Tip
This integration is specifically for German users under the rules of EnWG Paragraph 14a, which allows grid operators to temporarily limit power consumption of controllable loads during peak periods.
This guide will help you configure your Sofar EMS to integrate with the SmartMeterGateway (SMGW) for Paragraph 14a compliance in Germany.
What you need
- Sofar EMS with internet connectivity.
- Connection to a SmartMeterGateway (SMGW) with digital output signals.
- For standard controllers:
- Direct connection from the SMGW to the Digital Input (DI) pins on your controller.
- For lite controllers or controllers without DI pins:
- SG-ready relay module (DS1242)
- Ethernet connection from the controller to the relay module
- Connection from the SMGW to the DI pins on the relay module
How it works
The Paragraph 14a integration enables your system to respond to grid management signals from your distribution system operator (DSO). When the grid is under strain, your SmartMeterGateway will send a signal to your Sofar EMS, which will temporarily limit the power consumption of connected devices to 4.2kW by default.
