Interesting backyard water pumping project [RE-wrenches]

[Kurt Albershardt]

<x-flowed>

We upgraded a system feeding a waterfall with a Solar Force piston pump and 5x Siemens SP75 panels.  Pretty much everything else the original installer sold them was replaced or upgraded: inverter powered AC fountain pump replaced with a 12V Oasis, installed a DC timer and QO load center for all the DC.  C40 and the L16s died about a year later, so we put in an MPPT charge controller and large stack of AGM cells.  Inverter is still there on a manual switch in case they need to run a power tool 
out there.  Still running after ~6 years now.

Yes, I know that this is not the best use for power, but the world would be a sadder place without fountains, ponds, and water decorations. Instead of utility power I suggested using a solar powered DC direct drive pump, but he wants the water wheel to turn until 10pm. Any suggestions would be most 
welcome. Thanks in advance.
