Description
Feeding electricity from photovoltaic solar modules into the mains grid requires several special system components. These components enable conversion and capture of the solar electricity and ensure system safety.
The unit contains these components and is conceptualized as an extension for the trainer.
The photovoltaic DC current from it is fed to the input of it via a connection cable. Inside the DC current passes safety devices and enters the inverter. The inverter transforms the DC into AC current. The inverter also optimizes voltage and current to ensure that the photovoltaivc modules produce maximum possible power.
Learning Objectives/Experiments
Familiarisation with components from grid connected use of photovoltaic power
Functioning of a DC switch-disconnector and over voltage protection
Functioning of a grid connected inverter with maximum power point tracking
