LORENTZ PS2 Solar Pool Pumps are high quality products designed for use in residential and commercial swimming pools and spas. In most pool applications all of the filtration needs can be met directly from solar panels meaning no electricity costs and significant benefits to the environment. The Lorentz PS2-600-CS-17-1 and PS2-1800-CS-37-1 are both solar-powered swimming pool pumps, but they differ significantly in capacity, target pool size, and solar power requirements.
Key Differences at a Glance

- Target Pool Size: The PS2-600 is designed for residential pools (up to 55,000 litres.) The PS2-1800 is built for larger residential or commercial pools (50,000 to 100,000 litres)
- Max Flow Rate: The PS2-600 pushes a max of 18,000 litres per hour, while the PS2-1800 handles up to 36,000 litres per hour.
- Max Total Dynamic Head (TDH): The PS2-600 reaches a max head of 12m compared to 14 m for the PS2-1800.
- System Power & Solar Panels: The PS2-600 has a maximum power limit of 0.70kW (requiring around 990 Wp of solar panels. The larger PS2-1800 system operates at a maximum of 1.8kW
- Input Voltage: The PS2-600 controller accepts a max PV voltage of 150V, whereas the PS2-1800 handles up to 200V Shared Features Both systems are highly efficient, engineered in Germany a nd share the following traits:

- Direct Solar Connection: They run directly from PV modules without needing batteries or grid power, though they do support optional battery integration.
- Motor & Tech: They use maintenance-free, brushless DC ECDRIVE motors with advanced MPPT (Maximum Power Point Tracking) technology to optimize pumping in varying sunlight conditions.
- Control Features: Both feature inbuilt pumpManager connectivity, dry-run protection, and smartphone management. Expert Perspectives Looking at real-world usage and professional commentary, here is what installers and users have to say:
Lorentz Case Studies on Commercial Swimming Pools Lorentz’s own reports on large-scale aquatic installations highlight the sheer capability of the 1800-watt models for maintaining vast water volumes, relying on high-efficiency DC drives and massive solar arrays.

“ Using a computer model eight PS1800 CS-37-1 pumps were specified to meet the pumping need. To power the system across the holiday season (May to September) a solar generator of 22 kWp was specified and installed."

“ The LORENTZ pumps use DC brushless motors which are very reliable and provide efficiencies of over 90 %. The high efficiency means less solar modules are required"
