By 1910- majority of windmills were Australian made,

reverse engineered from American units

polly pipe/ Late 30s

Post WW2 adoption

- 4 pole 3 phase motor

-Reaqua solar drive

-Can blend solar and generator seamlessly

-Full pressure control

-( constant pressure ect….)

OLD AND NEW

4KW SOLAR DC PUMP SYSTEM

CASE STUDY EXAMPLE

Location: Barkly Tablelands, NT

Controller: Lorentz PS2-4000 HRE32

Pumping: 50,000 litres per day

Head: 80m head.

- This system was 1 of 8 installed

- Installed to provide water for livestock and to pump to storage tanks.

- The Lorentz Pump Scanner app provides customers with real-time and historic data.

- A simple 3 click setup.

- Full Diagnostic

- Pressure control

- Battery mode

-

PUMP SCANNER

- “Low Yield” Bores ( 1000

L/HR)

-PS2 -150-1800 pump systems

-

-24 hr operation

-Full control and battery protection

BATTERY SYSTEMS

CONSTANT PRESSURE SYSTEMS

1. L/Ps is not the main concern , only in regards to yield.

2. Number of animals and storage volume is king.

3.Pipe line runs and lay out are important

4. With double hung floats and pressure control , the system sorts its self.

The main limits are

10-12 hrs pumping on solar per day 70-84 hrs per week

Bore yield

Pipe friction/ pressure
