Solar pumping systems for reliable Water Supply in Africa

All 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 PS2 have an average daily efficiency of above 90 %.

PS2 controllers are available from 150 W to 4 kW. The controller includes the electronic to drive the ECDRIVE brushless DC motor, software for our water applications, all the inputs you will ever need, data logging, plus intelligent control over the whole system to give you the most water possible.

The 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. 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. 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.

PS2 is designed to be a complete solar water pumping system comprising of a specialized pump controller and carefully matched pumps. PS2 has eight sensor inputs that allow analogue and digital sensors to be connected. This combination of sensors with the powerful inbuilt software applications allows for full pump control and water specific applications. The system also has an inbuilt Sun Sensor which measures the available irradiation and then makes decisions of what to do based on the available power. The SunSensor also avoids unnecessary stop start cycles which increase pump wear.
