Did you know that you can run your borehole on both Solar and Wind power simultaneously? Take a look at the photo below for a successful wind and solar powered Installation designed to run same borehole pump. The pump installed is a special Grundfos SQFlex pumping system; a revolutionary concept in water supply designed to work using the two most basic sources of renewable energy available – the sun and the wind. Its unique feature is the flexibility to be powered by photovoltaic solar modules, a wind driven generator or a combination of both, and the motors are also designed for battery supply and AC generator power for standby operation, the power source being selected by simple switching.
At the heart of all SQFlex systems is the electronically controlled motor, which uses a sophisticated integral control module to accommodate variable voltage and frequency power inputs and also protects against abnormal operating conditions.
