The manual describes the steps to set up ORES External Control on the Sunlight Group EMS.

When setting up this integration, permission is granted to ORES to control the necessary devices.

Supported Devices

Prerequisites

1. Add the batteries and inverters

Login to the commissioning interface and make sure the devices are added to the Sunlight Group EMS.

2. Check the grid power limits

In the settings, the grid power limits should be set correctly. Click Settings and check the highlighted setting in the image. If necessary, adjust the settings.

3. Add 'ORES' External Signal

1. Click on 'External Signals' in the top menu and click on the 'Start Wizard' button.

2. Click on the 'Distribution System Operator' button.

3. Click on the 'ORES' button.

4. Select 'ORES RTU Telecontrol' and click 'Next'.

5. Fill in the required information.

1. RS485 Interface: Select the RS485 serial port to which the ORES RTU is connected. If using a RS485-Ethernet Converter or a RS485-USB Converter, select the corresponding Ethernet or USB port.
2. Digital Input Device: Select the digital input device to which the ORES RTU is connected, this is used for the ORES RTU to detect if the connection with ORES is active.
3. Relay Device: Select the relay device to which the ORES RTU is connected, this is used for the ORES RTU to control the connection with ORES. If the relay is activated, the connection with ORES is active and ORES can control the devices. If the relay is deactivated, the connection with ORES is lost and ORES cannot control the devices.
4. Contractual permanent power: Fill in the contractual permanent power (in kW) that is agreed upon with the grid operator. This is used by our EMS to determine the maximum power that can be injected into the grid if we lose connection with ORES.

6. Select all the available devices, this is required for ORES to be able to control the devices. Then click 'Submit'.
