  • Page 8: Introduction

    INTRODUCTION Thank you for purchasing a LORENTZ PUMP. We set a new standard for quality and economy in solar pumping. It incorporates the best solar pump technologies that were very expensive until its introduction in 2002. Before you begin Check the model numbers of all the components of your system, and verify that they are the items that you ordered.

    PHOTO GALLERY A MODEL INSTALLATION A PS600 300Wp solar-direct system Colorado, USA This system was installed by students in a solar water pumping class. The array is set at summer tilt angle. The controller is mounted on the north side of the pole, directly under the array. This shades it from the hot mid-day sun.

    Orienting the Solar Array to Solar South For full performance, your solar array must be oriented within 10° of true (solar) south. Depending on your location, a compass reading may show an error of as much as 20°. To correct this discrepancy, apply the mag- netic declination for your region.
