7. Designed for Solar Water Pumping
Performance in High Temperature
Active power management to maximise pumping time in high temperatures
NO power derating up to 50°C ambient temperature, >50°C operation under reduced power

8. Designed for Solar Water Pumping
Performance in High Temperature
Active power management means when the temperatures get very high
We start active cooling
Where active cooling is not sufficient – slowly reduce power to find a working point
No urgent switch off
Water when it is most needed

9. Designed for Solar Water Pumping
Stainless steel housing with lockable door
Serviceability
Easy access front

10. Designed for Solar Water Pumping
More Water
Pumps are driven up to the hydrodynamic optimum
Max rpm > 54Hz means often 20% more water than any competitor
Fully backed by warranty
Because LORENTZ design solutions not components

14. Designed for Solar Water Pumping
Sun Sensor – extending your pump life
Calibrated module
Protects the pump from unnecessary running and start / stop cycles
Protects against over heating in low power situations
Which reduces the lifetime dramatically

15. Sun Sensor increasing pump lifetime
Voltage available, pump tries to start - Insufficient power pump can’t run
Enough power to start the pump - Insufficient speed to get water to the surface
On every failed start the NEMA coupling is worn, some controllers restart 60 times / hour
Motor is running without water flow – resulting in high temperatures

Switch on/off second pump
Switch irrigation valves
Control fertilizer injection pump
Integrate to pivot control system
Drive industrial processes

17. SmartSolution – Hybrid Power
Now anything is possible !
Support for solar and an alternative energy source
Extend the pumping day for seasonal / peak requirements
Lower operational costs from grid or generator

18. What is Smart Hybrid Pumping ?
Mixing and managing different power sources to optimize cost and performance
Plan to run solar for the majority of time and use alternative sources power for peaks, emergencies or to keep processes running
Power blending and auto switch on / switch off means that all of the solar power is used and is “topped up” by grid or generator
Operational costs of diesel and grid power are reduced
