Activating or Deactivating the Specifications of the Grid Operator via Local Interfaces
Qualified person
As part of grid management services, it may be necessary to implement grid operator specifications for active power limitation and for reactive power feed-in in your PV system. The Sunny Home Manager can receive these specifications via Ethernet-based communication. The grid operator can set up this link. The specifications of the grid operator must be activated via local interfaces in the Sunny Home Manager to do so.
Procedure:
- Open the menu item Grid management services under Configuration and go to Specifications of the grid operator via local interfaces.
- Configure the settings from the table based on requirements.
Requirement | Setting |
|---|---|
The Sunny Home Manager does not have to implement specifications via Modbus. | Off (default setting) |
The Sunny Home Manager has to implement specifications via Modbus. | Active (the factory-set Port 502 can normally remain set) |
If you need to change a port and there are several Modbus devices in the network, or if the grid operator specifications are to be transmitted via a certain port, manually enter the corresponding value.
If you change this port, you must also change the port in your VPN router and inform the grid operator of this change.
