This guide covers how to evaluate Lorentz systems practically, including where models like PS2-600, PS2-1800, and PS2-4000 typically fit.
The best Lorentz solar pumps are selected by duty profile, total dynamic head, and daily water volume—not by maximum nameplate alone.
Lorentz systems are widely used because they focus on integrated solar pumping architecture: pump end, motor, controller intelligence, and protections working together.
Common reasons contractors and property owners choose Lorentz:
While exact model selection depends on site data, the PS2 line is often discussed in these terms:
Typically considered for lower power demand applications and moderate water delivery targets where efficiency and simplicity are key.
Often a mid-range option for broader residential/agricultural duties with greater head or flow requirements than entry-level systems.
Used for higher-demand pumping scenarios where significant lift, volume, or both are required.
These are not one-size-fits-all labels—always confirm against pump curves for your specific well depth and target flow.
To select the right Lorentz package, collect:
Without these inputs, model selection becomes guesswork, and even premium equipment can disappoint.
A pump’s advertised capability at zero head is not meaningful for most installations.
Find your operating point based on:
Then check where that point sits on the Lorentz curve for the candidate model. A properly matched PS2 system will operate efficiently and with less stress.
For most solar pumping sites, daytime pumping to storage is the most robust approach.
Benefits:
This is true whether you deploy a Lorentz PS2-600, PS2-1800, or PS2-4000.
Lorentz controllers are not just power boxes; they are operational tools.
Useful capabilities may include:
Enable and configure protections during commissioning. Skipping this step leads to avoidable downtime.
Lorentz is commonly selected for:
In these applications, reliability and serviceability often matter more than shaving a small upfront cost.
Wattage alone does not tell you if the pump can meet head and volume at your site.
Summer demand can be significantly higher. Size for realistic peaks.
High friction losses steal performance and increase system strain.
Remote solar installations are exposed. Electrical protection is part of reliability.
When designing a Lorentz-based system, evaluate:
Where appropriate, some installers also compare Lorentz projects against other premium solar pumping packages before final selection. The best choice is the one that meets your operating target consistently.
A well-selected Lorentz system can still underperform if commissioning is rushed. During handover, make sure you receive:
This documentation reduces downtime and speeds troubleshooting if conditions change later (seasonal demand, source level shifts, or pipe modifications).
Lorentz solar pumps are a strong option when system design is done correctly. Start with accurate field data, match the curve to your real operating point, and build around storage plus controller protections.
