System overview
With EVLunic Pro M, several charging stations can be interconnected in the form of a master/slave
network. This makes charging with an intelligent load management possible. In addition, a connection
to a higher-level OCPP backend can take place. The charging station is equipped with different network
interfaces for these functions.
