Chapter 5: Interfacing PV Modules to Loads and Battery Modelling.

 

 

 
     
  Summary  
 
        Photovoltaic systems are designed to supply either DC or AC electricity to loads. Depending on the complexity and characteristics of the final loads connected to the photovoltaic system, different elements can be found as a part of the photovoltaic system itself. These different elements may be:
  
 
  - DC loads: lights, electric motors, etc.  
  - Batteries.  
  - AC loads: lamps, household appliances, electronic equipment, etc.  
  - Power conditioning equipment: protection and control elements, DC-DC converters, charge regulators, DC-AC converters, etc.  
 
 
        Depending on the nature of the loads their interface to the photovoltaic system implies different complexity grades. The study of the different connection options of the photovoltaic modules to the rest of the photovoltaic system components is the objective of this chapter.
