Overview of the terminal connections

This overview shows examples of system components that can be
connected for all of the terminals of the module. The components
identified with * (such as VS1 and VS3) of the system are possible
alternatives. Depending on the module's use, one of the components is
connected to the "VS1/PS2/PS3" terminal.

More complex solar systems can be created in combination with a
second solar module. Terminal assignments deviating from the terminal
overview are possible ( connection diagrams with system
schematics).
