LORENTZ PS2 Solar Water Pumping Systems

LORENTZ Solar pumps are a perfect match for irrigation – more sun equals more water!

The LORENTZ PS2 system has been designed and built by an engineering team who only focus on solar water pumping. This experience means they design, test and build systems where operation in the harshest, most remote environments is normal.

LORENTZ PS2 is designed to be field serviceable, the pump unit components and electronics are modular to allow for cost effective and fast replacement. Having a great feature set is only part of being a good solar water pumping system, what really matters is how efficient the system is.

Efficiency defines how much water it will pump. LORENTZ PS2 has class leading efficiency and optimized maximum power point tracking for best performance when conditions are not perfect. The system also has active power management to ensure that high ambient temperatures have minimal impact on water output.

LORENTZ PS2 makes the best use of the available power to deliver the most water possible.

Ultimate Efficiency
All LORENTZ PS2 systems use a unique DC brushless and sensorless motor named ECDRIVE. This motor is a perfect match for solar applications as it has a very high efficiency across its whole operating range. This is very different to a small AC motor where maximum efficiency is only achieved in a narrow operating band.

Solar power is always changing through the day and depending on weather conditions. The LORENTZ ECDRIVE and LORENTZ PS2 have an average daily efficiency of above 90 %, most of our competitors achieve 65 % with clear blue skies and much less when there is cloud cover.

What this high efficiency means is that you get more water from the system from less installed PV modules. Less modules means less cost, less racking, less installation time and labour. A high efficiency system means less total investment.
