LORENTZ has done one thing since 1993: solar water pumping. Founded in Germany and active in over 130 countries, the company builds complete pumping systems rather than bare pumps: a controller, a motor and hydraulics engineered together, wrapped in software that plans, configures and monitors the installation. This guide maps the whole ecosystem, so you can name exactly the components your project needs. SINES Export distributes the LORENTZ range wholesale.

Three platforms, one philosophy

The range is organised in three systems that cover everything from a garden well to a town water scheme:

Each platform is detailed on its own page: the PS2 system guide, the PSk2 system guide and the PSk3 hybrid systems.

The efficiency argument

PS2 pumps use the ECDRIVE brushless DC motor, designed for the one thing solar power never is: constant. Where a small AC motor only reaches its best efficiency in a narrow band, the ECDRIVE holds a very high efficiency across its whole operating range, and the PS2 system averages above 90 percent through the solar day. In practice that means the system starts earlier in the morning, keeps pumping under clouds and stops later in the evening, with fewer PV modules on the racking for the same daily volume.

CONNECTED: the software around the pumps

• PumpScanner: the Android app installers use to commission a system. Every LORENTZ pump is preconfigured; a standard setup takes three clicks, and the app reads live and historic data from the controller's built-in datalogger, which records up to ten years of operation.
• pumpMANAGER: the cloud service for fleets. Remote monitoring, remote settings and alerts for every LORENTZ system you operate, for a low monthly fee.
• COMPASS: the official planning software. It simulates the water delivery of a proposed system through the year at your exact location, before anything is ordered. Every sizing SINES Export returns on LORENTZ equipment is planned this way.
• LORENTZ Assistant and LORENTZ Global: the newer generation of the stack, used by PSk3. The Assistant app connects over Bluetooth for a two-minute commissioning and full data access, with separate rights for technicians and customers; LORENTZ Global is the cloud IoT platform behind it.

Hybrid power at every scale

Solar is the primary source; it does not have to be the only one. The range offers three levels of hybridisation. On PS2 systems, the PowerPack accessory feeds the controller from the grid or a generator when night pumping or exceptional demand requires it. On PSk2, the SmartSolution actively blends solar with grid or generator power through the SmartPSUk2, with the SmartStart starting and stopping the generator against your water targets. And the PSk3 makes hybrid native: one controller with both a DC input (400 to 850 V from the array) and an AC input (380 to 480 V from grid or generator), blending them automatically. Blending, not switching: solar is always used first, the second source only tops up what the sky did not provide, and this active mix can cut energy costs by 60 to 70 percent compared with simple source switching.

Applications across the range

The same building blocks serve four families of duties. Whatever the application, the controller optimises water delivery against the power available and the sensors connected.

Built to be serviced, not replaced

LORENTZ systems are engineered in Germany for the harshest off-grid environments: stainless steel hydraulics in AISI 304, IP68 electronics on PS2, and a deliberately modular design where pump ends, motors and electronics are field-replaceable parts rather than sealed units. Combined with the PV management accessories (DC disconnects, combiners and surge protection), the installation stays safe to work on and protected against lightning-induced surges.
