Grundfos SQFlex 2.5-2 Solar Submersible Pump (Helical Rotor)

Product Description:

he compact 2.5-2 SQFlex submersible pump with helical rotor is designed for high-head, low-to-medium flow off-grid water supply applications. Operating on renewable energy sources like solar and wind power, the Grundfos SQFlex system delivers a highly reliable and maintenance-free water delivery solution.

Featuring an ultra-wide AC/DC voltage input and built-in Maximum Power Point Tracking (MPPT), the pump maximizes performance even during low sun exposure. The integrated MSF motor provides full electronic protection against dry-running, over/under-voltage, and thermal overload.
