Borehole Pump Power in the Kalahari

Borehole Pump Power in the Kalahari

In The Central Kalahari, a cattle farmer with 300 head of cattle had an existing 3 phase/ 5.5 kvA borehole pump.

For this installation, Specialized Solar Systems(SSS) opted to keep the existing pump due to the volume of water that was required daily and the depth of the Borehole which was 260m.

SSS designed and installed an off-grid 3 phase system with a variable speed drive controller, 10Kw panel array that included 40 x 250-watt solar panels.  20 of these solar panels were laid out in series and 2 strings,  paralleled out to give an open circuit voltage of 750 Volts.

On the same Farm, SSS also installed the Lorentz PS600 surface pump with batteries and panels to fill the existing cattle troughs with water from the reservoir.
