PSk Hybrid Solar Water Pumping System

LORENTZ PSk

The Complete Hybrid Solar Water Pumping Solution

LORENTZ PSk is a family of solar water pumping systems for larger scale projects. PSk is designed to efficiently use solar power to deliver the maximum amount of water for the given conditions. When more water is needed that solar power can provide, for example 24 hour pumping, PSk becomes a true hybrid system. LORENTZ PSk hybrid is not simply switching from one power source to another but will automatically blend grid power and generator power with the core solar power supply.

PSk is an advanced solar water pumping system. The system is designed specifically to use the power of the sun to move water, so replacing the need for grid power or diesel.

Being designed as an off-grid solar water pumping system, PSk has all of the inputs, outputs and software applications built in that are needed in an integrated self-managing system.

PSk is advanced but simple to setup and operate. LORENTZ CONNECTED apps make setup and operation intuitive. Built in datalogging and Bluetooth ™ means that the real time and historic data is available wirelessly.

With PSk anything is possible

PSk systems are available from 7kW to 100kW with a wide range of submersible and surface pumps and motors.

With PSk you will benefit from:

No infrastructure to install

Using solar power means that you can install a pumping system almost anywhere, irrespective of power infrastructure availability and the associated costs. PSk2 is designed for the harshest off-grid environments.

Low operational costs

Operational cost savings are achieved as the system requires no fossil fuels, can be fully remotely managed and is designed to have a long working life. The result is very low, or no operating costs.

Right sizing

With infinite smart motor control PSk2 is very gentle on pump motors, this both extends the system life and allows for any generators that are integrated into the system to be much smaller than for conventional pump systems.

Lowest project risk

As PSk2 is designed to be a complete system, it has all of the needed software and hardware for your water project. The result is that your projects are delivered on time, on budget and without technical risk.

Designed for Solar Water Pumping

PSk has been designed from the first white board sketches to be a solar pumping system. The 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.

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. PSk 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.

Hybrid Power

All LORENTZ PSk systems can operate on solar, from generator / grid power or in hybrid configuration. PSk3-7 and PSk3-15 have integrated hybrid, larger power class systems are modular to allow customers the choice for hybrid. Hybrid means seamlessly blending solar power with grid or generator power sources.

The PSk becomes the brain of your water system, looking at what power is available, using solar power wherever possible and only starting a generator or putting a load on the power grid when there is not enough sun to meet your water needs. This function is not a simple switching system, there is active blending of power sources meaning that your solar investment is fully utilized and that the use of expensive, non-renewable power is minimized.

LORENTZ PSk hybrid manages all of this for you, including generator auto start and stop, timed starts and also volume based, level based or pressure based decision making. This flexibility means that the most efficient and effective solutions can be built to meet any water need.

The Complete Solution

PSk is designed to be a complete solar water pumping system comprising of a specialized pump controller and carefully matched pumps. PSk has multiple 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 included SunSensor which measures the available irradiation and then makes decisions of what to do based on the available power. The Sun Sensor also avoids unnecessary stop start cycles, extending the life of the pump and motor.

PSk2 is a complete solution “out of the box” without the need for building additional switching cabinets or PLC units.

CONNECTED

LORENTZ PSk is configured on site using LORENTZ CONNECTED smartphone apps, PumpScanner and Assistant. Configuration, operations and viewing data is intuitive. Common configuration is done with three clicks and there is full access to configure system behavior based on the additional sensor inputs.

The PSk constantly records operational data and provides access to rich information for both customers and technicians.

The PSk can also be connected to the LORENTZ Global managed service. LORENTZ Global is a cloud delivered, pay monthly service that takes away the complexity of remote monitoring and management. One low fee means that you can see exactly what the system is doing, make changes to settings and receive alerts on all of your systems irrespective of location.
