4 Configuration

In order to be able to use Modbus registers for grid management services, the grid management service must be
configured on the SMA System Manager. In connection with an energy meter, an SMA System Manager takes over
closed-loop control at the point of interconnection and can control or regulate subordinate inverters. The System
Manager also takes over system monitoring and communication to the Sunny Portal powered by ennexOS.
Requirement:
☐ The correct country standard must be selected during commissioning.
☐ You must be logged in on the user interface of the device that has been configured as System Manager.
☐ The Modbus server must be activated in the device that has been configured as the System Manager (the
Modbus server is only available via Modbus TCP (not UDP)).
Procedure:
1. Select the menu item Grid management services in the menu Configuration.
2. Select the button Configuration and activation in the Active power method and Reactive power method
row.
3. Select the operating mode Closed loop or Open loop.
4. Select the signal source Modbus.
5. Make settings in accordance with the grid operator's specifications and confirm each step by clicking on
