For load management with the cFos Charging Manager (*) you need a license for each charging point. cFos EVSEs are not counted here.
If you use a cFos EVSE as a master for your load management, three charging points are already included. All other charging points each require an additional license. Here again, cFos EVSEs are not counted.
So if you set up load management only with cFos EVSEs, there are no additional costs for load management!
With the OCPP gateway you can connect external EVSEs to an OCPP backend if these EVSEs do not support OCPP or are incompatible with an existing OCPP backend. If you are planning to use such EVSEs in a system with the cFos Charging Manager and would like to connect them to an OCPP backend, you need a license for each external EVSE. You do not need an OCPP gateway license for the cFos EVSEs. (**)
(*) Windows or Raspberry Pi version, as well as the charging manager integrated in the cFos EVSE.
(**) The cFos EVSEs even allow parallel operation with OCPP on a billing backend and at the same time via Modbus in a load management.
