LINK TO COMPLETE 11 SQF-2 KITS

The Grundfos SQFlex 11 SQF-2 Solar Submersible Pump is a versatile and efficient solution designed to meet diverse water pumping needs. Whether you require water for agricultural irrigation, livestock watering, or municipal water supply, this pump offers reliable performance powered by a range of energy sources.

Key Features:

• Versatile Power Options: Can be powered by solar panels, wind turbines, inverters, generators, batteries, or the utility grid. Compatible with any power source ranging from 30-300 VDC and 90-240 VAC.
• High Efficiency: Operates optimally with a series string of PV modules with a total peak power voltage over 30 volts. Efficiency is significantly higher at voltages over 100 VDC.
• Wide Range of Applications: Suitable for both high head and low head applications with helical rotor pumps (models 3, 6, and 11) and centrifugal pumps respectively.
• Built-in Protections: Features built-in safeguards against dry-running, overload, and overheating, ensuring long-lasting reliability.
• Warranty: Comes with a standard 2-year warranty from the date of purchase. An optional 5-year extended warranty is also available.

Optional Controls:

• CU202 Interface Box: Communicates with the pump and monitors operating conditions. Displays diagnostics, faults, dry-running status, operating status, power consumption, and water level switch input. The water level switch can turn off the pump when a tank is full.
• IO50 Control Box: Features cable terminations and a manual on/off switch. Ideal for interfacing between a solar array and the pump, allowing you to safely turn off the high voltage array during maintenance. (We don't carry this but can order.)
• IO101 Interface: Facilitates the use of AC backup for solar pumps. An automatic transfer switch disconnects the solar array when AC power from a generator, utility connection, or inverter is present. When AC power stops, it reconnects the solar array to continue pumping.
• IO102 Interface Unit: Designed for systems powered exclusively by a wind turbine or a combination of wind and PV sources.

Important Information:

The SQFlex pumps are not compatible with Ground Fault Circuit Interrupters (GFCI) in the supply circuit and should not be used in locations where a GFCI is required.
