The Grundfos 15 sqf-290 can provide 20 gpm to 7.5 gpm at 197 feet to 492 feet respectively. These Grundfos SQFlex solar pumps are 2.5 hp and can be directly powered by solar or wind power or can be run on an inverter, a generator, a battery or the utility grid, or any combination of these sources. Virtually any source of power, 100-300 VDC and 90-240 VAC, can be used to run the pump. They can operate on a series string of PV modules with a total peak power voltage over 100 volts.

SQFlex submersible pumps have a 2 year warranty from the date of purchase. A 5 year extended warranty is available separately.

Specifications:

The 15 SQF-290 is a solar submersible pump designed for water supply from shallow wells, with low daily flow requirements. Because of its small size, it is a perfect match as a replacement pump for a wind-powered or hand-pump water supply, and the pump also excels as part of a battery system. This makes it the most competitive solar water supply solution on the market for these small-scale applications.
