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

Solar PV submersible pump system fits 4" diameter wells and larger. The pump has only one moving part. Submersible pump controller is mounted above ground for easy access. and greatest reliability. The pump controller is weather sealed for extreme locations and climates.

This Grundfos SQFLex is an industry-leading submersible pump for water lifts of up to 800'. Advanced pumping 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. Virtually any source of power, 30 to 300 VDC and 90 to 240 VAC, can be used to run this submersible pump.

Grundfos pumps 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). Its motor is designed to draw a maximum of 8.4 A, which means that many types of PV modules can be used with this pump efficiently, including common 60 cell modules. SQFlex models 3SQF through 11SQF will fit into a 3" well and models 16SQF-10 through 60SQF3 will fit into a 4" well.

Eleven different pump models available can deliver from 82 gpm at 6' of head to 4 gpm at 800 feet. Use a 1.6 kW or smaller solar PV 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 highly efficient. Grundfos SQFlex has built-in protection from dry-running, overloading, and overheating to keep your system safe and sound.

Grundfos SQFlex pumps have a 2-year warranty from the date of purchase.
