PS150C Submersible Pumping System

PS150 CPS150-Centric Submersible Pump For Battery Operated Or Solar Direct

  • Lift up to 22 m
  • Flow rate up to 5.0 m³/hour
  • Charger for 12/24 V batteries
  • 12V to 24V Battery Or Solar direct
  • MPPT booster for solar-direct application included
  • Cost efficiency pumping
  • Maintenance free

LORENTZ was established in Hamburg, Germany and has been a quality designer and manufacture of Solar Pumps since 1993. Through the innovative electronic controlling, outstanding manufacturing quality and a simple design, Lorentz have managed to reduce the high cost of solar water pumping. Their submersible helical rotor pumps consist of only two parts, Lorentz’s brushless motors are water filled and maintenance free, while the electronics are NOT inside the submerged motor but easily accessable on the surface.

For 12 to 24V systems (1-2 solar modules or batteries in series). Same motor and controller for solar direct or battery systems. PS-150-Centric is a submersible pump but can also be used as a floating pump.

PS150 Centric is more powerful, energy efficient, quieter and much more durable than other pumps in this range. The motor is brushless and maintenance free. No electronics in the motor

Notes on above flow chart:

  • Calculated on an average of 6 full sun hours per day
  • 65 & 150W systems= 1 x 12Vsolar panel = 17 Volt open circuit
  • 300 & 450W systems = 2 x 12V solar panels in series = 34 Volt open circuit

Note: a solar tracker will improve daily output in Summer by 40 to 50%
Note: Solar module have less output due to high temperature,dirt, manufacture tolerances etc. Choose a 20-30% larger array to compensate these effects
