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. 11 SQF-2 Pump Applications SQFlex pumps are designed for continuous & intermittent operation, and are ideally suited to… Residential : Villages, schools, hospitals, single-family houses, etc. Farms : Watering cattle, Irrigation of fields or greenhouses Surface water pumping : Water from ponds and lakes . Grundfos 11 SQF-2 Features Runs from either DC or AC power : 30V – 300V Built-in electronics make for simple installation Extremely reliable Low operating costs Dry-running protection Built-in motor protection High efficiency Built-in maximum power point tracking (MPPT) Wide voltage range Built-in sand shield .
