800 Foot Dynamic Head
4.1 GPM

This is a complete Solar PV Powered Water Pumping kit for 800 Foot Head up to 4.1 GPM. This Stand-Alone Solar Powered System uses Top Quality Grundfos Submersible Pumps.

This kit includes everything you need (except mounting post) such as Pump, pump controller, solar modules (panels), solar array mounting rack (top of pole), or Ground Mount, Float Switch and On/Off controller.

Intended for 4" Well Diameter.

Solar Water Pumping Kit Mode: SPS-1980

Solar PV Panel Power Rating: 1,980 Watts

Mounting: Ground Mount

Estimated Flow Rate in Summer: 1,890 Gallons Per Day (GPD)

Estimated Flow Rate in winter: 1,497 Gallons Per Day (GPD)

Maximum Flow Rate: 4.1 Gallons Per Minute (GPM)

Not included (but available through local suppliers) are the steel pole and concrete to support the solar array, (schedule 40 pipe, size and length specified in the rack instructions, drop pipe, water well safety rope (1/4") and wire.

This system fits 4" diameter wells and larger. The pump has only one moving part - no failure-prone diaphragms or motor brushes to replace. The controller is above ground for easy acess and greatest reliability. The controller is weather sealed for all climates.

This Grundfos SQFLex is an industry-leading submersible pump for water lifts of up to 800'. With the proper controller, SQFlex pumps can be directly powered by solar or wind or can be run on an inverter, a generator, a battery, the utility grid, or any combination of these sources. Virtually any source of power, 30 to 300 VDC and 90 to 240 VAC, can be used to run this pump. It can operate on a series string of PV modules with a total peak power voltage of at least 30 VDC, but its efficiency will be highest at voltages over 100 VDC (10% less efficient at 60 VDC, and 20% less efficient at 35 VDC).

Submersible pump designed to draw a maximum of 8.4 A, which means that many types of PV modules can be used with this pump efficiently. SQFlex models 3SQF through 11SQF will fit into a 3" well. Models 16SQF-10 through 60SQF3 will fit into a 4" well.

The 11 different pump models available can deliver from 82 gpm at 6' of head to 4 gpm at 800' with a 1.6 kW or smaller solar array. Use the helical rotor pumps (models 3, 6 and 11) for high head applications and centrifugal pumps (models 16, 25, 40, and 60) for low head applications for best efficiency. The SQFlex has built-in protection from dry-running, overloading, and overheating.

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