Description
This is the Grundfos SQFlex Submersible Solar Pump : 11 SQF-2
Grundfos SQFlex Submersible Pumps offer the basis for a complete off-grid water supply system. Built with flexibility in mind, the 11 SQF-2 pump is able to run efficiently from either AC or DC power, and incorporates a built-in MPPT controller and soft-start. This model is a helical rotor pump, ideal when up to 120m (395′) of lift is required, and up to 52 L/min (13 Gal/min).
When the solar resource is unreliable, the Grundfos SQFlex pumps can be integrated with battery back-up systems.
