LORENTZ's PS2 is the German-engineered integrated solar pumping system for small to medium applications: a matched set of controller, ECDRIVE brushless DC motor and pump end, with controllers from 150 W to 4 kW. Helical-rotor systems lift up to 450 m of head (PS2-4000 HR) while centrifugal systems deliver up to 79 m³/h (PS2-4000 C), from 4″ and 6″ wells. Average daily system efficiency of the ECDRIVE motor exceeds 90%, with controller MPPT efficiency up to 98%.

The IP68 (NEMA 6P) controller runs at full power to 50 °C ambient with active power management, offers sensor inputs for well probe, pressure, level, flow and SunSensor, and sets up in three clicks with the free PumpScanner Android app — with optional LORENTZ Global cloud monitoring. Pump ends and motor are EN 1.4301 / AISI 304 stainless steel, and AC connection options allow grid or generator operation when needed.
