I just finished a 7-day test of this pump and it performs exactly as the specified on the data sheet. Our delta h is about 140 feet and the pump transferred 5 rpm at that head.
The unit is quiet, starts early in the day and pumps late into the evening. It makes a convenient installation which is on a portable trailer so we can move it between locations as required. The rest of the system consists of 2 180 watt panels by Suntech and a LCB supplied by Dankoff. Combiner box is by Midnite.
We are very happy with this pump.
