How to Install A Solar Off Grid Well pump System

What happens here

Eric details the various components that make up the Lorentz solar water pumping system. He explains the function of each part: a Midnight Solar lightning protection device (SPD) to protect against lightning strikes; three smaller surge protection devices for individual sensors like float, level, or pressure sensors; a PV Disconnect 440-40-3 to shut down power from the solar panels; a sun sensor that tells the pump to operate only when there's sufficient sunlight, extending pump life by reducing unnecessary cycles; a PS2 controller which converts DC solar power to AC for the DC brushless motor, handles system logic, communications (including Bluetooth smartphone connectivity), and controls pressure, level, speed, and flow; grounding lugs and bare copper wire for grounding all components; a float switch for tank level control; a Liquid Pressure Sensor (LPS-1000) for pressure-based pump control; MC4 solar cable connectors for safe, plug-and-play wiring; stainless steel support cable to bear the weight of the pump and poly pipe in the well; various plumbing hardware like a well seal to prevent contamination, and U-bolts and mounting hardware for the solar panels.

Goal: Familiarize with all system components and their roles

Tools and materials

  • 1.25 inch Poly Pipe — Water delivery pipe from the submersible pump
  • Bare Copper Wire — Grounding all system components
  • Float Switch Lorentz — Controlling water level in a tank (optional accessory)
  • Grounding Lugs — Connecting grounding wire to components
  • Liquid Pressure Sensor — Controlling the pump based on pressure (optional accessory)
  • MC4 Solar Cable Connectors — Safe, plug-and-play connections for solar panel wiring
  • Mounting Hardware — Securing solar panels and other components to the support post
  • PS2 Controller Lorentz — Converting DC power to AC, managing pump functions, and providing system control/monitoring
  • PV Disconnect 440-40-3 Lorentz — Shutting down power from solar panels
  • Stainless Steel Support Cable — Supporting the weight of the submersible pump and pipe in the well
