Diverting surplus PV Power, by Robin Emley

A Project to Design and Build a Controller to Route Surplus P.V. Energy into the Domestic Hot Water Supply

  1. Introduction, and “Power” v. “Energy”
  2. Detection and Measurement of surplus PV
  3. Diversion and Use of surplus PV
  4. Switching High Current Loads using a Triac
  5. Mk2 Controller Operating Modes
  6. Different ways of Measuring Voltage and Current
  7. Calibration of power and voltage, plus phase-alignment
  8. Building a Mk2 PV Router
  9. Different versions of the Arduino sketch
