SolarTrainer Profi

The teaching system is suitable for lessons in schools, vocational schools, training centres, further training institutions, technical colleges and universities. Electrical engineering knowledge on the setting-up, functioning, circuitry and installation and systems technology of photovoltaic systems can be conveyed. It is suitable for demonstrations accompanying lessons as well as for use in practice for trials.

• The conception of the system allows trials indoors and outdoors
• The individual wall-charts can be hung in the holding frames and “wired up” according to the specific test structure
• Use of module simulators for the reproducibility of measurements and in order to be independent of the time of day and the weather
• Flexible, modularly structured system
• Simple to expand, even new technologies can be integrated later
• High-quality components and materials
• Practice-oriented
• Extensive accessories available
• Well thought-out trial instructions and solutions are available

Further Measurements

• Measurement of the intensity of irradiation (ISET Sensor, handheld solar radiation measuring device)

For all tests plus 2 multimeters.
For ST 18 also ST 19 as alternative.
Due to the modular design of the SOLARTRAINER Profi, other tests are possible in addition to those which are listed. General content can also be conveyed, such as the registering of the voltage drop in the circuits, calculation of efficiency, presentation and identification of faults.
