electronic circuitry for a solar power system falls into a number of
- 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).
- Monitoring and control of battery charge, to prevent
overcharging and excessive drain from the batteries.
- Efficient conversion of battery voltage to match the need
of loads, such as dc-dc conversion and dc-ac inversion.
- EMI reduction.
