Energy management systems (EMS)

The Spelsberg Wallbox can be incorporated as part of an energy management system (EMS). The EMS controls all energy flows in the system, including PV systems, energy storage and loads. Thanks to intelligent control of the energy flows, in the ideal situation only self-generated energy is used as a supply. This significantly increases consumption from own sources and independence from mains power. Please refer to our compatibility list to find out which energy management systems the Spelsberg Wallbox is compatible with. List of compatible EMS.

 

The Spelsberg Wallbox Smart Pro offers the following options for connection to an EMS:

There are three ways to connect the Spelsberg Wallbox to an energy management system. To do this, open the app and go to System and then to Settings. Next click System integration and then External control. At this point, you can choose between integration via SMA SEMP, EEBus or Modbus TCP and continue with the configuration as described below. In principle, all devices must be in the same network for integration. Information on network integration can be found here Network integration.
