in Solar Water Pumping #1
hi,
this pump works from 30v.d.c to 150v.d.c and also on a.c..
if anyone has experience with this pump, does it work better with higher voltage or does it make a differance. the wires from the proposed solar array is 425'. i was thinking of using 4, 100 watt, 12v panels at 48v.d.c.. this may be obvious to some of you ,but i am a slow learner
thanks
charlie
