Adding a device

Click Add devices to open the device wizard. You will be guided through selecting the device type, manufacturer and model, and configuring the communication settings.

To add a device, you must have the Installer role on this project.

Adding a PV inverter

  1. Click Add devices and select PV Inverter as the device type.

  2. Select the manufacturer and model.

  3. Configure the communication settings (IP address, port, slave ID) according to the inverter's network configuration.

  4. Complete the wizard and save.

For Growatt inverters: if the inverter communicates via Modbus TCP, a ShineMaster data logger is present, so add the device using the ShineMaster adapter. If the inverter uses RS485, use an RS485-to-TCP converter such as the EP E300 before adding it.

Adding a battery system

Battery systems typically consist of two components:

  1. First, add the battery inverter (PCS), the power conversion system.

  2. Then add the battery management system (BMS), which monitors and protects the battery cells.

Follow the wizard for the specific brand and model. Your installer can provide the exact communication parameters.

Adding an energy meter

  1. Click Add devices and select Energy meter.

  2. Select the manufacturer and model.

  3. Configure the communication settings.

  4. If the meter is a sub-meter, link it to the appropriate parent device.

To add a virtual meter, which is a calculated meter with no physical hardware, select Virtual as the manufacturer and follow the wizard. The measurement logic is configured based on your installation.

Adding an EV charger

  1. Click Add devices and select EV charging station.

  2. Select the model and configure the communication settings.

  3. After adding, configure the connectors and energy management settings for the station as described in the charger's documentation.

Supported devices

During the Add devices wizard, you can browse all supported manufacturers and models by device type. Supported devices are listed per category (PV inverter, battery, energy meter, EV charger, etc.).

Important configuration tips

Before finalising your EMS configuration, verify the following:

  • The correct head meter is selected under project settings.

  • The grid connection type (single-phase or three-phase) matches the actual installation.

  • Import and export limits and the corresponding safety margins are set in line with your grid connection contract.

  • The strategy (cost optimisation or self-supply) matches your energy contract type.

  • All key meters and devices have the correct communication settings and are responding with live data.
