"Charging with control by an external energy manager" involves the use of an external 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.
All parameters are configured via a web-based platform of the EMS. All energy flows are centrally displayed via the energy manager. This allows precise operating times according to the availability of the PV current.
The configuration in the wall box is restricted to the connection with the respective EMS and the associated communication interface. To do this, open the Spelsberg Wallbox 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.
To configure the Spelsberg Wallbox Smart Pro with the Sunny Home Manager 2.0 via SMA SEMP, follow the settings in the Spelsberg Wallbox app. Detailed information on the various charging modes and the functions of the Spelsberg Wallbox Smart Pro in conjunction with the Sunny Home Manager 2.0 can be found here. The following parameters must be set:
Parameter overview | |
App Parameter | Settings |
SMA SEMP interface | Activate |
Automatic phase disconnection | Activate Dead time: Time taken for pausing the charging process, which should be taken into account when switching between 1-phase and 3-phase charging. A minimum of 60 seconds should be set. |
SMA charging mode | Selection:
|
SMA minimum energy demand [kWh] | Input [0-1,000 kWh] _ _ _ _ _ |
SMA maximum energy demand [kWh] | Input [0-1,000 kWh] _ _ _ _ _ |
SMA planned departure time | Enter the desired time in the format HH:MM, by when the configured minimum energy demand is to be charged. |
Current limitation in the event of failure of the SEMP gateway [A] | Set the maximum charging current (6 - 16 A), in 1 A steps in the event of loss of connection to the Sunny Home Manager 2.0 |
Once parametrisation is complete, click Apply and transfer the settings to the Spelsberg Wallbox via NFC or network communication.
To configure the Spelsberg Wallbox Smart Pro via EEBus, follow the settings in the Spelsberg Wallbox app. The following parameters must be set.
