Device function

You can use and configure the SMA eCharger on a stand-alone basis or in combination with Sunny Home Manager 2.0.

You carry out the device configuration via the commissioning wizard.

The SMA eCharger must always be configured in the role of System Manager in the commissioning wizard (regardless of which system configuration is selected).

Charging station in secure power supply operation

If you configure the charging station as System Manager, the charging station takes over the control at the point of interconnection and can receive control signals as a main device in conjunction with an energy meter.
Note: In secure power supply operation, the scope of functionality is limited. Charging with surplus PV energy or a specified target are not possible. If an energy meter is available and configured, then blackout protection and unbalanced load control are active.

Charging station with Sunny Home Manager 2.0

When the charging station is used in combination with Sunny Home Manager 2.0 (System Manager), the Sunny Home Manager 2.0 takes over control of the system.
Note: The SMA eCharger must be set up as System Manager because it includes a meter as a subordinate device.
