These are high quality submersible solar pumps that can transfer water over great distances or up hills. Power directly from low voltage solar panels, these pumps offer a cost effective solution for remote water distribution. Suitable for off grid living, use with solar panels and/or battery banks, the quality brushless motor will perform for a range of power inputs. Great for the supply of drinking water to homes and to cattle in fields. With the capacity to pump up to 115m vertically, these units have a place on every farm.
Ideal for livestock watering or the supply of domestic drinking water, these are quality DC brushless motor water pumps are sure to impress. Popular for use in existing water bores and wells as their small diameter, only 76mm fits most configurations.
These are a submersible water pump which means these rely on their submersion in water to keep them cool and operating continuously. They are not suitable for out of water continuous operation.
Two models are on offer, the 24V unit which accepts power input directly from solar panels in the 18-48V range. This pump has a 300W brushless motor with a motor life in excess of 18,000hrs.
The 48V unit comes with a larger 600W motor and accepts input voltages in the 36-96V range. The larger motor means this pump can move more water greater distances.
The pumps feature a inner controller and MPPT to optimise there performance when connected directly to solar panels. The controller includes a soft start function to prevent pump cycling in low light conditions. Included is under voltage and over voltage protection along with thermal protection. If the pump is to shutdown in a protection state, it will automatically restart when the voltage or thermal conditions are right again.
If you have remote paddocks and don't want the hassle of a battery bank, connect the pump directly to your solar panel and let it operate itself when the sun is shinning.
As a guide, you will need 1.5-2 times the pumps motor rating to power the pump at the rated flow conditions.
SPBHP24 - 300W
For example, the SPBHP24 has a 300W motor, so users should consider 450-600W of solar panels to pump 1,000L/hr to a 50m elevation.
There are a range of methods to power this pump directly from solar panels;
Option 1 - 600W (4 x 150W panels)
Wire 2 x 18V, 150W panels in series to give 300W of power at 36V. Repeat this wiring on a second set of panels. Now wire the 2 banks in parallel to provide 600W of power at 36V directly to the pump.
Option 2 - 800W (4 x 200W panels)
Wire 2 x 18V, 200W panels in series to give 400W of power at 36V. Repeat this wiring on a second set of panels. Now wire the 2 banks in parallel to provide 800W of power at 36V directly to the pump.
SPBHP48 - 600W
For the SPBHP48, the motor is larger at 600W, so users should plan for 900-1,200W of panels to achieve 1,000 L/hr at 85m elevation.
This model can accept input voltages ranged 36-96V. So powering directly from solar panels can be achieved via;
Option 1 - 1200W (6 x 200W panels)
Wire 3 x 18v, 200W panels in series to give 600W of power at 54V. Repeat this wiring on a second set of panels. Now wire the 2 banks in parallel to provide 1200W of power at 54V directly to the pump.
Option 2 - 1200W (8 x 150w panels)
Wire 4 x 18v, 150W panels in series to give 600W of power at 72V. Repeat this wiring on a second set of panels. Now wire the 2 banks in parallel to provide 1200W of power at 72V directly to the pump.
Option 3 - 1500W (10 x 150W panels)
Wire 5 x 18v, 150W panels in series to give 750W of power at 90V. Repeat this wiring on a second set of panels. Now wire the 2 banks in parallel to provide 1500W of power at 90V directly to the pump.
These pumps will flow up to 2,000L/hr. The flow rate will drop to 1,000L/hr at the rated lift as detailed in the specifications below.
The pumps can exceed their rated capacities and still flow up to their maximum lift values as per the specifications table below. Flow rates will drop as you approach the maximum lift so consider this when selecting your pump.
To convert discharge elevation into pressure, users should multiply by gravity (9.8) and water density (1000kg/m3) to get the pressure in Pa, divide by 1000 for kPa. For example, for a maximum lift of 115m, users should expect ~1,127 kPa discharge pressure or 163 psi.
