Our Technology

Engineered Systems. Proven Components. Built for Australian Conditions.

At Outback Solar Pumps, technology isn’t about buzzwords or headline features — it’s about delivering reliable water in harsh, real-world Australian conditions. Extreme heat, dust, long run times, variable sunlight, and remote locations demand systems that are properly engineered, conservatively rated, and built to last.

Every Outback system is designed as a complete, balanced solution. Rather than selling individual components in isolation, we carefully match high-quality submersible pumps, intelligent MPPT controllers, and premium solar panels so they operate efficiently and safely together. This integrated approach reduces electrical stress, improves day-to-day performance, and significantly extends service life.

The result is a solar pumping system engineered to work as a whole — not just on paper, but in the field. Fewer failures, lower ongoing maintenance, and dependable water supply where reliability matters most.

Our focus is simple: stable performance, long service life, and minimal maintenance — even in remote locations where failure isn’t an option.

Water-Filled Submersible Pump Technology

Built for Continuous Duty and Long Service Life

All Outback Solar Pumps use water-filled submersible DC motors with integrated thrust bearings. We do not use oil-filled motors. Water-filled motor technology is specifically suited to solar pumping applications where long daily run times, fluctuating power input, and high ambient temperatures are common.

By using water as the cooling medium, heat is dissipated more efficiently, helping maintain stable operating temperatures and reducing thermal stress during extended operation. Integrated thrust bearings are designed to handle the axial loads generated by multi-stage pump impellers, improving mechanical stability and extending service life.

Unlike oil-filled designs, water-filled motors eliminate the risk of oil breakdown, expansion, or contamination, making them a safer and more reliable choice for bore, livestock, and remote water supply systems. The result is consistent performance, reduced wear, and dependable long-term operation in harsh Australian conditions.

Why Water-Filled Motors Matter

  • Continuous Cooling Using the Pumped Water

  • Stable Operation During Long Daily Run Cycles

  • No Risk of Oil Degradation or Leakage

  • Environmentally Safe for Livestock and Potable Water

  • Consistent Performance in Hot Climates

Thrust Bearing Design

Designed to Handle Vertical Load Correctly

In submersible bore pumps, the greatest mechanical stress is not rotational — it is vertical. Multi-stage impellers generate significant axial force during operation, and if this load is not properly managed, it is transferred directly into the motor shaft, bearings, and seals. This is a common cause of premature wear and early failure in under-engineered pumping systems.

Outback Solar Pumps incorporate a dedicated thrust bearing system specifically designed to absorb and manage these vertical loads. By separating axial forces from radial shaft support, the thrust bearing maintains correct shaft alignment, reduces bearing wear, and prevents long-term mechanical fatigue. Upper and lower bearings provide stable rotational support, while the thrust bearing system handles continuous downward force generated during pumping.

This design approach is critical for solar pumping applications, where pumps often operate for long daily run times under variable loads. By correctly managing vertical forces, Outback Solar Pumps achieve smoother operation, improved efficiency, and significantly extended service life — even in deep bores and continuous-duty installations.

Intelligent Power Management for Solar Conditions

Every Outback Solar Pump kit includes a dedicated MPPT (Maximum Power Point Tracking) controller designed specifically for DC solar pumping.

AC/DC MPPT Controller Technology

Built Specifically for Solar Pumping

Every Outback Solar Pump system is supplied with a dedicated MPPT (Maximum Power Point Tracking) controller engineered specifically for DC solar pumping applications. Unlike generic motor drives or repurposed inverters, these controllers are designed to manage highly variable solar input while delivering stable, efficient power to the pump throughout the day.

The MPPT controller continuously monitors solar voltage and current, dynamically adjusting operation to extract the maximum available power from the solar array as conditions change. This allows the pump to start earlier in the day, operate longer through partial cloud cover, and maintain smoother performance during fluctuating sunlight — maximising daily water output without overloading the motor.

Integrated protection functions safeguard both the pump and the electrical system, including soft start control, dry-run protection, over-voltage and under-voltage limits, thermal protection, and fault monitoring. These features reduce mechanical and electrical stress, prevent damage during abnormal conditions, and significantly extend system service life.

Controller Benefits:

  • Higher Water Output During Low-Light Conditions

  • Smooth Motor Starts and Stops

  • Protection Against Dry-Run, Over-Current and Voltage Fluctuations

  • Improved System Efficiency Across Changing Sunlight Conditions

  • AC/DC input options for maximum benefit

Reliable Power, Day After Day

Outback Solar Pump kits are supplied with high-efficiency monocrystalline solar panels selected for durability and long-term output.

High-Efficiency Solar Panel Technology

Designed for Reliable Daily Water Production

Outback Solar Pumps systems are supplied with high-quality monocrystalline solar panels selected specifically for off-grid pumping applications. These panels are chosen not just for wattage, but for their ability to deliver consistent, usable power across a wide range of light conditions — from early morning and late afternoon operation through to variable cloud cover.

Monocrystalline cell technology provides higher efficiency and improved performance in low-light conditions compared to older polycrystalline designs. This allows Outback systems to start pumping earlier in the day and continue operating longer, increasing total daily water output without oversizing the array or stressing the pump.

All panels used in Outback Solar Pump kits feature robust aluminium frames, tempered glass construction, and weather-resistant encapsulation designed to withstand harsh Australian environments. High UV exposure, heat, dust, wind loading, and temperature cycling are accounted for to ensure long service life in remote and agricultural installations.
