good exposure to the sky,
you can use a tracker to increase GPD instead of over sizing the PV.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>According to my info, with
250” of head (220’ plus pipe friction loss) you can get about 2000
GPD (summer) with the Grundfos model 6 SQF-2 and about 700W of PV in a fixed
array, with a peak flow of 4.5 GPM. Adding more PV will give you more GPD. With
the model 11 SQF-2, you can get up to about 4300 GPD with a 1750W array at that
head. If you needed even more water volume, and the well produced it, you could
even put two pumps in the well (with separate arrays). I had one dealer who
managed to put two Grundfos pumps down a 5” casing! He said that it all
went easy….but I don’t believe him. He did have a curious issue
though. He said that if he turned one pump off with its CU200, both pumps would
shut down, even though the other pump was not connected to that CU200. He
couldn’t just run one pump. I never did talk to Grundfos about that.<o:p></o:p></span></p>

software is a lifesaver and FREE! Not to contradict Allan, but I do not

far—they usually recommend a max distance of 1600’ for the float
switches. Lastly, if you are ever worried about the head, the Lorentz

<p class=MsoNormal style='margin-left:.5in'><span style='color:black'>You can
get Grundfos’ WINCaps software from your RE or pump supplier; some will
run the sizing for you (Jeremy at Conergy does for us). I didn’t check
your head and flow, but I would expect that’s about your only good pump
choice at that head. Add a tracker if you need greater summer output;
don’t attempt batteries as a solution. If usage occasionally exceeds
output, add an IO101 control and allow the pump to run off any AC source at
night. A tiny 1,200W inverter/generator will work at sea level. Use a CU200
controller to allow a float or level detector switch to turn off the pump when
tanks are full. Mercury-based float switches last longer in signal circuits
that carry no current. If you can’t use a float switch because the lines
are already buried, look into <a href="http://www.p2flow.com/">www.P2Flow.com</a>
for pressure transducer-based control. Read the website info, then call Britt
there with your specific application. That array sounds oversized, as the pump
draws a maximum of 900 watts. Hope this helps.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'>We normally don't do solar water
pumping but a friend asked for some help designing his system. He has one
well and two 5,000 gallon reservoirs to fill up. The average usage is
expected to be about 2,000 gallons per day but may be higher in the summer.
The tanks will have level detector switches to sense when the tank is
full. The site is near Leesburg, VA.<o:p></o:p></p>

<p class=MsoNormal style='margin-left:.5in'>The problem is to design a control
system to turn on the pump when one or both of the tanks needs water and to
shut it off when both are full. The closest tank has a head
requirement of 200 feet (pump to tank) and is 300 feet from the well
head. The second tank head requirement is 220 feet and it is 3,000
feet from the well. The pipes are expected to be 1.25 or 1.5 inch.<o:p></o:p></p>

<p class=MsoNormal style='margin-left:.5in'>A Grundfos SQFlex 6 SQF-2 pump with
1.36 KW solar was recommended, 360 foot head, 360 gph. I think that this
would provide the lift but not the quantity. Hmmmm, what valves and
controls would you all suggest?<o:p></o:p></p>
