Solar Electrics


The electronic circuitry for a solar power system falls into a number of categories:
  1. Regulation of current flow from the solar modules to the batteries. For best efficiency this must extract the maximum power from the solar module, by maximizing the current flow to the battery using switch mode techniques (a low power example is discussed in http://www.otherpower.com/images/scimages/638/2IFD_MPPT_.pdf).
  2. Monitoring and control of battery charge, to prevent overcharging and excessive drain from the batteries.
  3. Efficient conversion of battery voltage to match the need of loads, such as dc-dc conversion and dc-ac inversion.
  4. EMI reduction.
