Description
Stand alone operation of photovoltaic modules excludes any access to a public mains grid. This kind of photovoltaic usage is chosen typically for applications in remote locations.
It is conceptualized as an extension for it and provides typical components for stand alone photovoltaic systems. This includes a charge controller, an inverter and an accumulator. These components enable conversion of the solar electricity, provide supply on demand and ensure system safety.
A connection cable feeds the photovoltaic DC current from it to the input of it. Inside it the DC current passes safety devices and enters the charge controller. The charge controller adapts the voltage level for accumulator charging or for direct consumption. An inverter enables usage of typical AC consumers.
Learning Objectives/Experiments
Familiarisation with practical components for stand alone use of photovoltaic electricity
Functioning of a DC switch-disconnector and over voltage protection
Functioning of a charge regulator with integrated maximum power point tracking
Influence of the workload on the efficiency of components
Influence of fluctuations in solar energy and/or electricity usage on the overall system efficiency
